A BIG Day

We are potters again!

We have our hands in clay again – finally. It’s been 19 months and 3 days since the fire.
Today we made our first batch of clay in the new pottery clay making room in the new shed.
I spent part of Friday fabricating a wedging bench, because there would be nowhere to work the new batch of clay coming out of the dough mixer into balls and then blocks, before bagging them up, and moving them to the new clay boxes. So I needed a strong bench.
Every step has been considered and planned, so I have already built the plastic lined clay boxes. Installed the dust extractor. Rebuilt the dough mixer – for the 2nd time after it was burnt in the pottery fire in 1983 and then again in 2019. Making the wedging/clay prep bench was the last step.


I incorporated a marine ply splash back on my bench, so that in the future, I can stack clay on to the bench quite high prior to pugging, without it falling – that is, once we manage to get a pug mill. We have had one gifted to us, but as we are all in lock down. I can’t get it.We are making clay anyway and bagging it up to age in the new clay box, so that when we get a pug mill, we will vacuum pug it and can use it straight away.



All the dry powdered ingredients are accurately weighed out on the scales and placed slowly and carefully into the dough mixer bowl to minimise any flurry of dust rising up out of the bowl. Any dust that does rise disappears up into the bright orange tube of the exhaust fan mechanism and is issued outside.We mixed the powders dry for a few minutes, until all the ingredients were the same colour and all sense of difference was mixed and mingled in together. Then I added the exact, measured amount of water and let it continue to mix for several more minutes, until the batch becomes stiff and starts to ‘ball-up’. 
I’ve learnt that this is the time to add the remaining small amount of water that was withheld from the first pour. This last issue of extra water wets the stiffer ‘balled-up’ ingredients and softens them, I then Iet the mixer run for several more minutes until everything is smooth and plastic.
Amazingly, when I rebuilt the mixer this time around I had to reshape the mixing bowl that had gone out of shape during the fire and had 4 large splits in the metal rim.The bowl had been a little bit pear shaped since the first fire in ’83. So much so that the mixing arm used to bang into the side of the mis-shapen bowl and had scraped all the paint off in one place. Now after this last fire and re-working, I had to clamp it into some sort of semblance of a round shape as I panel beat it back into a useful shape. I had no real idea of how to approach a job like this. I’m not trained in metal work, just entirely self taught. I muddle through most difficult jobs, lurching from crisis to crisis. I manage to succeed by shear graft and persistence, rather than knowledge and skill. So, I was totally amazed that when I came to use the dough mixer this time round,  I discovered that I had indeed managed to make it almost perfectly round again. Well, not perfectly round, it still has a distinct wobble in it, but there is no impact on the wobbly side anymore. There is no wobbly side! Just a general overall wobble. Sort of evenly wobbly! I managed against all the odds to repair it really well. I fully expected it to be worse, not better. I’m no panel beater. So I am really amazed! it’s such a fluke! I am very pleased.



As the clay absorbs the water, it stiffens and balls up.



The hardest part of this ‘dry-mix’ clay making, is having to dig the stiff and sticky plastic clay out of the mixer bowl by hand. In the past, I would unload the clay from each batch into a bathtub next to the mixer. I used to make 8 batches in a row, one after the other, and that would make up a tonne of clay. Enough to fill one clay box. Then I would pug it all through the pug mill with no vacuum to speed up the process (the vacuum process slows down the speed of through put). I stacked all the first pugs of clay in a large pyramid stack and then re-pugged it all again with the vacuum on. This time slicing off all the ends of the previous pug sausages and mixing them all together in one handful into the pug mill hopper. This ensured that any mistakes or slight variations in the 8 different mixes were all averaged out in the final pug sausages.
It used to take me all day to make up, twice pug, then bag and box a tonne of clay. It was a long day and quite hard work overall. I stopped making dry mix clay over a decade ago. For the past ten years or so, I was crushing, grinding, and ball milling all my porcelain stones, to make my porcelain stone ‘clay’. The only time that I used the dough mixer in the past few years, was to make a big batch of wadding for the wood fired kiln.
However, now, on this occasion, we have no pug mill, so it’s all to be done by hand, we work it up by hand into round balls of a couple of kilos, pounding 3 of these together into a block and stacking 3 blocks one on top of the other, before bagging the lot.Each batch we make is 130 kilos and we make 2 batches. It has taken us about an hour and a half for the first batch, but we get better at it, and the second batch only takes one hour to weight out all the ingredients, mix them and unload the batch and bag it all up and place it into the clay box.
I scrape down the mixing bowl between each batch, because I don’t want the thin remnants of clay drying out and going hard between batches and causing lumps later, that will need to be hand wedged to be sorted out.



After we have finished the 2nd batch, I sponge down the mixer and clean the bowl, ready for the next use.



As I made the mix a little wet, to allow the water to fully integrate into the clay as it ages. We left the last 25 kgs out over night to stiffen up a little, so that we can wedge it up tomorrow, wire cutting it and kneading it to remove the air bubbles and get this small amount ready for the wheel. I will need to make a series of clay test to get to know this clay, but also to provide tiles for glaze testing. We aren’t ready for any throwing yet.



We haven’t moved the potters wheels that we have been given and loaned by our friends out of the storage barn yet. There is no room to install them in the studio just now, as it is full of stuff that I am still working on, but the time is getting closer. I still need to finish welding up the benches and table for the centre work station of the studio and a table for the gallery. That will be my next job. Meanwhile, the clay is resting in the clay box and hopefully ageing and improving a little

Ventilation

There are now lots of small jobs to convert our cheap and nasty metal framed farm shed into a functional pottery studio. I had to fill the little gap above the wooden windows, between the metal lintel bar that supports the arch brickwork. This is to stop sparks and vermin getting into the cavity. It also looks better and more ‘finished’, but really, I just had to get it done to complete the building so as to get our final approval and occupancy certificate. 

The next most pressing job was to install OH&S ventilation. A fan in the materials processing rooms to take the dust away from the rock crushers and clay mixers. I never had to worry about forced air ventilation in the past, as the machines were more or less outside in the breezeway between the two pottery buildings. Now that I have them all in the one sealed room. It is essential that I fabricate and install good ventilation.


This metal tube has some 2nd hand/re-cycled 1.5mm stainless steel mesh inserted to stop sparks and insects getting into the building.


And a cheap batroom fan in the other end that will be inside the room.

Connected to a long flexible air hose.


With the exhaust fan embedded in the wall, I can direct the cheap flexible suction vent hose to any machine in the room.

I have no idea how other people might achieve this sort of dust extraction, but this is one cheap alternative solution, and mostly home made.

Clay? What OH&S risk?

Final Inspection and Prepping for Clay Making

We have been working a bit frantically to get all the things on the list completed so that we can get our final inspection, which, if our building passes, will entitle us to get our occupancy certificate. Once we have this, we can legally move in and fill the place up with pottery equipment and start to use the space as it was intended.
The Council Building Inspector called in today in the late afternoon. He gave our work a good scrute and declared that we had completed everything on the list to his satisfaction. He issued us with a carbon copy of his Final Inspection Report and was very complementary about the way that we had transformed a cheap, kit form, tin shed(s) into an interesting building. He commented on our sandstock brickwork and the arch window that visually links the new pottery shed to the Old School building and our use of recycled, old gal iron to enhance the visual amenity of this historic site. I was chuffed.
We celebrate with a dozen oysters off the fresh fish truck that come up from the coast on Wednesday, Thursday and Friday, paired with a couple of cheap sushi trays.


Now we can legally move in. Actually, he didn’t comment on the fact that we already had moved in our kilns, clay mixers, rock crushers and ball mills, the benches, pan break and guillotine, they are all in there and ready for work. I have been using the maintenance shed for a couple of months now to restore my machines and actually make the components to fit out the rest of the building.

One of the first things on my list now, is to make some clay, so that it can ‘age’ for a while, to improve its plasticity, so that when we start to make pots again, the clay will be more workable and respond better on the potters wheel. Having a bit of time to age is very important for freshly made clay, when it is made from powdered materials.

Ageing isn’t so important when clay is made by the wet method involving a slow stiffening back from a liquid mix where the raw material is in the crude natural form straight from the ground.


It might be worth explaining here a little bit about clay. When clay is in its natural crude form, it has a multitude of fine, flat, hexagonal particles, sort of laminated like pages of a book. When the clay is soaked in water and stirred into a watery ‘slip’ or slurry, these flat sheet like crystals are slowly liberated one by one and flake off from the ‘book’. This process takes time. The finer the particles, the more ‘plastic’ and workable the clay can be, realising the best of its potential, but it also takes a long time to get the water in between the various surfaces. 


Stirring the clay and water mix or ’slip’ up into a fine slurry, sieving it to remove any unwanted particles and then letting the slip sit and settle takes time. Sometimes, the clay particles in the slip don’t settle out due to gravity allowing the water to come to the top where it can be decanted off. If the slip doesn’t settle out, then the mixture has to be tested, measured and treated. This involves measuring the pH of the slip. Usually, the clay will need a small addition of an acid to change the pH to very slightly acid.

 
Clay particles have an electrostatic charge on their surface. Clay chemistry is very complex, but suffice to say briefly here that clay particles are a little bit like small magnets. What is needed is to get the positive and negative charges to balance so that they attract each other and not to repel. If they are repelling each other the clay will never settle, but stay suspended and cloudy forever. Once acid treated they can be made to become attractive and will form larger clumps that are affected by gravity, and so settle to the bottom, allowing the water to be forced up where it can be decanted off. This process is called ‘flocculating’ . Think of a mob of sheep forming a flock.


I’ve tried many different ways of flocculating my clay particles. Old red wine that was undrinkable due to cork taint, there isn’t much red wine that I wont drink, but cork taint is one that isn’t drinkable, then I’ve tried cheap commercial vinegar, even cheaper imitation vinegar, dilute brick cleaning acid from the hardware, or epsom salts, but my ‘go-to’ dilute acid is the water in our old pottery water tank full of rain water ( carbonic acid) that has been affected by the constant fall of gum tree leaves onto the old pottery iron roof. This caused the roof to rust and created a moderately acidic solution of carbonic and tannic acid. It came out of the tank pale brown, like cold black tea. When I used this water to make slip I didn’t need to add extra acid. I much prefer this natural method of flocculation. It suits my life philosophy of living naturally as possible and treading gently combined with minimal consumption. Once the clay has settled to the bottom and the excess water removed, the thick slurry can be placed out side in the sun and wind to stiffen. 


This wet method using crude clay is a very slow process. So to speed thing up potters use can use dried powdered kaolin and powdered non-plastics like felspar and silica blended together in a set recipe in the dry state and then just enough water is added to bring the mix to the required plastic consistency. This is akin to making a cake. Although fast, this method doesn’t wet all the available fine particles and the clay doesn’t develop its full potential plasticity. Its a compromise like everything else in life. This dry mix method is fast and efficient and with a tiny addition of some extra plasticiser like bentonite, the preemptive addition of some acid to the water and a period of ageing, then a reasonable result can be obtained. That is what I intend to attempt this coming week. 


When life settles down a little and we have more time, I will make the next batch of clay body by the wet method, using my larger ball mill to mix the liquid slip and allow the slip to sit as a liquid in a large plastic drum for some time and then slowly dry the slip out. This is designed to realise the maximum potential plasticity of the clay body, and is what I have been doing for the past decade to get the most out of my porcelain stones. As they are not inherently plastic, they need all the help that they can get. Tragically, In the fire I lost several tonnes of milled porcelain stone body that I had been ageing for up to 10 years for use in my dotage. 


Before I can make this first batch of quick and dirty clay, I want to make a clay storage box to keep it in. Clay ages best somewhere cool, dark and where it will keep damp with a minimal amount of condensation, that means no direct sunlight, so a plastic lined, heavy duty wooden box has worked well for us for the past 35 years. 


Luckily, back in 1983 when we were building our last pottery shed, after our 2nd fire, I saw two packing cases on the side of the road placed there outside a factory for the taking. 1200mm x 1200mm x 900mm. Big enough to hold a tonne each. We would fill them and when we had used up the first tonne of clay, we would make another tonne to replace it, and then use the other box full while the freshly made tonne was left to age and improve. We kept up this swap and go method of ageing our clays for many years.
Unless I can find two more suitably sized packing cases on my way to the timber-yard today, I’ll be buying a couple of sheets of ply wood and a big sheet of heavy duty plastic, to make some new clay storage boxes.


I still need to line them with plastic – maybe tomorrow?

Our Old Twice Burnt Dough Mixer Proves to be a ‘Pheonix’ mixer

Janine and I bought a very old and well used bakery dough mixer back in 1978. This was a time when a lot of old, small, family run bakeries were being forced out of business by the big multinational food corporations, and a trend towards people buying mass produced bread in super markets, rather than going to the small family bakery.We didn’t have 3 phase power back in those days, so I adapted the dough mixer to run on the power from a 5HP petrol engine interfaced through a rather snazzy torque converter. The sort of thing that adapts automatic gear boxes to engines in cars. I was given it, so didn’t realise how expensive they were.
We used that dough mixer in conjunction with a 200 mm. Venco de-airing pug mill for 5 years to mix all our clay bodies. Tragically, That pottery burnt down in 1983. That was a timber building and was totally destroyed by the fire. What was really amazing, was that I was able to rebuild both the pug mill and the dough mixer from the melted and charred remains. I spent a lot of time working on that equipment to get it going again. Luckily this machine was housed in a corner of the building with 2 sets of glass double doors on the corner, so as to allow for good ventilation. As this part of the building had very little wood in it,  the machine didn’t get too hot during the fire and none of the cast iron parts cracked.
The shaft of the dough mixer got rather bent during the fire, so had a very noticeable wobble in it when I got it going again, but at least I got it going. It was a bit of a mess, but I managed to keep it going for the next 36 years. After that fire, I converted it to a 3 hp single phase electric motor. The biggest motor that you can plug into a 15 amp power point, as that was all the power that we had at the time. It only just managed to do the job, as it wasn’t really powerfull enough, but I was carefull with it and nursed it along. I set it up with a home made, somewhat loose, slip-belt clutch as torque converters are so expensive.

After this last fire in 2019, The machine really got cooked, That’s it in the centre of the picture above, in the burnt out shed. Fortunately, the fire didn’t crack the castings. However, this time the main shaft was so badly bent, that it wouldn’t even rotate. I gave up on it, as I had so much to do to rebuild the new pottery shed that I couldn’t see myself ever really finding the time to fix it. Then, when my friend John Edye retired. I was able to buy his dough mixer. Very lucky timing. I didn’t have a pottery to put it in at the time, but bought it anyway, to make sure that I had it ready for when I could install it. As it happened, John also had loads of other jobs to do, so it sat there for several months, before we could find a mutual time that suited us both, for me to go and collect it.
In the interval, my friend Ross turned up one day, He is a really amazing person, who has so much knowledge and life experience with machinery. He saw me working on some of my ruined gear and asked what I planned for the dough mixer. I told him that I had given up on it for the time being, but couldn’t bring myself to abandon it. Ross had a good look at it and said that he thought that he could extract the main shaft from the gearbox and straighten it in his hydraulic press. He had done other jobs like that in the past. So I said “yes please, have a go at it”. I know that I won’t get around to it for a long time – if ever.
Luckily, I had poured spent engine oil all over most of the machines to stop them from rusting too much and greased all the bearings to prevent them from siezing up, so as to preserve them until I could find the time to get to them and try to fix them. I also bought a massive tarpolin to cover them. This turned out to be a smart move, as they remained there, under cover, for over a year. I found out through this experience that there is a massive amount of condensation under a plastic tarp, so all the machines that wern’t oiled were very badly rusted.
We worked on the dough mixer. Ross and I were able to dismantle all of the moving parts that still moved, and Ross took the main shaft home with him. He called a few weeks ago to say that it was now back in a good shape. Not perfect, but very good. We water-blasted the carcas to remove all the old oil, carbon, ash and burnt paint from it and I moved all the other bits inside, to keep them dry while I set about re-assembling the gearbox and all other moving parts. Ross organised a new oil seal and I had removed the main bearings and soaked it in oil to rinse clean and preserve them.

At this point, it’s looking a bit like a burnt out darlek!

A new 3 phase electric motor, a good clean, some rust converter and a coat of zinc primer and it starts to look as though it will go again.
The mixing bowl on the other hand had copped a bit of a hiding. It was split in 4 places around the rim and was no longer completely round, in fact it was a little bit heart shaped. I spent some time on it, a bit at a time, clamping it back in shape and tack welding it together,  getting it as round as possible, then welding all the splits back solid again.

After a week of nights, doing all the usual things, rust converter, penetrol sealer, zinc primer, several top coats of hard gloss oil paint and its looking great.

Everything is coming together now. The housing, gearbox and mixing arm have been given their severel top coats and are looking good. I bought a new 3 phase motor, new drive belts and electricals, so when I plugged it in the first time, and it actually went – I was really moved that it was back from the dead. Again! Thanks to Ross! 

Now I need a pug mill and we are back in business, ready to make clay again. This restored ‘phoenix like’ twice burnt, and twice restored dough mixer sits in the same room as John Edye’s mixer that I bought when I had absolutely no idea that mine might be recoverable. Hints of ‘two-sheds Jackson’ here. Steve ‘two-mixers’ Harrison.
Weirdly, my old ruined one is now ready to work before I have finally gotten around to finishing cleaning out and painting the bowl of John’s machine.

Rust converter being applied inside the bowl and the mixing arm to neutralise the rust, by converting the iron oxide that is very susceptible to oxidation with air when it gets wet, and converting the iron oxide to iron phosphate, which is quite stable and inhibits further rusting. However. The iron phosphate really needs to be sealed with a water impermeable membrane. In this case it also needs to be fairly impact and wear resistant. I have found that an oil based, high zinc, machinery paint works quite well. Well, similar stuff that I used in 1983, the first time that I restored this mixing bowl worked really well and lasted for 36 years! Of course, there is no guarantee that anything on sale today will last as long.

The bowl after rust conversion. I sent this image to John and we both agreed that the inside looked al to like an ancient ‘hare’s fur’ tenmoku glazed tea bowl.

Ready for the primer and top coat.

The first coat going on.

ready for work.

High hopes are not enough

After I had such a terrible firing a couple of weeks ago. I got stuck in and remade all the work. I’ve filled the shelves and had 2 solar fired biscuit firings and I am almost ready for the third. Then I can pack the wood fired kiln again. Hopefully this time with more success.

I had slaked down all the turnings from the last work session and made half of this work from the recycled sericite bodies. I have made test batches of 5 different sericite this time round. I have 2 Chinese minerals, 1 Korean, one English and one Australian in this batch. Although strictly speaking, the local one is a complex mixture of Illite, kaolinite, quartz and felspar.

I’m always looking for something that I don’t know, so the search is a bit difficult as I’m working semi-blind. I know more or less what I want and how to achieve it. After all, I have been doing this research for the past 40 years and more. But getting what I consider excellent results is always elusive and difficult. It doesn’t help when the kiln shelves break and collapse… Still, I’m over that and all the new work is made and drying. I’m just turning the last of the throwing today.

Sericite is funny stuff. It isn’t plastic like other clays, it’s quite short in most cases and has to be coaxed along to get any height in the form. I learnt to throw the inside of the form as I want it, leaving a thick wall to retain the form without it squatting. I then have to turn quite a bit of material off the outside to realise the finished form from the thick lump at the base.

Although sericite isn’t plastic, it still shrinks quite a lot and has a terrible tendency to crack in drying where it is thick. I have developed a few techniques to cope with theses peculiarities. I’ve learn’t to throw everything on batts, as lifting the pot with my fingers causes a memory distortion in the body that shows up later in drying. I’ve learn to ‘polish’ the out side of the clay after I have finished throwing, to seal any possible defects or weak spots that might start a crack during the early stages of drying and stiffening. I have also learnt to turn the bases in stages. Thinning out the clay as soon as it is stiff enough. This stuff can’t be turned like ‘normal’ clay based bodies. It has to be very firm, almost dry to get a smooth finish. If turned too early, it chips and tears, making an awful mess of the fine surface. It’s a bit like cutting soft goats cheese, it just tears.

Trimming the base of this pot almost bone dry

I’m getting better success rate these days with each variation and improvement of these techniques. It’s a little frustrating to loose so many pots, but they slake down quickly and can be stiffened in plaster tubs out side, then re-thrown within a week.

It would be better to leave the body to ‘age’ in a cool dark place for a month or two, but with so many variations of sericite porcelain bodies in constant testing and development. I’d loose track. As it is I really have to concentrate and keep very good records, marking every bag with a permanent marker, identifying every bucket of turnings in the same way and carrying this over to the slaked recycled material in the buckets and in the plaster tubs. It’s quite a paper trail of provenance, keeping track of it all. I also keep a daily diary in the workshop of what I’m throwing and what I’m throwing it out of. Every pot gets inscribed with the batch of body and later identified with oxide as to which glaze I used. I also keep log books for the glaze and the body ball mills, so that I know what I made, the date it was done, and what it was made from. I always seem to have a dozen different batches on the go at any one time and they all need their own bucket and bag storage space. It’s organised chaos.

I’m nothing if not thorough. I have to be. With over 3,000 glaze tests and hundreds of clay body tests. I need to keep track. I really want to make simple, elegant, beautiful things. But things with a particular character that I admire. Just a little bit ‘damaged’ or altered by the process of their making. Perhaps I should say ‘enhanced’ by its process and journey, plus the unique quality of its material. I like my pots to have a story embedded in their form and surface. I can pick them up years later and ‘read’ that story. I like that.

I’ve just made a few more white tenmoku bowls. They are slightly bigger, fuller and rounder, more generous in feeling, less austere. I haven’t finished turning them yet. They still need more work over the next few days, but I have high hopes for them.

Unfortunately high hopes are not enough. It’s long term, steady, pains taking, thorough and often boring, consistent research that makes progress for me.

That’s really rewarding!

27 Kilns in 27 days – vol 3

Vol. 3. Recent industrial wood fired celadon tunnel kiln.

While in the Longquan traditional celadon region researching celadon, we took some time out to visit a former celadon factory, that was forced to close when the economy was modernised. It has now re-opened as a celadon museum/cultural park.

I found it a bit shallow and lacking in depth. That is to say what was there didn’t grab me. It may be of interest to the more general tourist, but there wasn’t enough there to speak to me, as I’m interested in the more intricate details and technical information/insights that could be included, but weren’t.

However, there was an old wood fired tunnel kiln that had been restored. This kiln was the main means of firing the celadons here right up until 1998. One can understand why it went broke and couldn’t compete with more modern factories with up to date facilities and equipment.

There was also an clay processing section that used the old fashioned water-driven, wooden clay hammers, that is a technology that dates back 1000 years. It was exactly fitted with the age of the kiln technology, So out of date for a factory setting, it is hard to believe that it managed to last right up until the 1990’s.

Clearly, this equipment hasn’t been used for many years, possibly since 1998? Just like the kiln.

All the pots produced in the wood fired tunnel kiln, were packed in saggers to protect the ware from the fly ash from the wood fuel, which is so important when making a subtle glaze like celadon.

It is interesting to see that sometime between 60 and 20 or so years ago, they wrapped some parts of the wooden roof frame with ceramic fibre to stop it singeing or charring during firing.

The saggers that were used in the kiln firings are these days used as retaining walls and breeze way walls.

Back Home and Busy

I’m back home again from my month of researching in Korea now and I’m suddenly very busy.

Not just catching up on the past emails and book orders, but immediate things like the fact that the big gum tree on the corner of our street that was hit by lighting just before I went away, has needed to be lopped and made safe. The fire brigade came and put out the fire, but didn’t fix the mess, as it’s not their job. The tree was badly damaged, burnt, split and shattered. It’s not our tree either.

While I was away, Janine had been ‘at’ the council to make the tree safe, as it is out on the foot path and is not on our property. We can’t legally touch their trees. There are rules! We could get fined.
So now the tree loppers are here and have pruned the tree back to a stubby trunk. They leave all the loppings at the base of the tree, so that we can collect it for fire wood. If we hadn’t asked, they would have shredded it all down to wood chips in their huge shredder. So the current, pressing job, is to collect the wood. I have a load of other things on my list, but priorities change day to day as we respond to each situation.
As soon as the tree loppers go we are out there. I know from bitter experience that some particular neighbours will take it from under our noises if we don’t act quickly.
A few years ago,property I helped our direct next-door neighbour to chop up a tree that had fallen on his property down by the back lane. I couldn’t take it all away at the time, but cut it all up into small slabs, so that I could handle it and clear access to his drive way. Before I could get back to it, a distant neighbour stole it all. I’ve learnt my lesson. Act quickly!
This time I get it all up onto my truck with the assistance of my very good friend Len, who just happens to call in to visit. No such thing as a free lunch Len.
I also go to the barn and install my hydraulic crane onto the truck. I use this to lift the largest blocks up onto the truck. They must weight more than hundred kilos each, when they are freshly cut and full of water-based kinos and sap. The longest pieces will be used to fire the wood kiln, the shorter pieces will be used in the hose in the kitchen stove.
Over the hotter months, we collect all our garden prunings and pile them up, saving them up for a time like this that is cool, and damp after a good fall of rain. We had just over 25mm of rain the other day. The weather is just right for us to do a hazard reduction burn. We wait until the evening, for the temperature to fall and the humidity to rise. It only takes 20 mins for it all to reduce to ashes and a few embers. However the core of the ember pile keeps on glowing through the evening and into night. We make regular trip to the pile to check on it. Hosing water all around the site to make the ground very damp.
We have two piles to burn. One pile at each end of our 7 acre block of land. One each night, After the fire dies down and all the hard work is done we share a beer!
I get to drink my home-made, home-brew beer from a porcelain cup that was given to me by my Korean friend Hae Jin.
We are still able to pick ripe tomatoes now in June. Only just a bowl full each week now, but they are still lingering on. I’m so amazed. This is the latest that we have been able to continuously pick tomatoes. We haven’t had a frost yet. Such a strange time. We have lived here on this piece of land for over 40 years. In the 1970s we had severe frosts in May that burnt off every plant that was tender. Now we are now in June and it’s still warmish. 5 oC over-night at this time. No-where near a frost. Global warming. What global warming? Or as the Guardian Newspaper has started stating it. Climate crisis! What Climate Crisis?
Wake up everyone! Choose to only buy green power. Put solar panels on your roof if you can. Insulate your ceiling instead of turning on the air con. Wear a jumper in cooler weather. Choose energy efficient appliances when they need replacing. Many small things make a difference.
The lead article in today’s Guardian Newspaper; 12/6/19
“Australia is missing an opportunity to easily meet its emissions targets through energy efficiency measures, new research has found.Australia could cut greenhouse gas emissions halfway to its Paris agreement target, and save $7.7bna year in bills, by adopting existing global standards on household and business appliances such as hot-water heaters. The report, from the Energy Efficiency Council, found that adopting the measures used in Germany would save the average Australian household $790 a year on power bills and create 70,000 extra full-time equivalent jobs.”
One of the jobs on my very long list of jobs now that I’m back, is to make a batch of porcelain clay from my Australian materials. I have all the materials ready to go and I use the ancient one arm dough mixer that I bought 2nd hand 40 years ago. This dry-mix method is only appropriate if you have all the materials prepared in a pre-powdered state. I blend them all thoroughly for some time and then add in some suitable acidic water from the old galvanised water tank, that collects its water off the pottery roof. This water is enhanced by the addition of rotted gum tree leaves from the gutters. This composted, highly acidic material lowers the pH of the water quite a lot. This flora and fauna creates a thriving micro biome. It all helps the clay that I’m making become a little bit more plastic and slightly better to work with. And it’s free and totally natural.
When I use a blend of wet-mixed slip added to dry-mixed clay like this, I get the advantage of speed, without sacrificing too much in the way of plasticity. I am due to lay this ‘quick and dirty’ sericite blended porcelain body down to ‘age’ for a while, to get it to ‘sour’. All clays, no-matter how they are made and from what, will benefit from a relaxed period of ageing in a damp, dark, cool place for what ever time you can spare. I have a few packs of very old, hand made, single stone, porcelain that I have been mollycoddling for over a decade. What started out as wet sand, is now a quite plastic throwing body. If only you could buy time! Or make it.
I have built a new pug mill table out of my spare off-cuts of gal RHS and stainless steel sheeting from the kiln factory. I have designed it so that the pug can be extruded out over the end of the table onto the extended table, I can then fold it away again after the pugging. I set it up with a diagonal retractable brass brace that hooks into place to hold the extension horizontal when needed.
It’s a beautiful thing.
It’s hard working, reliable, rough, but acceptable. A bit like me!
Another thing that I have done since my return, is to take my crippled lap top to bits and install a new 1Tb solid state drive into the old hard drive space. It starts to work again like a new one. It’s 6 years old and by any ordinary reckoning should be pretty much dead by now. This new digital ‘heart transplant’ should give it new lease of life. It certainly seems to have.
It’s not too technically difficult, even I can manage it! But it does take me about 4 hours. Most of this time was spent in duplicating all the old hard drive data onto the new drive.
Everything that is worth doing takes time, or so it seems.
It’s not just ageing clay that takes time!
I started pickling olives before I went away. Soaking them in water, changing it every day, rinsing and changing once or twice a day for two weeks. I also cut a couple of slits into each olive, to speed up the de-bittering, by allowing the water to penetrate into the flesh easier.
Olives have a very bitter taste when harvested. This bitterness needs to be rinsed out over a couple of weeks. I taste them every few days to check how they are going. It reduces slowly, but they never seem to get past a certain level of bitterness. The next step is to start adding salt to the water to make a brine. I add 1 cup of salt to 10 cups of water. This is just enough to cover the olives, with a dinner plate on top to press them down. I change the brine everyday as well, just as with the first two weeks of water. They get salty now and still a bit bitter.
As I was going to be away for a month. I added a couple of cups of vinegar to the brine on the last change before leaving. I don’t want them to ‘go off’ while I’m away.
When I returned, one of the first things I did was to go back to rinsing the olives each night in plain water. This change of concentration draws out more of the remaining bitterness due to osmosis, from acidic/salty to clear water. It works nicely. I change the water each day for a few more days and when they taste about right, I pickle them in a brine of;
 1/2 cup salt
 1/2 cup sugar
 2 cups vinegar
 6 cups water
I heat the glass jars in the oven and simmer the lids. I make up the brine and add slices of lemon, garlic, fresh herbs from the garden, bay leaves, chillies and pepper corns and let it cool down to just warm, then pack everything into the jars and pour over the warm spiced brine. They taste all right sweet, salty, bitter, spicy, and fresh and slightly lemony, with a chewy texture.

Sericite Journal 4. Out of the fire and into the flying man (’s baggage) 

While my kiln is cooling down. I go for walk along the river, the runs behind the Museum.
Today I see a white crane stalking the shingly shallows, although he doesn’t look to be doing much business this morning. Maybe he is so full already that he is having a rest?
I also spot a black cormorant, ducking and diving. Popping up again here and there, working the deeper river pools.
Slowly a fisherman comes into view, he is strolling quite slowly up stream with his net in hand. He is working the river between the road bridge and the foot bridge. He stops to cast his net out occasionally, apparently with little or no success. I’ll put my money on the cormorant any day.
The sun is well up and I can’t see the sun. The air is just as dirty today as it was yesterday and will  be tomorrow. I imagined when I arrived here this time that it was just some intermittent phase in the air currents. I don’t remember it being this bad before, one, two, three or even 4 years ago. This is my 5th visit to work here. Miles away from the industrialised region of Seoul and it’s the worst that I’ve seen it. The air should be cleaner here. It used to be. I remember being appalled on my first visit here when I returned to Seoul to fly out. I couldn’t see the sky scrapers through the coach’s windows until I was right next to them. This is awful, I was appalled before, simply because of the contrast of country and city. I feel my chest tightening each day. Now the smog is every where. There is nowhere where it isn’t thick and grey.

I get to make another visit to the clay processing building, as there is a problem with the rock crusher that they have just acquired, 2nd hand. Apparently the electric motor starts to smoke after 20 mins of use, i have a close look at it , just from the outside. I can see that the motor is recently reconditioned, the over-spray is still evident on the motor housing and wiring. I’d say that it has burnt out the motto previously in its past life, That may be why it was for sale 2nd Hand?

I suggest t hat they do some research on other new models of this kind of machine and check out what sort of horsepower in really needs. I typed this last sentence in 10 seconds just now, but last week it took me about ten minutes to say all this is several goes at it using the translation app! Waiting for them to formulate a reply or ask another question, then I type my one fingered reply on my tiny, phone virtual key board. It takes a long time.

That’s just the way it is here with me and complex ides and a language that I can’t speak. I feel like I’m a child sometimes. I ave some complex questions that I would like to ask, but when I start to formulate the sentences. The moment has passed and I can see that i will al lot more contextual material for this all to makes one sort of sense. So i give up and wait for another occasion. They must think that I’m stupid sometimes.

It’s a fantastic resource to have available to them to efficiently process their own sericite porcelain from the excellent, but slow, ‘wet-method’ from ball milled slip, filter press and vacuum pugmill.

Colour me ‘Venco-Green’ with clay processing envy!
I the afternoon Mr Jung takes me for a ride, up to the South/North Korean border. There is a lookout post where you can see over the no-mans-land. The road takes us to the east of here through a volcanic crater that is called the ‘Punch bowl’. It is intensively farmed due to the rich volcanic soil within the extinct volcanic crater. It reminds me of the Rutherglen region of Northern Victoria. Great wines are grown in that rich soil and concentrated micro climate.
The lookout post is on a high ridge that is part of the caldera’s edge. I was not allowed to take any photographs of the Northern side of the border, facing the other way, as it is forbidden, and the solder/sentries on duty at their posts make sure of it.
I can report that there is absolutely nothing to be seen. Is this because there is so little development in the North? Perhaps. But I am skeptical. I think it more likely that The North, knowing that there is a clear view into their territory from this high place, have made sure that there is absolutely nothing to be seen.
Imagine the image below with no roads, no farms, no power lines, no clearing, no development of any kind. Just the green rolling hills, going on into the distance. That’s what you can see of the North from here.

 

 Last year when I was here for the Moon Jar conference, the streets in the village were being dug up, deep trenches dug and piping installed. The workers were so very efficient. We were amazed at the time how quickly the work was completed. 3 days for each street, excavated, piping installed, road rebuilt to as-new standard. Fantastic. So little inconvenience to everyone.
I wondered at the time what was being installed.
Now on my return, I can see that every home now has a reticulated LP Gas line and meter next to their house. The homes that are also restaurants, also have a small storage tank as well. I’m assuming that this is to allow peak load at the lunch time and dinner time rush hour, so that they don’t drain the pressure from the street.
This little village is miles from anywhere and a very long way away from Seoul, but the government is committed to reducing the air pollution. One way is the stop the use of coal briquettes being burnt in the countryside where this old anachronism is still in common use.
Coal is a very dirty fuel at the best of times, and the use of crude briquettes in an up draught stove is a real 3rd world solution to cooking and many thousands of women die of respiratory disease each year. Korea is a very technically advanced nation. They built my electric car for me for example. However, way out here in the countryside. Miles from anywhere. Some of the households are still using coal, as they have for 100 years. It’s a credit to the current government that they have funded this development in such a remote place.
I can’t imagine that the gas is pumped all the way from Seoul. It’s just too far to imagine. I assume that the liquid, compressed gas is trucked here from the refinery, to some local depot, where it is stored, evaporated and reticulated in the local network. I’m impressed, as I am with much that is happening here. They still need to stop building and selling diesel engined vehicles though.

As I walk down the street today I can see that one house is still using the dirty coal briquettes, as the spent bisque fired, low quality, circular coal briquettes are stacked up out side the dwelling. I know that some of these spent fuel blocks are crushed and used as a fertiliser. I’ve seen the remnants of them scattered through some of the vegetable patches.
I remember reading an old book back in the 70’s, called ‘Farmers of Forty Centuries’. It was a really interesting book that described the life of farmers of Asia, in China, Japan and Korea, their lives and techniques. I say that it was an old book, because it is! It was published in 1911. There was a chapter about digging silty clay out of the irrigation channels and making mud bricks from it. The bricks were made into a ‘Kang’, a wood fired stove that has an extended horizontal flue area that doubles as a warmed bed base at night after dinner.
After several years, the ‘Kang’ is demolished and recycled. The mud bricks, wood ash and whatever other minerals have been absorbed by the bricks are all crushed to powder and spread through the vegetable garden as a fertiliser! 110 years later, the old technique is still practised by some of the older residents of this village.
The other thing that I see that is different in the village is the new solar powered telephone. This is very new and quite impressive. I’m mostly impressed by the fact that the phones here aren’t  vandalised and still work. I must say that I’ve never seem anyone in there using it, as every young person in the village seems to own a mobile and the signal is very good here. There is also a new electric car charger in the car park!
The other thing that is a huge difference here is the construction of the new Museum extension. It is HUGE!
It looks to be about 3 or 4 times bigger than the old single room, exhibition area and offices building. The existing space was very cleverly divided into a lot of smaller ‘rooms’ using divisions to visually break up the big single volume, into more intimate spaces, each with a small specialised minor subject, display or video, used to explain some particular part of the amazing local history of the discovery and development of the single stone sericite porcelain story, that is endemic to this place.
The new building will occupy the entire length of the grounds from the road frontage, right down the side of the old Museum building and all the way down the side of the site, to the river-frontage walkway at the rear.

The new Museum extension will apparently consist of three new exhibition areas. Each with a particular theme. One of them will be a flexible space for a changing series of contemporary themed shows. One will have a small space for a glass case with my contributions to the continuing story of the Yanggu/Bangsan unique sericite porcelain history.
I look forward to getting to see it all finished on my next visit here.
Friday comes around soon enough and I have an appointment with the governor of the local government area or Province in his offices in the city.  Mr Jung has it all arranged. He has made the appointment a couple of weeks ago, when I first arrived and presented him with my 3 porcelain bowls made from the ‘borrowed’ sericite stones of my last visit, now all glazed with my local kangaroo blue opalescent glaze and returned to their birthplace in an enhanced form. The Premier seems to have been suitably impressed by the gift of my cultural amalgam of Australian/Korean porcelain culture.  As a way of promoting the Museum and gaining some exposure for his project, both with the political ‘machine’ of local government, who are funding the new Museum expansion, but also in the papers for local residential exposure/consumption. Mr Jung is always working to promote his life’s work and interest in sericite porcelain. Mr Jung and I are possibly the only two men in the world just now who are practising this ancient art form.
We meet in the Premiers Office. Myself, Mr Jung, Myeongki my translator and several local government minders. We are ushered into the Premiers private office, with its loverly, large round table and very plush leather lounge chairs. The official photographers are there and capture the moment for the press release. Everyone benefits from this meeting.
The Premier will be in the press showing that he is supporting the arts. Mr Jung can show that there is international recognition of the importance of his Museum. And I get to realise that I am under-dressed for a top level political meeting! After a bit of small talk, the Premier reaches out and holds my hand for the second photo-shoot.
I present him with the pots and a copy of my ‘5 Stones’ book, recently translated into Korean. He is polite and is well briefed. He says thank you for the important cultural gift, that now links our two countries. He tells me that he is impressed. They are beautiful. He also understands that I have developed a kiln design that is smaller, cleaner, more fuel efficient and less polluting than the traditional Korea wood fired kiln. I reply that I think that this is true. I have been working on this technology for a several decades now and the design is becoming quite sophisticated.
He replies that he thinks that Korea must have this technology, and goes on to express the opinion that they are intent on cleaning up their environment and doing what they can to become more environmentally friendly. Mr Jung has already made a proposal to build such a kiln at the Beakto Porcelain Village in Bangsan. The Premier says that he thinks that they should fund a project like this and also have the new wood firing book translated into Korean as well. I’m a bit shocked, is it that easy? Apparently it is.  I wasn’t expecting that!
We have tea and the locals discuss something, all in detail in Korean, that my translator describes to me in small whispered chunks, as it really doesn’t actually involve me at all. It’s secret-mens-political-business that involves the realities of the local government political/economic system. The meeting ends with much hand shaking, smiles and bowing. We leave and everyone seems happy with the result.
It appears that this was just the event to push the new kiln site and kiln building proposal over the political line. Apparently the combined project will be fully funded now, as well as the book. Is it really that easy? I think that there may have been a lot of lobbying going on for a long time behind the scenes? This may just be a ‘way-marker’ point. I mention this to my translator out in the street, adding that in Australia, politicians are renown for saying one thing in public, while doing another, totally different thing behind the scenes. She nods and agrees, politics is probably the same all over the world? Inferring that we will have to wait and see.
My Jung has managed to get the 6 million dollars to build the new Museum extension. He’s an impressive man. Maybe this much smaller, micro-project will happen too?
I cast my mind back 4 or 5 years to my first meeting with Mr Jung in 2015? with Ms Kang as my interpreter at that time. There were two architects invited in to see my presentation to Mr Jung about my research. I can only guess now, that they were there working on the new Museum plans at that time? That would make sense, as these large projects take a long time frame to evolve, develop, mature and eventuate.
The next day, the kiln is cool and my work comes out. I get to see not only my pots, but also the clay and glaze tests that I made from Mr Jung’s new glaze stone deposit from the hill behind his house.
My pots are mostly good. A few have minor faults, but most are good. A few are great, beautiful clear, rich, translucent examples of sericite at its best. I could have applied the glaze a little thicker to get a richer colour. I did give some of my pieces a second dip in the glaze to hopefully get a better result, but second dipping can lead to problems and  I didn’t want to loose all my work from a preventable problem, so just did half. These turned out the best, and now I wish that I had been brave enough to have done them all. My intuition was correct, but my caution was justified, it’s a good outcome. In the worst case scenario I could have lost all my work. So it’s all good.
It’s very interesting to me how the different sericite bodies influence the same glaze in the same firing to come out looking so different. All local sericite porcelains, each showing their own individual character.
 The glaze test results are very good. The new stone produces a beautiful satin blue celadon style glaze at 1270oC in reduction. It’s really good. I could use a glaze like this with pride on my work.
Most of the staff are there to see the unpacking, but Mr Jung has to go out to a meeting somewhere, so doesn’t stick around.
I start to explain to some of the resident researchers and a few of the staff just what I was doing with the glaze grid tile. No-one seems to have seen a grid tile before. It seems that they don’t learn much glaze chemistry in the art schools any more. Just like in Australia and the UK.
Janine and I were invited to do some work for the new ‘Clay College’ in Stoke on Trent last year. Clay College is a fantastic initiative. It’s an attempt to re-start a new hands-on ceramics course for potters in the UK, as it seems that all the universities that once taught ceramics have all been converted to ‘design’ schools, where students ‘design’ objects that get made somewhere else, by someone else, like China, or pumped out from a 3D printer?
I explain that the function of this test is to analyse the stone to find out its chemical analysis in % oxide composition. This sort of thing has usually to be done at great expense in a university chemistry lab using electron microscopes or similar.
I explain that I have developed a simple technique for achieving this using just a simple set of scales and a few ingredients.
They had all watched me make the test a few days ago. Now they see the outcome. I look at the colour and melt activity of the test tile and compare it to my data base of known results. I can quickly ascertain the oxide analysis. From there I can use ‘Segar Formula’ to adjust the glaze stone to make it do a number of different things.
I see that every one is very quiet. Eventually someone asks “what is that formula?”. No one has even heard of chemical formula for glaze calculation.  It seems that the only glazing that’s taught here is how to buy a glaze from the pottery supply shop catalogue. We are at that point here in Australia now. Nothing difficult or technical is being taught.
I give a quick class in glaze calculation. One of the older students tells me that he was taught something like that 20 years ago, but wasn’t paying attention and couldn’t see any reason to learn it at the time. Could I go through that all again slowly please.
I do and they slowly get the drift of the exercise. Not the Segar Formula part, but the compound line-blend test tile exercise. They really like the glaze quality of the result and the ease of ascertaining that result with just one test using a totally unknown stone.
They ask me how I learnt how to do this? Who told me that this was possible. I tell them that it is my own invention. I developed this testing technique during my PhD studies, as I was focussed on using local stones to make local porcelain. More or less trying to achieve in a few years what you have been doing here for 700 years!
I fettle and grind my pots ready to go. I pack them in 3 equal lots and wrap them very well in bubble wrap. One batch goes into my suitcase wrapped again in my clothing. A second lot is slid into my back pack. It just fits and the last group are packed into a cardboard box and taped up. I assume that I will have to pay excess baggage fees to get them onto the plane.
On the last day before I leave Bangsan, Mr Jung takes me up to the Baekto Porcelain village to say good bye to the resident researchers, Mr Jung wants to show me something. The money has come through as promised and work has begun on the new kiln shed. It looks like the project will be going to happen a lot faster than I could have imagined. The Premier is a man of his word.
The site has been a excavated and men are at work setting up formwork ready to cast the concrete footings for the new kiln shed. They have to dig down 1.8 metres to get down below the frost line where the ground freezes during winter. Here that is very deep as the temperature drops to below minus -30oC in winter. The frozen soil will expand and cause the ground and everything on it to crack unless the site is well prepared like this.
Mr Jung explains where my kiln will go in this huge shed. Over on the left hand side, there will be at least one other kiln in here and possibly two, in years to come. One of them is going to be a 5 chamber, traditional climbing kiln. A juxtaposition of the old and new in wood firing techniques.
Mr Jung missed my glaze lesson and asks Daewoong to ask me if I can send him my PhD thesis? I reply that of course I will be pleased to do so, but it is 120,000 words in English and academic English at that. Maybe I should just send him the glaze calculation part about rock glazes? As it happens I just happen to have a book called ‘Rock Glazes and Geology for potters’. I’ll post him a copy. I can see yet another translation project coming along in the future?
This may be my last attempt at a travelers’ tale from Korea.
I considder myself just so lucky to have met such incredibly nice, creative and supportive poeple here.
Best wishes
Steve

Bruised Butt Cheek Bones

Over summer we don’t go far. We stick around the house, just in case of bush fires. We concentrate on cleaning the gutters, servicing the fire pumps and working around the house and in the garden. It’s a very productive time of year in the vegetable garden with so much produce to harvest, preserve, cook, dry, bottle, vacuum seal. In March the fire danger is mostly over and we can relax and catch up on some music concerts and the Writers Festival.

We returned from Writes Week and WOMAD to find the garden gone mad and a lot of work needed to be done to get it all sorted out, cleaned up, weeded, mown, whipper snipped and mulched. I have it back in good shape now and most of the winter seeds and seedlings are planted for the approaching cold weather. Over summer, we don’t get into the pottery very much. Instead, it’s a time to use the heat for making clay, crushing rocks and ball milling porcelain stone, then drying that porcelain slip.

Now in April, we can start to think about firing the wood fired kiln again. The summer fire bans will soon be over and we can fire the wood kiln without restriction. We have been doing some firings. I have been firing our solar-powered electric kiln and reducing it with a few hundred grams of LP gas to get the reduced colours.

We have been back in the pottery for the past few weeks and started throwing again. I must say that the first couple of full days on the hard wooden seat of the “Leach” style wooden kick wheel leaves me with a couple of sore butt-cheek bones. I don’t think that they are bruised, but they sure get very tender after that first full day. It seems to take a week or so for them to toughen-up. Then I don’t notice it again till this time next year.

IMG_4719

I bought some sericite stones back with me from my trips to the UK and Korea last year. These stones are now processed and aged sufficiently to be able to consider throwing them. I always think that this time it will be different. This time I will be able to throw something better out of this wet gravel. I can’t! Every time it’s the same, I start off so optimistic. I’m sure I will be better at it. I’m Not! The stuff is just wet rock dust, I shouldn’t be surprised. But I am!

I struggle with it as it is and refrain from adding any bentonite into the mix. I should just get over it and give in, but I really want to make something authentic. Something that has some meaning in this post-truth, bare-faced lying, compromised, new world order of shallow poseurs, where everything is The Image and The Selfie. I know that what I’m living here has no value to anyone else but me, I persist. It’s the life I’ve chosen. It’s a challenge to make a nice pot from these original porcelain stones. Picked from the ground, in-situ by my very own hands, carted off in my back-pack and then brought home here and processed in my own equipment. Maybe if I aged these bodies for a decade, then it would be easier? I’m certain that it would. I have already done those tests a lot earlier in my career. I know it works. However, I’m not too sure that I still have a decade left in me. I strike a compromise and decide to make some very small beakers and some coffee cups. Now, I can almost manage these OK.

IMG_4693 IMG_4718

Last year, my friend Len and I imported a tonne of Chinese sericite. I have been going to China each year and renting studio space, making work, getting it fired on site – with mixed results, and carrying the best pots back in my hand luggage, to show at Watters Gallery and elsewhere.

Last year I felt so guilty about my carbon miles, making work in this way that I decided to buy the milled sericite in bulk and ship it here, This way I can stay at home and the clay can log up the carbon miles. I feel that it ought to be less damaging environmentally to ship a tonne of milled sericite stone by sea, than fly my meagre 80 kgs to and from China in a plane. Any way, I buy my $400 worth of carbon credits, just the same each year, to appease my conscience for my carbon crimes.

Buying the material in bulk sounded like a good idea at the time, but like all the best laid plans…. The stuff that arrived was totally different from what we had thought that we had bought, or ordered at least. Back in the beginning, we purchased a sample of the sericite and tested it. It was difficult to work with, but OK. White, semi-plastic, just. It fired white and translucent. We ordered a tonne of that thank you very much!

What arrived was grey, short, very soft and soggy, difficult to throw with and split and cracked in drying. Totally different material. I couldn’t see us shipping it back. We had already paid in advance. I had to make it work somehow. I tried throwing it in the usual way that I have learnt to work, but I lost over 90% of my pieces. I took a while, but I thought it over and came up with what I thought was a cunning plan. I thought about the ancient Chinese and how they coped with the short-comings of their early sericite porcelains. This was just the same, only re-located over 600 years in time and 12,000 kilometres in distance. The old tried and true answers are usually the best.

I tried a small batch in a blend with something that I thought had exactly the right characteristics. Hey presto. I now have a way of making a unique white, translucent, Chinese sericite based, porcelain of my own making. It’s one answer. It works for me.

IMG_4661 IMG_4662

What I still find perplexing and inexplicable, is that Len has no trouble in making perfectly fine pots out of his batch of this stuff with no problems, while I struggle. Obviously this sericite stuff responds to the hands of a true master craftsman but dumbfounds and perplexes a blowhard wannabe like me.

Our New Intern from Korea

We have a new intern working with us this January. Our visitor is Ms. Kang from Korea. She has come here to experience our sustainable approach to life and our ceramic work.

We have been working together crushing and grinding porcelain clay body and glazes from local rocks, throwing pots, working in the vegetable garden growing our food, cooking the food that we harvest and doing a little bit of sightseeing as well. The three of us have been doing some tourist activities together, like a trip to Sydney with a ferry ride on the harbour, and a trip to the local National Park and the south coast beaches.

Ms. Kang has been learning to use our foot-powered ‘Leach-style’ kick wheels.  We have just finished making sufficient clay work today to fill the solar powered electric kiln for a bisque firing. Last week we calcined some local white granite rocks, to make our local blue celadon/guan glaze.

Pretty-much life as usual, but with a hard-working and dedicated student-guest.
