We have hit the ground running in this first week of the new year. I still have to build the wood fired kin so that I can get on with my work and research.
Before I can build the new wood fired kiln, I need to build a roof to keep the new kiln dry and weather proof.
We have a beautiful court yard area that only needs a skillion roof over it. I spent the first couple of days of this week making the portal brackets that I need to join all the rolled steel purlins for the roof.
I had half a sheet of 3mm gal steel, so was able to make all my own brackets from this. Cut and folded into useful custom brackets. Then pre-drilled to take the 12 mm. high tensile gal bolts. I drilled 200 holes on Tuesday with my hand held battery drill. I spent quite some time sharpening drill bits to keep them all sharp as the day wore on.
Once the 12mm. bolts are in and tightened, it prevents the various members from parting company. Then there are 8 to 10 ‘tek’ screws to be drilled in around the bolts to stop any lateral movement or swivelling around the bolts. It’s a very quick and elegant system to secure the rolled steel purlins together with great structural stability. There are 8 bolts and 24 tek screws holding each triangular corner plate together.
By fabricating all the crucial parts myself, all I need to purchase are the long, rolled steel purlins, as these are 6 or 8 metres long, and too big for me to fold myself in my workshop. Everything else is scrounged, recycled, repurposed or home made on site. We are even using some of the hundreds of metal screws that Janine picked up around the building site after the contractors erected the original shed frame.
On Wednesday, my friend Warren turned up for a 3 day stint. We dug the footings and cast the ‘H’ section posts in concrete. I had pre-cut and stacked the posts ready to go into the ground. On Thursday, the cement had set and we were able to bolt on the cross-beams and triangulate the structure with knee braces, making it free standing and structurally stable.
Friday saw us screw on the ‘top hat’ rafters, or roofing battens, and then finally screw on the galvanised iron roofing and polycarbonate sky-light sheeting. Not too bad for a couple of amateurs in 3 days. What was remarkable was that all this was done in the pouring rain. It seems that all the negatives of working on ladders, at height, when over 69 years old, with power tools, in the rain, on slippery steel. These all seem to cancel each other out and the result is all positive. A finished, metal-framed, kiln shed roof with skylights and excellent ventilation.
I wrapped the power tools in a plastic bag to keep the rain out of the electrics. Just had the drill bit sticking out of the cut-off corner of the bag. It worked really well.
This coming week, the second week of the new year, We will be picking up and carting the paving stones back from their storage stacks post-fire and re-laying them in the courtyard in preparation for the bricklaying of the wood kiln. I really need the wood fired kiln built and fired as soon as possible, as I need to get my exhibition commitments under way.
Each week brings us closer to the completion of our new workshop. Nothing is ever finished, Nothing last for ever and nothing is perfect.
We have been busy – always busy, but we have managed to organise a few impromptu get-together parties with our neighbours, the ‘creatives’ of Balmoral Village. We have all been fire-affected in some way, some more than others, but we have survived and we are looking forward. We organised these dinners to ‘catch-up’, share news and ideas, but mostly to take some time out to celebrate each others company. We cleared out the big central room in the new pottery because it has beautiful light and plenty of space. We can fit 10 at the big glazing bench, 11 or even 12 at a pinch. It’s been very enjoyable to share time and food in this way. Although just as much work preparing and then washing up and cleaning, then setting everything back in its place, as it is building the space.
This week I booked the electric car in for its third service. It been amazing driving around these past 3 years on sunshine. It’s a plug-in hybrid, so it does have a petrol engine in there as well as the battery and electric motor. We can do all our local running around entirely on sunshine, but every now and then we go a little farther afield and we come home on petrol. When the battery is fully charged and the fuel tank is full, it has a range of over 1100 kms. However since that first fill 3 years ago, we have not filled the tank since, as it took us the best part of half a year to use the fuel up. It’s not good to store petrol for so long. It can go gummy, or ‘off’. Since then we have only put $20 in the car every 3 months or so, even that is a bit long, but it seems mean to pull into the service station and only put $5 in each month. We seem to have settled into some sort of routine of going to the petrol station quarterly.
We charge the car and our Tesla battery from our solar panels on the shed roof. We produce a maximum of 5.3 kW of electricity on the best sunny days, but much less in overcast and rainy weather. However, this size of Solar PV installation is enough to charge our car, run our house and pottery, even fire the electric kiln, AND we still have some excess to sell to the grid on an average day. These days, we earn over $1000 per year, (it used to be double that) while living, driving and firing our kiln for free. We went solar in 2007. We haven’t paid an electricity bill since. The system has well and truely paid itself off over that time. Interestingly, as more and more people connect SolarPV to the grid, the price that the utility pays us for our power has progressively gone down. Years ago, we used to get 60c or 70c kWh. Over the past 4 years the price that we get has dropped from 21 cents per kW/hr, down to 19, then 17 and now 10 cents. I can see it being 7 or even 5c next year. It’s great that more and more people are going solar. If not fully, like we have, but every little bit helps get more coal power and its pollution out of the system.We didn’t go solar to make money, but it has turned out that we have. We went solar to try and minimise our reliance on the fossil fuel economy. That has certainly worked out very well. Our power bill tells the story.
We consume less than 1 kWh per day on average over the year. We have spent our life here honing our self-reliant skills to consume everything minimally. Our 0.91kWh is about 1.5% of the ‘average’ 2 person household, yet we live in a very old house, (128 years old) not a new solar passive one, and don’t ‘want’ for anything. It can be done.
The utility charges us about $1 per day to be connected to the grid. Their ‘access’ charge. This has been steadily increasing over the years, while the feed-in tariff has been gradually dropping. At the moment we pay $1 a day to be connected to earn $3 per day. I can see a time when this balance reverses. I guess that’s when we start to think about the 2nd battery and disconnect from the grid. I’ve read that this is called the death spiral of the electricity industry, but I can’t see it happening, as it takes a lot of effort and planning to live a life of minimal consumption like we do.
All this rain has the garden growing very well. I’ve been putting in a lot of effort in the veggie patch recently. It’s looking more loved now and providing us with all our green food. The warmer weather combined with the rain has the grass growing it’s head off. Janine and I spent half a day each yesterday mowing to keep it under control. We haven’t had to mow this much for years. All the greenery is very soothing on the eyes. All in all, the COVID plague aside, it’s looking like a pretty rosy year ahead.
We have just had our first Open Studio weekend. It was good. Not too busy, just right. We had an influx on Saturday morning with half a dozen cars in the first hour. We even had a queue at the wrapping table for a short time. but after that it settled down to just one car after another until lunch time and then a long spell of quiet. In the afternoon we had several more visitors spread out more or less evenly until just after 3pm when it stopped.
We were lucky that there was a big function on at Sturt Workshops in Mittagong all day Saturday, so we picked up a few car loads of visitors that called in here on the way past, coming from Sydney and going to Sturt.
We have had only 4 stoneware glaze firings in the 3rd hand gas kiln that I bought back after 26 years out in the wild. It’s now back in captivity and working well.
Sunday was quieter, but still good. We had the same lull in the middle of the day but a much quieter afternoon. It was a great start to this 4th pottery iteration after loosing the first 3 to fires, we have been a lot more cautious about what sort of garden and just how much foliage we can accept near our house and workshop. As this new 4th pottery is almost entirely made of steel, it is a lot less flammable. Steel building can still be ruined by intense fire – they bend and collapse in intense heat. So that is why we have decided to build this new studio in the middle of our block well away from any bush. I have already plumbed the building with fire fighting sprinkler lines. Although as it is so wet they year. I haven’t got around to fitting the sprinklers yet.
I decided to spend those couple of days in the pottery making work for the sale. Everything in it’s own time.
We almost sold out of Janines painted unomi beakers and inlaid lidded boxes, as well as my breakfast bowls.
So on Monday morning we were both back on the wheel making new stock for the up-coming December Open Studio weekends as we have elected to be part of the Southern Highlands ‘Pop-up’ Artists Open Studios on the first two weekends on December, – 4th and 5th, then the 11th and 12th.

Yesterday we had all three kilns firing at once. A bisque in the little electric kiln, a stoneware reduction glaze in the big gas kiln and another stoneware reduction firing going on in the old relocatable mini wood fired kiln. I recovered it from the ashes of the fire. As it was built from a stainless steel monocoque frame with insulation brick lining, it mostly survived the fire, because it was stored out on the verandah and didn’t get too badly burnt. It just needed some cosmetic TLC on the frame and a new set of castor wheels. Lucky!
It was designed and built as a possible dual fuel kiln to be fired with either wood or LP gas from BBQ bottles. However I had never fitted it with burners and only fired it with wood previously. Now is the time to finish fitting it out with burners. I spent a day making shiny new burners and gal steel mountings. I chose to only pack and fire the bottom half of the kiln , as it is designed to be in two sections. A bottom half with the fire box opening and burner holes – which ever is chosen to be used. Then a top half composed of a removable ceramic fibre ring and lid. The ring can be removed and the lid placed on the base section to make a smaller half sized kiln. Which is what I did yesterday. As it was the first test firing of the kiln, I thought it best to go small for a first firing.
After an initial tweaking and tuning, It worked perfectly and fired to stoneware in reduction easily in 2 1/2 hrs. using less than one 9kg bottle of BBQ gas. I had 2 set up ready with a change over switch just in case, but the 2nd bottle wasn’t needed. I also set them up in a tub of water that can be warmed. In this way I can fire them to dead empty without them freezing. But none of this was necessary yesterday.
I’m a bit more confident about our local rock glazes now after 3 rounds of test firings. The hares fur/teadust tenmoku is a little more stable.
Both Janine and I have been investigating the use of colours over tenmoku.
and I have managed to stabilise the local Balmoral dirty feldspathic stone and wood ash opalescent Jun glaze.
Janine has made some slip decorated lidded boxes.
The stone fruit orchard is looking great after a wet start to the spring season and everything is green and luscious.
The almond grove is also very lush and green. All these mature almond trees were burnt and transplanted into this area that was formally a native garden. We have decided to keep the more flammable native bush at a much safer distance from the house now.
The pottery will be open this coming weekend, the 13th and 14th of November as part of the Australian Ceramics Assn. Open Studios weekend that will operate nationally. We will be open in conjunction with Megan Patey in Colo Vale. Megan makes beautiful Majolica and Smoked Arab lustre.

Janine and I will be also open on the first two weekends in December and the Southern Highlands Artists Pop-Up Open Studios group.
We will be open on the 4th/5th and in conjunction with Sandy Lockwood, on the 11th/12th of December.
We look forward to being able to show you around the new pottery on one of these 6 days.
We will be following the government recommended COVID19 safety protocols. So please come if you are double vaccinated and have your vaccination certificate. There is our Service NSW, QR code poster on the door for login
We have a covid-safe plan that includes keeping the space very well ventilated and limiting numbers to 4 sq.m. per person.
Please don’t bring dogs, as we have recently had both wood ducks and brown ducks hatching clutches of little ducklings that waddle all around the property with their parents feeding on the lush grass. These are timid wild animals and we have no control over where they wander. So please keep a respectful distance if you are walking around the garden.
Dear Friends, We will be opening our pottery on the weekend of 13th and 14th of November. We are informed that on the 1st of November, the state will be opening up to allow people from the Greater Sydney Region to travel to the regions like ours in the Southern Highlands. We have joined the Open Studio Weekend organised by the Australian Ceramics Assn. and accordingly, we will be open from 10 am to 4.00 pm on both Saturday 13th Nov. and Sunday 14th Nov. We are looking forward to seeing our friends again after such a long time in lock down.
We must remind you all that we will be observing strict Government COVID safe protocols.
Please don’t come unless you are double immunised, and have a vaccine certificate to show us.
We will need to see your vaccination certificate before you can come in and there will be a strict 4 Sq. M. rule applied. That’s 7 people max. in the gallery. Although I can’t imagine that we will get more than 7 people all day, never mind all at one time 🙂 We will have all the doors and windows open for good ventilation and to keep the CO2 levels down to around 450 ppm. As this is considered good practice to minimise the chances of infection. We won’t have a lot of work fired and for sale by that time, as we have only now just had our first stoneware reduction glaze firing full of glaze tests. I have been very busy working on the 3 local igneous rocks that I could collect within 5 km of our home here, or near the supermarket and Post Office on our once a week shopping excursion. That has limited my choices, but it’s a challenge to make the best I can out of what I have available in my immediate vicinity.
Its shaping up to look like we can make a tenmoku and tea dust glazes from the Hill Top basalt found in the next village. A green celadon from some washed felspathic gutter sand, A pale blue celadon, a yellow matt glaze, Blue/yellow mottled glaze, also made from the local ‘Living Waters’ Basalt intrusion, and a pink matt glaze made from the sericite porcelain body. As well as something resembling a pink/orange shino style of glaze made from the Balmoral dirty felspathic igneous stone. Nothing special, but a workable mix to get us started. As long as you are double vaxed, We’d love to see you here at some stage, once we are all allowed to travel inter-regionally. Even if there is only a small selection of our our work on the shelves, we welcome you to call in and see the new shed. I’ll be pleased to give you a tour of the Workshop, Pottery studio and Gallery, as well as the raw material processing facilities that we are in the midst of developing – for those so inclined.
We will probably also be open from then on, each weekend, through until Xmas, but please ring beforehand, just to make sure that we are in and open, and not out doing shopping.
Janine made up our first bucket of glaze. She mixed up a 5 kg bucket of Leach’s Cone 8 glaze. We have used this glaze all our life. It is the reliable go-to glaze for testing all our clay bodies. A basic and reliable, no frills glaze that fits right in the middle of the spectrum. A great way to compare the various different clay bodies glaze fit characteristics in our first few firings, which will be nearly all tests.
It can also be an extremely beautiful glaze, a pearly, creamy white, surface. But this is only really true if it is fired just to cone 8 only and not higher. We also ball mill the glaze batch for a little while to get all the particles well mixed. Not too long, otherwise the already finely milled felspar granules will start to break down, releasing its alkalis into solution. Felspar does not have a chemically robust structure, so care is advised when ball milling rocks for glazing. To avoid this damage, I usually ball mill my stones dry after putting them through the rock crushers. I can then store the powder for use in making clay body or glazes, weighing them out accurately dry before wetting them down. The alkali is less likely to be released during dry milling.
I’m not trained or qualified in any way to do with mineral processing, but I have worked with locally found stones for my glazes for the past 47 years. Everything that I have learnt is self taught. I built my first ball mill in 1974. The first year after I graduated and I have built a few more since then. I will probably make another one in the coming years, when time permits. I have always kept a ball mill log to track my ball mill usage. I kept a record of what was milled, for how long and how much was in the mill, wet or dry milling and the date that I milled it, as well as any recipe involved. I lost that log book and all my other glaze recipe books etc. in the fire. Just as I did in the first and 2nd fires. I had two copies of my glaze recipe books, one in each building, but they both burnt down! I can remember that my most recent milling log, kept since 1984, I had clicked up over more than 1,000 hours of milling since then. but the exact number escapes me now. Somewhere around 1050 hours? With an average milling time of 2 to 3 hours, This is about 500 uses of that last mill. Thats a lot of hours of loading, unloading and washing out.
My friends have sourced some 2nd hand ball milling machines for me. Len Smith is always on the digital lookout for me for bits of equipment. He is so fantastically resourceful! He told me about a deceased estate of a potter. I turned up (before lock-down) and was lucky to buy what appears to be a locally made copy of a Shimpo ball mill roller and two 1 gallon, Chinese made porcelain jars. One was broken on the shoulder near the locking stud and the other has a brittle, seized rubber ring seal. Was able to prize the stuck lid off with a chisel. They both need some work. But I was lucky to get them. I made a new silicon rubber seal for the seized and a flat rubber washer type of seal for the other.
I vaselined the ground porcelain jar rim, then extruded a thick silicone rubber ring around the lid and placed it on the jar overnight to set.
This has created a new, soft and springy rubber seal that will keep it going for another 30 years.
My friend Simon Bowley, just gave me his 3rd hand Shimpo mill roller and a beautiful 15 litre Chinese jar. It has the brass wing nut and brass washers missing to secure the lid. This gadget was stored in an old shed for some years, and I’m not too sure if it has ever been used very much. As it still had the paper label from the supplier (Walkers) glued to the outside of the jar. This started to wear off as soon as I used it.
I made a couple of brass washers from the ‘hole’ pieces that I cut from the pottery sink splash-back to get the water pipes into the shed.
I hadn’t thrown them out, as I thought that they might just turn out to be useful some day. A good piece of thick brass like that, 6mm thick is too good to throw away! They came out of the hole saw pretty rough, but I was able to file them down to a smoother finish and drill out the centre hole to a clearance on 3/8″ BSW thread and they work a treat. Not many potters have the luxury of solid 6mm brass washers on their mill jar.
Len also located a very small ball mill unit in Melbourne that wasn’t being used and was able to be donated to me as a bush fire victim. It looked as though it had hardly ever seen the light of day. It came with 2 beautiful Daulton porcelain jars of about I gallon, or 4 litres, and a plastic bucket of small milling media to suit. The jars had some remnant brown dust in them, but looked as though they hadn’t been used very much.
When I tested the small mill roller with one of its Daulton jars loaded with balls and water to clean the mill. I found that the motor overheated and stopped after 25 mins. I can see why this machine wasn’t used very much. It doesn’t work! 30 mins is only long enough to do a bit of blunging, but a couple litres isn’t enough to achieve much. I will need to change the motor for a larger/stronger one. These Daulton jars will fit on the smaller end of Simons mill roller, so I can use them in this way.
My friend Tony Flynn gave me his shimpo potters wheel a few months ago, He also gave me a tiny 1 litre porcelain jar. This could be useful for milling pigments. I tried it on the RMIT roller the next day and it was small enough and light enough not to over heat the motor. It got too hot to touch, but didn’t trip the overload switch. so this will be a useful combination for small batches of pigment.
So now I have a 3 different jar roller mechanisms and by mixing and matching the different jars, I can use the Daulton jars on Simons roller, Tony’s jar on the small roller, Simons big jar on his roller and one of the smaller Chinese jars on the deceased estate roller.
Most of the jars needed new rubber seals. I had already been to the tyre business in Bowral and asked for a punctured inner tube from their rubbish bin, so I was prepared.
All the jars needed to be washed out and cleaned, then filling with balls and water and run for an hour or so the get the surface of the balls and mill all clean and fresh to start work. After milling like this the water turns cloudy, so the balls are rinsed in 2 buckets of fresh water, then placed in a plastic garden sieve to drain and dry out.
The volume of all these small jars added together just about equals the one bigger 25 litre jar that i used to own. The big difference is that to load all 5 seperate jars, run them on 3 different machines and then clean them is a lot of extra time and labour. But at least I can get some stones milled and local rock glazes made to get us going.
I stopped off at a few local sites on the way to the supermarket a few days ago. So I have a few bags of stones to work on. The next step will be to get the rock crushers going. The roller mill is still in pieces and needs some TLC
I have now installed the double walled, stainless steel flue on my newly acquired 2nd hand kiln that I built and sold 26 years ago and have now bought back. I was able to buy the flue system parts, even during lock down, as I still have my old account with the company that makes the parts.
I had told the company that I was closing the account back in 2019, as I had arranged to sell the kiln company to my friend Andy. I even took Andy to meet the owners of all the companies that I did business with, and introduced him as the new owner. Regrettably, the fire burnt us out just 2 weeks before the sale was to be completed. So we had nothing to sell.
I rang the company this year and told them the sad tale and asked if I could re-establish the account , but with a new name – Steve Harrison. They agreed and the parts were sent by courier, no new paper work. They trusted me. After all, we had been doing business together for close to 40 years. I have re-activated all of my former accounts now to buy parts to re-build. In every case they agreed to give me my account back with a change of name to my name with no paper work involved. They all know me well enough. Trust is a beautiful thing. I appreciate it. But after more than 40 years of trading with them, I sort of expect it. After all, my account number with one supplier is 001 . Their first customer to open an account!
The new rule will be; No step ladder work after 70! I just need to get this done.
To comply with the Australian Standards for a kiln located indoors. I also had to make a couple of air vents. One at floor level and another at ceiling height to get good ventilation into the room.
The floor level vent is a wide and low format, louvered, and is screened with 16 gauge stainless steel mesh inside and out.
The upper level vent is of the same area, but this one is square. Louvered on the out side and meshed inside and out with the same 16 gauge stainless steel mesh.
It’s always a challenge to work on an extension ladder up at 5 metres these days, but no one else is going to do it. I was a bit concerned about installing it, and put it off for a few weeks, but due to the Lock-down, I can’t really get someone in to do it. Having left it for some time, waiting for the work fairy to turn up and do it for me. But yet another no-show. Maybe the work fairy is restricted by lock down too? So I finally got up the gumption and did it myself.
I had intended to install a large stainless steel hood over the electric kilns end of the kiln room, but due to lock down, I can’t get my hands on any stainless steel sheets, as there are no commercial stainless wholesalers within 5 kms of Balmoral Village.
Kilns fired on different fuels can’t share the same venting flue system, so LPG , Natural gas and wood, can’t co-habit, nor can you flue electric and fuel kilns together.
We have been gifted a small top loader electric kiln by Rohde. Thank you Rohde! The gift was organised by my friend Len Smith. Thank you Len!
As I can’t build a large flue canopy for the electric kiln at the moment. I have bodged up a temporary extraction fan in the window next to the kiln. It will do until I can build a proper one.
I made it so that it can be installed and removed easily and also used in the next window later on as a dust extractor when I’m making up glazes.
I made these two wooden blocks with rebates on both side, plus top and bottom, so that they can lock into the window frame and allow a sheet of plywood with the fan mounted in it to slide in and be held securely. While still being able to be removed easily. I even made them using wood that we grew, milled and dressed our selves.
We have done one test firing to dry the kiln out and establish the protective oxide layer on the elements. The kiln has a small tube fitting that allows the fumes from the kiln to be directed out of the room through ducting. (not supplied.) I have directed the vent fumes out the window through the fan. The vent is only 25mm dia. so I have used 90 mm dia. pipe to vent it out through the fan. This allows a massive excess of cold air from the room to mix with the vent fumes to cool them. allowing the use of plastic pipe. I’d prefer to use a gal steel pipe bend, but I don’t happen to have one. Maybe later.
To finish off everything in the kiln room, we have the LP gas Plumber coming this week to certify the gas line installation. If all that goes ahead, then All we have left to do is make up some test glazes and do a test firing full of glaze and body tests. Slow but positive progress.
I have now made 2 sizes of name stamps. Small ones for smaller domestic wares, and a larger pair for bigger pieces. I do these small jobs before and after work in the mornings or afternoons. We have bee throwing now for parts of the last 3 days. Not all day, as there are still so many other jobs that need our attention. Like planting peas, beans and Kohlrabi in the vegetable garden. Planting out 3 potted peach trees that were rescued from the fire and spent the last year and a half in large plastic pots. It’s almost spring and I need to get them in the ground before they burst their buds.
I also made a 550 mm high 3 legged stool, custom made to suit me for throwing on the new shimpo wheel. I fashioned it out of some fire wood set aside for firing the kiln.
We are slowly filling the bench tops with more pots.
Today, in the middle of the day, we were both heads down at our wheels opposite each other throwing in silence, listening to a CD. When the music stopped, neither of us got up to change the CD. We were immersed in our work. We worked on for some time in complete silence. These new wheels make no noise at all. Our meditations broken only by the sound of a lump of clay being occasionally slapped down onto the wheelhead. The 4 large windows were open and it was a warm, balmy day. I slowly became aware of the noise of bird song outside, the warbling of magpies and then the sounds of chickens walking past the window gently clucking to each other. In the distance I became aware of the faint sound of the Willie Wagtails chat, chat, chatting to each other as they do their aerial gymnastics chasing the invisible gnats and insects in the sky. There are also half a dozen swallows diving and swooping. They even swoop around inside the car port. Stopping to rest on the beams. Janine suggests that they are looking for nesting sites. 2 even flew in through the pottery window and then got stuck inside, not being able to find their way out again, always flying up to the clerestory skylights and banging into the poly carbonate with a repeated ‘thung’ sound. One eventually flew out through the open door. but the other had to spend the night inside. It flew out as soon as we opened up in the morning.
It’s uplifting to see a few birds establishing them selves in this garden again.
It was a moment of precious rural idyl. I realise just how incredibly lucky we are to live here like this. There may be lock down everywhere around us, but we are happy ensconced here in our own little creative world. There is food in the garden and eggs in the laying box. We want for nothing. (except maybe a pug mill)
I spent a bit of time making another smaller set of initial stamps, for when I start to make smaller domestic items like cups.
My next part time, after work, job will be to get the kilns firing. We have both a very small electic kiln and a gas kiln that I’m working on bit by bit. We are almost there. They just need some finer details sorted out. If all goes well we will have a load of dry pots ready for a bisque firing in the electric kiln and then followed by a glaze firing in the gas kiln.
Building a wood fired kiln will have to wait till summer, after the Open Studios Weekends – if they happen? which is starting to look unlikely at this stage.
But before that can happen, I need to make a massive number of glaze tests for that first firing. We have to test a lot of materials. some old bags of uncertain origin that have been storred for years in the part of the barn that didn’t burn, plus others that we have inherited and some that we bought from John Edye when he retired. It was my intension to go out and collect a load of stones from around the shire to make my glazes. But that can’t happen now until lock down is lifted, as there is only one stone within 5 kms of here, and its rather dull, being a basalt. A 5 km limit really restricts my glaze choices to wood ash and basalt. It’ll all happen in good time – sometime. I’m working on it. At least these sorts of jobs are ceramic related and a change from building work.
Nothing is ever finished, Nothing is perfect and nothing lasts for ever.
We are finally back at work.We have finally got off our lazy bottoms and are back at work on the wheel – albeit only after a long morning pause while we made cutting wires and I carved us each a name stamp.
I started by making a few chucks. These are clay tools used to support pots while they are being trimmed and need to be made first so that they dry out to be stiff enough to support the pots when they are trimmed. I have learnt to keep my chucks damp, wrapped up in plastic and dunked in water after each use, so that they last for several years, kept constantly in a firm but damp state. Janine started her day by making door knobs for the cupboards in the gallery room.
The batch of clay that we made a month ago is working OK. It’s a little soft, but easy on the wrists because of it. I started out using the hand-me-down wooden ‘Leach’ kick wheel, which has always been my favourite style of wheel. but this one is completely worn out. it creaks in all the joints – like me, and needs new bearings, as someone filled the entire tray with water till it over flowed down the inside and poured through the top bearing , filling it with clay dust. I’ve tried twice to get the wheel head off, so that i can replace the bearing, but it stubbornly refuses to budge. I have owned 6 of these wheels in my career, all 2nd hand, and have replace bearings in some of them. I have found that there have been 3 different methods of attaching the wheel head over time. They appeared to have changed the design to make manufacturing cheaper. The earlier models had the wheel head screwed on with a large format thread cut onto the shaft and wheel head, the second method involved a ’T’ section fitting with a pin through the head and shaft, and the last one was just a simple ‘Morse’ taper that relied on friction.
I’ve tried tapping up and twisting sideways, but this one is very stubborn. The frame was so loose and wobbly that i went down to the ‘spare parts’ pile and found some heavy gauge gal strapping and made a series of diagonal bracings for the creaky wooden frame. That stiffened it up, but it still growls.I gave up on it for the time being, as today was all about throwing some pots. I migrated over to the Shimpo wheel that was a gift from Len Smith. What a wonder this wheel is! completely silent and totally smooth. this is my new wheel of choice now.I need to make a proper stool that is the right height for me. So many jobs still to do!
I have become so used to using beautiful clay straight from the Venco vacuum pug mill, that i had forgotten how long it takes to prepare clay from scratch by spiral kneading. It takes ages to get all the air out! But at least the new timber wedging bench is just the right height.
This last week, we have been working on getting the gallery room finished. This is the last big dirty job to get out of the way. Once this is done we can really start to clean the place up and get ready to make some pots. There is of course loads of other jobs to complete before we can fire anything, but they can wait. They will get done in good time while our first pots are drying.Some of these other jobs will include getting the kilns ready for firing. However, in the meantime we have cut the huge pine slabs that we milled 20 months ago. I have sawn them into rectangular planks 3 metres long and 750 mm wide and 80mm thick. Not too many people can afford to use timber like this in their gallery. We can’t! It would be completely out of our reach if we had to buy it.
We can only do this because we grew the trees our selves. We got the dead pine trees that were killed by the fire, felled professionally, as they were right up against the house. We then hired a portable saw mill to cut them up into big slabs for bench tops and planks for lining boards. They have been seasoning for the past 18 months. I had to build an extension bar for my small hand pumped hydraulic crane on the truck. An extension of 3 metres is a bit far, but it worked quite well. I took the first lift very slowly to test that it wouldn’t bend under the load. A few weeks ago, I had a friend come and help me lift and shift these massive slabs onto the ute. But we are now in total COVID 19 lock down statewide, so another solution had to be devised. This way, I can do it all myself.
The huge slabs needed to be cut to have parallel sides and squared off ends, then planed, and sanded a few times with ever decreasing grit sizes of 40#, 60#, 80# and 100#, finally washed to raise the grain. After drying, the rough raised grain texture was again sanded with 80# and then 100# to get a fine finish. There are so many hours of work in getting a massive surface like these slabs from a very rugged chain saw finish, to glassy smooth. I’m not a wood worker, so I don’t have access to any large wood working machinery. All this had to be done with hand held tools. I have to thank my very good friend Len Smith for giving me all his Makita power tools. I need 4 big slabs for the bench tops and 24 planks of 2.4 metres to be dressed like this to make the shelving. It’s taken me over a week. Once the slabs were finished, I needed to shorten the crane arm to lift them onto the truck to drive them up to the pottery.
I needed to weld up a suitable steel frame to support all this wood.
We’ve ended up with something that resembles a massive kitchen dresser. One on each side of the room, with another huge slab table in the centre. This gives us plenty of storage space in the cupboards and a lot of flat display space. We spent today sweeping, vacuuming and generally cleaning up all the saw dust that ended up coating everything in the place. That is all now done. This was the last really messy job. We can now relax a bit and look forward to making some creative work.
Tomorrow I will start by making some throwing and turning tools. My first job on the wheel will be to make some clay ‘chucks’ to get them stiffened up so that I can turn my pots once I start to make them.
