Three Wood Kiln Firings in Two Weeks

We fired the big wood kiln last weekend, then during the week, Janine packed and fired the little portable wood fired kiln.

We have put the Sturt ’Terra Nova’ show up and it is going well, with a big turn up at the opening. We got to catch up with loads of people that we only usually see at conferences, and as I don’t go to a lot of conferences, nor do I go to ‘openings’ to do ‘networking’. Well, I don’t get to catch up like this very often. It was really good.

Our next big event on the horizon is the ‘Pop-Up’ Artists Open Studios Arts Trail, that will be on the long weekend of the 10th, 11th, and 12th of June. Hence the flurry of firing activity now in preparation. We have been making all year, and firing in the smaller kilns, the solar PV fired electric kilns. We don’t fire the wood kilns over the hotter part of the year, and certainly not during the fire-ban season. So it’s all go now.

Using a combination of elm garden prunings and some thinly split eucalypt (many thanks to our friends, Susan and Dev, who helped split a lot of side stoking wood with us a month or so ago.) Janine was able to fire up to Stoneware in reduction in 4 1/2 hours. A perfect firing for a little portable kiln.

At the end of the firing, Edna the chicken came to check it out. Janine and Edna had a little chat, cooing and clucking together. The gist of it was probably around the matter of if there was anything for a chicken to eat?

I have been packing the big wood kiln again for another firing this coming weekend. The slowest part of packing the big wood kiln is rolling out all the thousand little clay balls of wadding. Each pot has to sit on a ring of little balls of refractory wadding to stop it sticking to the kiln shelf. Over time, and many, many, firings the kiln shelves get a coating of molten fly ash from the burning wood, and if the pots aren’t held up off the shelf, they will fuse together at high temperature becoming a monolithic whole.

First chamber finished and clammed up.

I think that I probably spend a quarter of my time rolling out these little balls, only to throw them away after the firing. Actually, Janine re-uses them as aggregate in the bottom of planter pots around the garden. However, when we first set out on this creative journey, back in the early ’70’s, because we had very little money and couldn’t afford to buy the very expensive kiln shelves that we needed to pack the big wood kiln. As a work-around solution, we decided to make our own. This was a very tricky bit of ceramic chemistry, and only one other husband and wife couple of potters, Harry and May Davis in New Zealand were doing it. We went to work with them to get some insights, and came back and made our own kiln shelves for next to nothing in terms of cash outlay, but a lot of time invested.

The cost of the high alumina grog used to make refractories was prohibitive, so we made our own. For every firing in the little test kiln that we had, I used very high quality, high alumina kaolin from Mudgee. Puggoon 157 kaolin, purchased directly from the mine not too far away, to make the wadding balls. After firing, instead of throwing them out. I put them through the rock crusher and turned them into high alumina crushed grog. All the failed experimental kiln shelves were also put back through the crusher, mixed with more kaolin 50/50 and used again. Eventually we had enough kiln furniture to fire the big 300 cu. Ft. wood kiln at next to no cost. They weren’t very good, but just good enough and this exercise in self reliance got us going. We still have them, but they are rarely used these days, because the new silicon carbide kiln shelves from China are both affordable and excellent quality.

Preparing for the first wood firing of the year.

This week is the mid point of autumn, Half way between the equinox and the solstice.

The weather is certainly a lot cooler and we notice that the days are so much shorter. I really like this slightly cooler alternative the long days of summer. Our summer wasn’t so hot as it used to be during the decade of el-nino years. These last few summers have been so much nicer, cooler and wetter, everything has turned green and grown its head off. We have harvested more tomatoes then we have ever grown. It seems that all the planets aligned for the tomatoes. I haven’t counted the bottles, but there must be over 40 jars. Quite enough to last us well over 12 months, possibly even 2 years?

We went to Canberra over Easter for the National Folk Festival.

We caught up with people that we haven’t seen for over 4 years, as we were confined to home because of;

1.  The fire, 

2. The on-going clean-up,

3. The rebuilding,

4. Covid, followed by a year of lock down. 

It’s only now that we feel that we have the time, space and safety to go out again. Womad was on again this year, but we chose to stay home, save time and money and get on with some of the long list of jobs. However, we decided to go to Canberra for ‘The National’, as we can drive to Canberra in just 2 hours in our electric car. Travelling to Adelaide for Womad is looking more and more extravagant and carbon intensive, regardless of whether we drove or flew, we were responsible for burning loads of carbon each way. I just can’t justify it anymore.

The long weekend of music was wonderful, so many great acts, too many to list, but a few stood out.

The ‘We Mavericks’, Lindsay Martin and Virginia vigenser, were excellent. We have had them here in our home to perform for us in one of our house concerts a few years back. I believe that we were their second only performance together. They get better and better.

Billy Bragg was also really good. He was the best that I have ever seen him. Powerful voice, smack on key and few very powerful, short spoken interludes between songs, on why we should care about the state of things and the world. He also explained what he is doing to make a difference. Very inspiring. However, it crossed my mind that he must owe a tremendous carbon debt?

We also enjoyed Gleny Rae Virus, Leroy Johnson, (above) the Park Ranger from Mutawintji National Park out near Broken Hill, and Farhan Shah & SufiOz. singing Sufi devotional chants. + many more.

Back at home we have been Splitting wood for the kiln firing, and working in the garden. 

We met up with our friends Susan and Dev in Canberra, and they called in here on their way home to give us a hand with those jobs.

My friend Len Smith also called in and we had a little reunion. As Len, then Janine and finally myself, were Susans teachers at different times in her life, at different colleges.

Together, we ripped out 3 beds of waning tomatoes, that had reached the end of their productive life and added them to the compost heap.

Afterwards, I planted out lettuce and radish seeds as well as lettuce and spinach seedlings.

The garden suddenly looks a bit more loved again after a few weeks of minimal up-keep and absence.

My last job was to plant out 160 of our own self grown and stored garlic cloves. I should have been onto this a month ago, but better late than never.

I did two rows of 80, one of our purple garlic and the other of our white skinned variety. They have started to shoot from their skins. A very good sign that they are ready to be planted out now!

Everything takes time and time needs to be made or created by making decisions about what is most pressing and needs to be to be done NOW.

Tomorrow it is back into the pottery to unpack and repack the electric kiln for yet another bisque. Learning to Juggle my time and energy has been a life long exercise in developing this skill for me.

I want to do so much each day, Even summer days aren’t long enough. I need to triage my desires to fit my capacity to actually achieve outcomes. Added to this, I really don’t know what I’m doing most of the time.  I’m reasonably well trained in making pottery, and I have taught myself to grow vegetables and orchard fruit trees, but I have such a low basic understanding of building techniques and mechanical engineering, I just muddle through as best that I can. I rely on asking more knowledgeable friends for advice on what they would do, or where is the best place to buy the correct parts.

I’m so grateful to all of my friends for the advice and help that they have given so generously over the years.

When we built the new ‘kit-form’ tin shed for the new pottery. I paid a bunch of so called ‘expert’ tin shed builders to come onsite and erect the kit. They had experience and all the fancy gear to do the job. A bobcat loader, a scissor lift gantry and a truck load of power tools. They put the frame up OK. It is at least level and vertical. But when I asked them to screw on all the 2nd hand, grey re-cycled old rusty gal iron sheeting that I had collected to give the shed some character, they did the worst job that you could imagine. They chose to use roofing screws without any rubber ring to seal out the weather, and as a consequence, all the walls leaked in heavy weather. The windows weren’t ‘flashed-in’ correctly or at all, and leaked. The cement slab was cast with a definite hollow in the centre. The verandah wasn’t ’stepped-down’ 50 mm to stop water blowing in under the doors, so that when it rained hard, the building leaked, all the water ran to the centre of the building and pooled there. I’ve spent over a year discovering all these faults, omissions and bad workmanship and then correcting them as best that I can. If only I’d known something more about the building trades, I might have spotted these faults occurring and got them seen to at the time. But I trusted them. BIG mistake.

Our previous three potteries that burnt down were all home made on a shoe string budget mostly out of wood and other materials that we could scrounge off the side of the road on council clean-up day, or from the tip. They too had character, but a very different character. This last shed is so much better in all sorts of ways, but mostly it will be easier to defend against fire. Metal clad, metal frame with metal lining and the cavity stuffed full of insulation. All the previous buildings were made of wood and therefore were very flammable.

It seems that I have discovered all the problems with the poor workmanship in this shed now. I’ve discovered all these faults bit by bit over time and fixed them myself. The builders have shot through. There is something to be said for self-reliance.

Do it yourself, do it right the first time. I do it to the best of my ability. If it isn’t the most professional job, at least it is mine and any mistakes are honest ones. The stuff that I do has my character printed all over it. I own my mistakes, my lack of skill and my incompetence, but in the end I figure it all out and I can live with the result. At least I’m not upset with myself for ripping myself off. AND everything is done on a minuscule budget. We have never earned much money, so have learnt to live very frugally.Everyone seems to be obsessed with money these days, as if it solves everything. I heard on the news that the 3 richest Australians have more money than the bottom 10% of the nation. Pretty shocking! It’s a shame that there isn’t a way of making life a little bit more even and equitable for the disadvantaged. The Lovely and I have done very well for ourselves, being able to have built a simple, largely non-acquisitive, low carbon, organic lifestyle here, without ever having had a ‘real’ job. We’ve managed to ‘get away with it’ for all this time, living an engaged, creative, self-employed, part-time amalgam of a life. Without credit card debt or interest payments, doing almost everything ourselves. Living within our self-determined means. We’ve never been on the dole and never asked for handouts. Money may be essential in the modern world, but we don’t let it ruin our lives.

As an example of this frugal self-reliance I recently fixed up an old Chinese wood splitter. It needed a new/old/2nd hand starter and air cleaner to get the engine going again. That wasn’t too difficult. I just stole the parts off another old ruined motor that was in the barn. Best not to throw things out if they might have useful parts on them to keep another machine going for a few more years, There is a lot of embodied energy stored in those old bits of machinery. So it’s better to try to repair something old and get extra life out of it, than to give in and buy a new one. It’s also much, much, cheaper

Once I got the engine working, I decided to make it into a bigger splitter with a longer stroke. All cheap Chinese hydraulic splitters have a 600 mm. (2 ft.) hydraulic ram. That is the upper limit of their log capacity. My new kiln has a fire box length of 690/700 mm. (2’ ft, 4” inches). To give the splitter a longer stroke I decided to cut 75 mm. (3” ) off the cutting wedge to make it shorter ,and therefore add extra length to the logs that can be split.

I wasn’t sure that it would work, but it seemed a lot easier than cutting the end off the frame and welding a new section of RSJ onto the frame to make it a longer machine. 

By shortening the blade I achieved the same outcome with much less work. But an hour on the angle grinder was a bit of a chore, as 20mm thick steel plate doesn’t cut easily.

You can see in this image that the blade used to go all the way to the bottom of the backing plate. 

Scrooge’s technique of making a bigger splitter out of an old small one.

The old small engine managed the longer wood OK. I filled the truck with wood cut and split to 675mm long.  That is about enough to fire the kiln to stoneware in 14 hours.

2 1/2 stacks of Hob wood,  

A couple of piles of smaller kindling lumps for firing on the floor,

and then a couple of stacks of thinner side stoking wood for the 2nd chamber. Thanks to Dev and Susan.

I finish the day by servicing the chain saw. Best to do it when it’s fresh on my mind, even though I’m tired from all the work, fixing the splitter, then testing it out and finally stacking all the wood.

I hate it when I go to use the saw and find that it is blunt and needs servicing, So I do it straight away. Sharpen the chain, blow out the air filter, rotate the bar, fill with 2stroke and bar oil.

It doesn’t take so long and everything is ready to go again, — except me!  I need a rest.

4 wood kiln firings in 4 weeks

We have been hard at it in the pottery preparing for the Arts Trail – Open Studios and the TACA Open Studios weekends coming up very soon. It starts next weekend.
We have just managed to squeeze in one last wood kiln firing. But this will be the last for some time. Mainly because I’ve just about run out of dry glazed pots, but also, because from now on the weather will be getting too hot for safe wood firing over the summer.

This firing seemed to go very well, just 11 1/2 hours to cone 10 down, not quite so hot on the top back shelf with cone 8 over, but cone 10 just starting to bend. Probably cone 9, close enough.
I changed to pack again this firing just see if I can get a better understanding of how this kiln responds to subtle changes of setting. Life is endless learning.

I got a very good control of the ember level with this firing. I’m pleased about that. We have been getting rather too much ember build-up towards the end of the firing in the last few firings, so I opted to open all the mouse holes right from the start. I can’t remember ever doing this before, but it was just right and worked well, kept everything under control. I’m a slow learner, but I get there in the end.
I recon that this wood firing lark is quite good fun. I’ll probably have another go at it 🙂
We’ll see how it has turned out in a couple of days.

We have also lifted the 2nd planting of garlic. This bed of garlic was planted at the same time as the previous batch that had split into individual cloves. This variety has taken a few weeks longer to mature and has stayed as complete bulbs. This bed of garlic has delivered around 50 knobs. The last bed lifted out 45 split knobs. We still have one more double sized bed to go, maybe in a few more weeks? It may have up to 100 plants, but we’ll have to see what matures and lifts and dries successfully. Not all our garlic plants mature to a full supermarket size. We get quite a few small knobs that are a bit tedious to peel, but the flavour is still all there.
We can get through up to 300 knobs of various sizes of garlic in a full year, and that isn’t always quite enough to see us through till next years harvest. This year we ran out of our own home grown organic garlic about a month ago and had to buy 4 or 5 knobs to get us through to a time when we could start to ‘snaffle’ or ‘steal’ a few very early plants from the edges of the first bed.
I love fresh, wet, early, fragrant garlic. I have to have a couple of cloves sliced on my homemade rye bread, with a twist of fresh ground black pepper and a tiny sprinkle of salt. Tonight it’s just not my fingers that smell of garlic. Keep your distance!

The first lifted crop is now all dried, plaited and hung in the kitchen ready for use.

3rd wood kiln firing in 3 weeks

This weekend we fired the wood kiln again. The third firing in 3 weeks. One firing each Weekend. This firing went very well.

I’m starting to get the measure of this new kiln and my endless supply of pre-burnt wood fuel. For the first of these 3 firings, I altered the firebox and made it deeper, which helped. Before the 2nd firing, I changed the flues. For this firing I changed the setting and adjusted the flues slightly. more fine tuning than major change. All these adjustments have come together now and this last firing was even from top to bottom, with cone 10 over on each shelf, as well as the floor.

There is still an issue with the wood. The flame is quite short and although cone 10 was over on the front of the top shelf, we only got cone 9 over at the rear of that same shelf, just 400mm further back.

Still, everything is well melted and looks good. We have plenty of pots fired and ready for the two open Studio Weekends coming up.

It was a very foggy and misty dawn for the firing.

All of our specially developed home made wood firing clay bodies have taken the fire well and are flashing up with good toasty colour.

This is one of Janine’s bowls with her home made cobalt infused pigment brushwork and her ash glaze made from the ash out of our kitchen slow combustion cooker. This bowl has picked up a little bit of carbon inclusion around the rim. Janine doing her bit to remove carbon from the atmosphere permanently and counter global warming.

This is one of my bowls that I decorated by trailing Janine’s opalescent ‘jun’ style ash glaze over tenmoku.We have just harvested the first of our 3 garlic crops. This year I planted two different types of garlic, one breaks up just before it’s ripe and ready to harvest, sending up multiple new green shoots. The other variety continues to grow as normal. I planted these two varieties last year as well and they did the same for me then. Very odd. The cloves are perfect, just separated into individual cloves.

The multiple stem variety is on the left.

We lay it out to dry for a week, then Janine plaits it into bundles and we hang it to dry until we need to use it.

Our Recent Woodfired Kiln Results

Our firing went as well as could be expected. I’m learning more all the time. The back of the kiln was under-fired, but 80% came out OK.

I ‘borrowed’ some of my friend and neighbour Sandy Lockwood’s wood. Sandy fires with wood too and lives only a few kilometres away in the same village.

Sandy buys all her fire wood in, so her stock of wood is totally different from ours. Our on-site burnt forest that has been left standing, but dead, after the catastrophic bush fires of 2019 doesn’t burn the way it used to.

We have been nurturing our few acres of eucalypt forest for the past 46 years that we have lived and worked here.  Carefully and very selectively dragging out the dead branches and tree trunks from the bush for use in our kilns and home. Almost everything that we do runs on wood for fuel. We obviously fire the kiln with it, but we also have a slow combustion kitchen stove that cooks our meals, warms the kitchen and also heats the hot water for the house. Then there is the slow combustion heater in the lounge room that we use during the cooler months to keep us warm at night. We also have a slow combustion stove and room heater in the pottery shed.

I get a lot of sowing done repairing my worn-out clothes, sitting front of the lounge room heater during the winter. I wear the clothes out chainsawing, cutting, carting, splitting and stacking all the firewood. It’s a bit of a circular economy. 

We have so much of this dead wood now, I have to find a way to use it creatively. I have another couple of firings scheduled in before the Australian Ceramics Assn, Open studio weekends of the 12th Nov. This overlaps with the Southern Highlands Arts Trail, Open Studio weekends on the first two weekends in Nov. We’ll be open for visitors on all 4 days of those weekends.

I will use these next firings to try out different approaches to solving my dilemma with this wood. If I can’t find a way of burning it successfully in its current form. I will have to change the fire box arrangement. But I’ll try all the easier options first. Side stoking the back chamber will probably work well, but I don’t want to do too much of that until I build an afterburner and flame tube with a spark arrestor on top. I don’t have time to build that until after the open studios in a few weeks.

So the next couple of firings will concentrate on fuel management, then packing and firing technique.

Here are a few of the roasty toasty pots that I left unglazed on the outside to pick up colour, fire flashing and a little wood ash from the one day firing. I used to fire the wood kiln for between 12 to 14 hours, but now with the change in the timber, I need to fire for 17 to 19 hours. Too long for an old guy and his hard working Missus. I was completely trashed the next day.

The colour is lovely and warm and the surfaces are very tactile.

Working with this rough, iron stained stoneware clay has been such a pleasure after the past few months of battling with the ground-up-sericite-stone bodies.

Recent wood kiln firing

In preparation for the up-coming Open Studio Weekends on the first two weekends in November, we have been hard at work making and firing to get everything ready in time.

We are still working on the pottery shed, as it isn’t quite finished yet. So much to do, but it is almost there. We have to stop the building work to concentrate on making pots now.

There are so many little bit and pieces of the building that need to be cleaned up and properly finished. The team of shed builders who erected the frame for us were working very quick and rough and left a lot to be desired in terms of details. I’m still finding out the places where they didn’t finish off the flashing, or didn’t put enough silicon in the joints here and there. But their biggest crime was not using metal screws with rubber seals, so I had to go around the whole building and squeeze silicon rubber over all the external screws to waterproof them. It probably only saved them $10. Such is the state of modern building trades. Fortunately we didn’t buy a high rise home unit with cracks in it, so we couldn’t live in it, but still had to pay the mortgage. That is so unforgivable. With all this rain over the past year, I’m still discovering places that leak or just little annoying drips that need attention. 

The framing crew did at least get the frame level, square and true. I’ll give them that much. The building inspector from the council who came and inspected our job, told us that this was one of the better frames that he had seen. Some were so bad, he had to call the builders back to straighten it up.

Janine and I have done nearly all of our building work over the years as owner builders here for the past 45 years, but this rebuilding job was just beyond us in our ’senior’ years. Especially the scale of it and particularly after working ourselves into the ground with all the clean-up work that we did after the fire. By the time it came to start re-building, we just didn’t have the energy. After the 6 months of cleaning up, we were ready to hand over to a team who supposedly knew what they were doing when it came to erecting a steel fame shed — sort of. They were certainly well practised at making short cuts.

This last weekend we fired the wood kiln. This was our 2nd firing in this new kiln and we are still learning how it works and getting to know its peculiarities and character.

We had Len Smith, Rob Linegan to help and Jan Kesby called in after her workshop at Sturt Pottery to give us a hand, as she was in the neighbourhood.

Lighting the kindling fire with just bark and twigs.

We will unpack later in the week after it has cooled down.

Janine putting stones into the rock crusher. Wearing her dust mask and with the exhaust fan pulling any dusty air from the room.

Janine has been crushing and grinding her beach pumice stones to make her sea-ladon green glaze. Made from just beach pumice and beach cuttle fish carapace ‘shells’.

She has also been making up her ‘Chun’ or ‘Jun’ blue opalescent glaze  that she makes from the ash from the kitchen slow combustion stove.

They both require crushing and then grinding in the ball mills to get the best result. There are so many little steps that go into being a self-reliant artist that most people just couldn’t imagine.

Then there is the splitting and stacking all the wood for firing. Everything takes time. We only have pre-burnt logs to fire with now, as every tree on our block of land was burnt. So we have a few hundred tonnes of standing dead wood to use up for the rest of our lives, but regrettably, since it is already pre-burnt. It has lost a lot of its volatiles, saps, kinos and resins. This means that we have to invent new ways of using it up in the kilns, as it is a bit like firing with charcoal than fresh timber. It still burns, but with a short flame and doesn’t really crackle and roar like it used to pre-fire. One solution I’m trying is to split it finer, where that is possible, but the stringy back that grows around here has a very twisty, gnarly, well integrated grain, that doesn’t easily lend itself to fine free-splitting.

Another option is to re-build the fire box to adapt it better to this charcoal rich environment, larger and with more provision for burning charcoal and ember? That’s a much bigger job, so I’ll try all of the easier options first. Time will tell.

Two Girls in a Man Shed

Last weekend we fired the new wood kiln for the first time. Not the best firing that I have ever had, but OK for a first firing. There is always a bit of a learning curve getting to know how a new kiln works. Becoming familiar with its particular traits and ‘personality’. We are also using pre-burnt wood from the bush fire. Burning in the kiln, what was recovered from the trees in our front garden. It’s strange and burns quite differently from the trees that we are used to burning from our forest that were unburnt.

This image taken by Warren Hogden

We fired for 14 hours through the day, and into the night. A very comfortable time frame and just about standard for the sort of firings that I have developed over the decades in this style of kiln.

There were a few losses. Two of my large 450mm dia. porcelian platters dunted on cooling. There is always a possibility of this with very large flat ware, and especially so with glassy, dense porcelain bodies.

Despite these couple of losses. I managed to get a few more nice pots out for the show at Sturt Gallery next weekend.

Inside and out shots of this deep dish. I have been using 5 tones of home made cobalt pigments and washes

I used the iron rich soil from the side of the road off the top of Mt Gibralter near here in one mix. This moderates to inky blueness of the cobalt.

I also made another batch of smalt-like pigment with local iron rich ochre with metalic flakes of iron oxide that I scraped off some of my burnt machinery that I was recovering for re-use. The mild steel parts that got burnt in the fire and then left in the rain for a year before I could find the time to get back to them, had rusted badly.

I flaked off the worst of the rust and collected it in a container for use as pigment. It’s a nice idea to re-use some of my old ruined equipment and incorporate it into my new work creatively. I think that this flakey iron oxide is probably mostly FeO and some Fe3O4, with very little Fe2O3.

Since the firing, I have been out splitting more wood for the next wood firing, helped by the chickens of course. They even followed me into the workshop where I had 2 girls in a man shed!

Open Studio Weekends

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.

Kilns

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.
