We are up bright and early and out into the street. We are foraging for breakfast. There are any number of street food vendors plus a few cafe style shop fronts open for our custom. We’ve had a gut-full of intestines for now. We are thinking of steamed buns, but this morning there doesn’t seem to be too many about. We take a walk through the local market, that is down a lane and along a walk way which opens up into a covered market in behind the main street. You wouldn’t know that it is there except for the stream of people and motor scooters that are coming and going along the narrow path simultaneously. It looks like total chaos in there, but is just the normal too-ing and fro-ing of humanity. We realise that we just have to push in and shove our way through, just like everyone else. No-one seems to have the Western concept, that we were brought up with, of taking your turn. it just doesn’t happen like that here. People aren’t being rude. it’s just the way that everyone gets about when there is a crush, and there always seems to be a bit of a crush.

Carving Out a Living
While our pots are drying, we go on an expedition to visit a few of the local potteries in the area. This whole city is dedicated to the making of porcelain. there are thousands, if not 10’s of thousands of small workshops all over the city. We go to one of the nearby potters districts. We have come in this direction because there is a potter here that we want to meet. I am travelling with a PhD student from The ANU in Canberra and his interest is in tenmoku. The potter we have come to visit is the local Master of the Northern ‘Leaf’ Tenmoku Style, which they call ‘temu’ around here.
Note to self: Don’t buy plastic crap
Now that the weather is closing in, it’s a lot cooler and the days are shorter, and for some unknown reason, it keeps on raining. We have gone from bush fire protection and hazard reduction, to digging drainage ditches. Fortunately we have missed the flooding that is happening just now up the north coast and in Queensland. I suppose that it helps that we live on top of a high ridge of hills. We are very well-drained here.

Play is the Best Part of Work
Our New Small Wood Fired Kiln
There is an amazing potter in Switzerland called Stefan Jakob, who specialises in raku firing. <http://www.raku.ch>
He has been to Australia a few times. He is the inventor of the IKEA garbage tin raku kiln. It is a really impressive little kiln that is cheap, compact and very efficient of wood fuel. It fires raku really well and is such great fun. It is such a great idea that I wish that I had thought of it:)
We organise wood firing weekend workshops here through the winter months and some of them are for wood fired raku. However, Janine uses these little wood fired kilns to do her earthenware glaze firings.
Stefan worked with us here on a few occasions on his visits and he gave us one of his kilns each time he stayed. Having seen them work, it got me thinking that there might be another way of thinking about small efficient, portable, wood fired kilns. The only drawback to his fantastic idea is that the internal size of the garbage can is quite small and limited. So I decided to build a slightly larger size version of his concept. I made one lined in ceramic fibre like his original, but square and about 5 times larger in volume, so that we could fire larger and taller pots for the potters who come here for our raku weekend workshops. Now I have just finished a couple of slightly larger square ones lined in light weight refractory insulating bricks. The great advantage of custom building the stainless steel box is that it can be whatever size and shape you think you might want.
Because this RI brick version is a little too heavy to lift and carry around like the garbage can kilns, I made this one in a custom-built stainless steel box on a galvanised RHS steel tube frame and lockable castor wheels. It has all the same advantages of the smaller fibre lined garbage tin kilns in that it is great fun, portable, very quick to fire, very efficient of the wood fuel and being top loading it is very safe, quick and easy to load and unload for raku.
I’m always busy. The kiln factory is full with a large gas-fired, front loading kiln, a relocatable top loading gas kiln with an extension ring and two of the new small wood fired raku kilns.
We had our first firing in it the other day, just to test it out and it worked really well. Just 45 minutes up to 1100oC from cold, and then a 15 to 20 minute turn around for the raku. We used such a small amount of fuel, fallen branches/brush wood from the garden. Our big gum trees are alway dropping dead branches around the yard, so it was just 5 minutes work to collect enough for the firing.
This kiln sailed up to temperature so easily that I think it will be no trouble to take it up to 1200oC mid-fire and even stoneware in the future – when I get a bit more time.
This is about half of the amount of fuel that was used to get to 1100oC
I don’t propose that it will give any wood fired effects in such a short firing time, but it will melt glazes perfectly well. I did some research on one of my locally collected milled stone glazes a while back and I tried firing my little test kiln to stoneware in just 30 minutes with a 10 minute soak. I was able to do 6 firings to stoneware in one day and learnt a lot. If I kept a close eye on the temperature and used test rings to gauge the melting, I was able to get some lovely, soft looking, satiny matt glazes. So it is possible.
With so little at stake in a small kiln and the firing being so quick and easy, there is nothing to loose and everything to gain. But more than that, it’s important to me to be able to make my ideas come to life and experiment with different concepts in my own way and in my own time. Play is the best part of work.
Home Made Chainsaw Saw Mill
Over the past few weeks I have had over 500 hits on my article on self reliance including a little bit about milling my own timber. So I thought that seeing there is so much interest in building a home made saw mill attachment for a chain saw, I ought to put up a post with some more detailed explanation, including a few dimensions and some images to help explain what I did.
It’s pretty basic unit made out of scrap steel sections that I just happened to have laying about on the day, but it works really well for what I need it to do and that is to turn logs that are too good to burn, into usable milled planks. I haven’t studied this kind of gadget at all. This is my first attempt at building one. It seems to work OK, so i haven’t got around to making another one or changing it. If I was to, I would perhaps add a bit of rubber tube over the upright centre handle, just for comfort.
Since I moved here, I have built my own house and pottery building. We made all our own floor boards and made all the windows and french doors. I also made all of the kitchen furniture to go into it, chairs, tables stools etc.
All you seem to need is a few basic tools, an inquisitive mind, some perseverance and a bit of spare time to figure things out. The saw is an old (15 years) Husqvarna 371 60 cc. and the milling bar is about 900 mm. long. The effective cut is about 600 mm.
So here are a few pictures with measurements chalked onto the bench.
A Sudden Outbreak of Normality
We are just back from Canberra, it’s late afternoon and it’s straight into the garden to see what there is to pick. We’ve been away for 5 days. It has been raining a lot of the time we have been away. The rain gauge has 32 mm in it and there are puddles on the road coming in. It’s the end of the warm weather now and I manage to pick a full basket full of small red and yellow tomatoes. This will be the last picking large enough to fill a boiler and make tomato passata. From now on we will only be able to get a few each day, enough for one meal at a time.
I clean out the firebox and check all the new brickwork and bracing for cracks and then clean all the props and shelves, ready for the re-packing for the workshop.
The Axeman Cometh, but Lucie Takes the Cake
The April Fools New Firing
I’m awake before dawn. There isn’t even a hint of light through the place where I know the window is. It’s drizzling or raining lightly, because I can hear the drip of the rain on our bedrooms’ tin roof. I reach for my phone in the dark, it’s just 6 minutes before the alarm is due to go off. How do we do this? What sort of clock do we have in our heads that can measure by dead reckoning to within 6 minutes over 8 hours. If I tell myself to wake up at a certain early hour, I usually do it. I just don’t know how. I trained my self when I was a teenager, to wake up every two hours through the night, when I was firing my first gas fired kilns, so that I could turn the gas up, to get a steady temperature rise. That knack has stayed with me it seems.
I walk down to the pottery shed in the pitch dark. No stars tonight. Total cloud cover with some light drizzle. No need for a torch. I’ve walked this path so many times in my life. I know the way by heart. I turn at the corner of the orchard fence. I can’t see it, but I know that it’s there. I know that I’m in the shed now and reach for the light switch and suddenly, It’s all real instead of imagined.
The kiln is packed and was preheated last night. The wood is all split and stacked neatly along the far wall. Everything is ready. I light the match and the kindling crackles into life. I love the smell of the fresh cut and split wood, the smell of the smoke as the fire is slow to catch. I’ve learnt to light a small fire in the base of the chimney to get the chimney hotter quickly to establish the draught. It’s been a few months since I last fired this kiln and the chimney is cold and damp. It has sat idle over the hottest months of the summer, waiting for this day. The first day of Autumn and the official end to the fire bans. We waste no time in getting going. This is the start of the kiln firing season.
I have spent the last few days cutting, splitting and stacking the wood for these firings. Then carting and re-stacking the logs in the kiln shed. We have had a very wet summer, so we could probably have done a few firings on the wettest days, but I was fully busy making and installing kilns for other potters over the summer. I had plenty of orders, so I sold my soul for the mighty dollar. Paid work has been a bit thin on the ground these last few years, because of the closure of the art schools.
Because of all this wet weather, the wood is still pretty wet inside. It hasn’t dried out much over the summer. So now I have a shed full of wood that won’t get any wetter and will start to dry out a lot faster now that it is under cover. I really need an open walled wood shed over near the wood pile site, where I can safely store the split wood to allow it to season without risk of fire danger to the house or pottery. I was given about 60 or 70 tonnes of logs last year, 8 or 9 tip-truck loads. Enough wood for quite a few years. It all came from a building site in a near-by village.
Splitting wood can become quite boring over several hours. I manage to roll a few logs onto my shins during the day. I’m already wearing hard boots, ear muffs, face shield and gloves. It seems that I’ll now have to go out and get some shin-pads as well.
During the dull moments, I worked out that I had cut and split over 500 pieces of wood by the end of the day, then picked them up and stacked them onto the trailer, then unloaded them and re-stacked them in the kiln shed. That’s 1500 wood movements. No wonder that I’m feeling old.
We have spent a few days in the pottery throwing some of the fresh new porcelain stone bodies that I made over the summer months. It’s throwing quite well for something that is principally ground rock paste, with an addition of around 15% of plastic clay. It really has made a big difference to the workability. Now it throws more like fresh ricotta rather than wet putty.
We have a few tests of these new bodies in this firing. We also have the back of the kiln filled with our latest batch of home-made firebricks. These are all larger size blocks 230mm x 150mm x 150mm.
I will use them as door blocks. As the door of this current kiln is quite wide. Using larger blocks will make for faster door bricking-up. I am already using quite a few of these large blocks in the door, but not enough to fill the entire door. After this firing I will have enough and a few spares.
As the firing progresses into high temperatures, There isn’t a lot to do. While I wait between stokes. I sit and shell dried radish seeds. liberating them from their sticky pods. It takes an inordinately long time to do. It is so very fiddly and tedious. I’m a fool. I don’t know why I don’t just go to the shop and buy a packet of seeds. Well, actually I do know. I want to be a self reliant fool. These are seeds that I have grown and dried myself. They are mine and true to type. They are not hybridised or treated with poisonous anti-fungal treatments. Home-grown, organic and clean. The stuff of real life.
It’s a great big new experiment. A new firebox, new wood, new fire brick load, new porcelain bodies and new-season radish seeds.

A Skutch in Time Saves Nine
Now that my show at Watters Gallery is up and the opening is over, it is time to get stuck into rebuilding my kiln for the coming year of firings, starting next week.
<http://www.wattersgallery.com/artists/HARRISON/Harrison.html>
We are into the cooler weather now (in theory) and the summer fire bans will soon be over. The fire box is the part of the kiln that takes the most wear and tear, the greatest heat, the most ash deposit and the greatest heat shock from cold air dunting. The fire bricks in the fire box take quite a beating, so there is always maintenance after every firing, but then a big job once a year to replace dunted, chipped, broken and slagged-up firebricks. As well as chipping out lumps of built-up slag and ash glaze deposits, that if left unattended, will eventually flow like lava into important air inlet holes and seal them over, causing trouble during later firings. I get stuck into it with the skutch hammer and cold chisel.
Some years ago I didn’t get around to doing sufficient firebox maintenance, skipping a maintenance session, as we were very busy at the time. Unpacking the kiln and re-packing it ready for the next firing. But then, during that firing, towards the end, at the highest temperature, a lava-like flow of ash glaze came pouring out of one of the floor-level air-inlet holes. It pooled onto the floor into a sluggish, thick, brown, viscous, turd and piled up there, before freezing at room temperature. I kept that ceramic turd on the pottery window sill in front of my wheel for a few years. It disappeared when our pottery burnt down in 1983. It hasn’t ever happened again.
A while ago, I collected all the chipped out fire box floor ash glaze slag and crushed it up and ground it in my ball mill, into a fine powder, then made a glaze test out of it. It would have been a lovely completion of ‘joining the circle’, kind of thinking. But tragically it was so very dark and dull and brown and slightly crystalline, that I couldn’t find a use for it on my work. So, going on the theory that a skutch in time saves nine. We get stuck into the job at hand. Which is cleaning and rebuilding the worn bricks in the firebox. It’s not a very nice job, but has to be done, and needs to be done NOW!
However, Like all jobs, it expands and as we work. We realise that it would be far better and more economic of our time and efforts, to do a lot more rather than less, while we are at it. So we take down a lot of the fire box brickwork and re-design the ratio of hobs to ash-pit, to test out an old idea that I haven’t tried before. It is interesting to me that after building and firing well over a hundred of these kilns, for individuals, Potters Groups, TAFE’s and Unis, both here and overseas, there are still some variations and combinations of factors that I still haven’t tried. This idea needs to be tested. So off we go. It’s a new adventure now, and becomes more interesting because of it. It takes us two days to pull it down and brick it all back up again, then re-weld all the metal bracing, so that it is well supported during the stresses of the high temperature stoneware firing.
Ms Versatile is a very competent brick layer afters all these years of practice. We have built so many kilns together. Both here and overseas. I don’t know how many bricks we have laid together, but it must be in the many, tens of thousands. 900 to 1500 bricks per kiln, and over a hundred wood fired kilns built on-site in 40 odd years. When we first came here in the seventies. We were building our kiln when the local bull dozer driver called in to see about digging our dam for us. He walked into the pottery and saw Janine laying bricks on our kiln by herself. He stopped dead in his tracks and did a double take. Then said. “F%&k me! Now I’ve seen everything, a chick laying bricks”!
It was an usual sight in those days to see female bricklayers and he was a bit of an unreconstructed chauvinist.
We’re still at it. Nothing’s changed!
The renewed, slightly lower firebox. All finished and ready to go for another year..
fond regards from Dr. Skutch and Ms Versatile
