The transhumance is usually applied to the seasonal movement of livestock in Europe following good the pasture from lowland to highland in the spring for example. Janine and I have been in Europe on two occasions and witnessed a small part of this seasonal, ancient, ritual passage of people and animals. It was a beautiful experience, to witness this event, watching the farmer, his family and their dogs walking the herd of cows down the mountain pass, back to the safety of the lowland farm and its barn with its stocks of hay and silage to sustain the animals through the cold winter.
For Janine and I here on our few acres, we ‘husband’ the passage of water back up hill from the lower dams, up to the higher ‘house’ dam for safe storage over the coming hot dry summer. Back when the weather was more reliable, the winter rains would flow into the upper dam and it would overflow down into the next dam, and then from there, when the 2nd dam filled, it would over flow down into the next dam, etc. etc. We have created what is known as a ‘keyline’ system of dames, so that nothing is wasted. That was of course when it used to rain.
These days it doesn’t rain enough to fill all the dams, but they do have a small amount in each of the 2 lower dams. The big top dam, ‘Max Like’, is totally dry. but it is worth harvesting the water from the two lower dams and collecting it all in one place to minimise evaporation. The surface area is essentially the same, but the water storage is 3 times deeper.
So today I started the water-transhumance for this year. The water is supposed to flow down in the winter and be pumped back in the summer. I don’t have much to work with, but in this way I can get the best out of what I have.
I pumped the bottom dam down to a level that gave me most of the water, but left a little bit for the locals.
My next job is to move the pump up to the 2nd dam and start shifting it up to the top dam. By the end of the day we should have moved most of the water. There is a big rock in the top dam, when we can see the rock, it means that we are almost out of water. By the time I’ve pumped all this water up to the top dam, the rock will disappear.
Mission accomplished. The home dam is filled sufficiently to cover the rock. That means that we now have over 600mm. deep storage, all in one spot, which minimises the evaporation in there coming hotter weather.
While the water was pumping up by itself. I only need to check it every 15 mins to make sure that all is going well. In the mean time I finish filling in the syphon guttering trench and I make new guttering for the western side of the barn. I was quoted $110 per meter for a professional guttering job. I manage to do it in 3 hours for $147! I just saved myself over $1,000! This is how we can manage to live here on such a small income. Independence through frugal self reliance.
I have spent this long week doing repair and maintenance jobs, from replacing the tin roof on the pottery, renewing the syphon gutter and digging trenches through hard packed dirt, making gutters and down spouts, now shifting water.
Every step I’ve taken this week was involved in water in some way. You never miss your water till your well runs dry!
I’m hoping that I won’t miss any water and that my tanks won’t run dry.
As the weather has slowly dried out over the four and a bit decades that we have lived here, the dams that we dug when we arrived here in 1976, and worked so well for 20 years, are now all dried out. We haven’t had significant rain fall to saturate the ground and flow down the gutters and channels into those dams. So we find ourselves towards the end of spring now with virtually no water in the dams. This is the 3rd year with no significant flows into the dams and the 2nd decade where the dams don’t fill to overflowing. i can’t remember a time when they were all full.
It is quite shocking to me to have to start the year with just 500mm. of water in our main dam. That will only last a couple of hours in a fire situation – if it came today! But there won’t be this much water left in there in a month or twos time, at the height of summer – if any! Evaporation will see an end to that little bit of water that is left.
Our biggest dam, built specially to irrigate the vineyard, we called Max Lake! It is now bone dry since last week, the final little puddles evaporated away in the heat and the wind. No water flowed into it for at least 3 years. It was once a glorious swimming hole in years past. Particularly when our son was young, we had a lot of fun swimming in there over summer. 2 metres deep of serious fun filled water. Now home to just a few dried out reeds.
We used to rely on the dams for our irrigation water and fire fighting reserves. But no more. We have to think differently now. This is now the new normal. We have managed to get through the past few summers using our tank water storage. We have put a lot of effort into installing water tanks on every roof on our land. This has worked very well up until now, But this year we are not quite through spring and we have almost emptied one of our two large water tanks, mostly through watering the garden and orchards. With the global crisis deepening, I can see a time when we will run out of water before the end of summer in coming years.
The most pressing question on my mind right now is what will we use to fight bush fires in late summer and autumn. I guess that we will have to buy water and have it trucked in. Not a happy thought. In particular because when disaster strikes, every one will be wanting water delivered and only the regular customers will be getting service. I know how it works. We have never bought water for 40 years. We don’t even know who sells it these days. So we shouldn’t be relying on that to save us. In a funny quirk of fate, those of us in this village who are poorly prepared and always buy water, will get it, as they must, because they are the most needy. We, on the other hand, have spent our lives trying to be prepared as best that we can be, and are almost totally self-reliant, We will be the the ones to be left to fend for ourselves – as we always have.
Water storage is very finite and with every roof already having a water tank connected to it. Our options are limited. We have purchased a new, smaller sized, water tank every year now for the past 4 years. Installing those tanks on all the smaller tin roofs on the little sheds, and even the little railway station building has two. Just so that there isn’t any water allowed to be wasted. Once caught and held, then we can use it later at our discretion.
Having thought through the possibilities. We decided to up-grade to a much larger water tank on the barn. The barn has a huge roof, but only a relatively small 1,000 gallon/4,500 litre water tank that we put on there almost 20 years ago when we built the barn, to satisfy the local council building inspectors. We don’t use it for the garden at all. It is there with it’s own independent pump to supply the roof and wall sprinklers that I fitted to the building specifically for fire fighting. As it’s only been used twice in its life. It remains constantly full. However, when it rains and the tank overflows, I have the overflow connected into the plumbing system that delivers the water from all 3 big sheds into the 120,000 litre concrete water tank at the bottom of our block. This is the tank that is now almost empty. I can connect the new proposed tank in parallel with the old one. That way, I only need to do a bit of plumbing.
I realise that I can add a 7,500 gallon/35,000 litre water tank on the other side of the building. This is a significant exercise, cutting a 4.5 metre diameter level base through the top soil and placing 2 cubic metres of fine basalt dust, then spreading it and compacting it to make a solid base for the tank to sit on. I’ve been at this job since Friday last week. The base is done now, so I have turned my attention to the roof plumbing. I need to put in a syphon gutter system to take the water to the other side of the shed.
I wonder why it is that I seem to end up doing these jobs in such hot weather. Answer. every day is hot these days. Summer starts 3 months earlier and goes on for another 3 months longer. We are having 9 months of summer these past few years.
The old saying goes, When is the best time to plant a tree? The answer is, 20 years ago! That is also the answer to when I should have put in this larger tank, but I was already fully committed 20 years ago to installing the water tanks that we already do have now. So now is the best time for this new tank! When it rains again, as it most certainly will. We will fill this tank with rain water and be better off in the future. This is just forward planning!
So, today I’m digging this trench into rock hard dirt that is as tough as concrete. I end up having to use a crow bar and a pick to penetrate the soil. I give up pretty quickly and go and get the tractor to try ripping a groove into the hard packed, baked soil. I end up bending parts of the the tractor and need to go to the toy shop, formally known as the kiln factory, to put the bent and broken parts under the hydraulic press and bend them back into shape. If nothing else, I get to spend a few minutes out of the full sun, in the shade, in the shed, making good the repairs. I love the toy shop! I can fix almost anything in there – one way or another.
By the end of the day, I’m pretty rats, but the hole is dug and the pipes are laid and blue-glued together. The new lengths of guttering should be delivered tomorrow?! I should have it all back together by the day after. It can rain by the end of the week and I’ll be OK with that.
As for the new water tank, well, I haven’t even ordered that as yet. First things first. Watch this space !
At the end of this days tough work, I go to the garden and find that I can pick the first of this years crop of tomatoes. 3 red tomatoes, It’s the 26th of November. I can’t remember an earlier date for the first red tomato of the season. We can usually get a few before Xmas, but this is a whole month earlier than Xmas. If global warming is a communist plot to disrupt Western economies, as Donald Trump claimed, then, thank you to the Chinese Communist Party for these unseasonably early red tomatoes here in Australia. I wonder how they do it?
Maybe every dark cloud has a silver lining? I’d be happy just to see some clouds! Dark or otherwise.
Janine and I were invited to the Powerhouse Museum last week for a special announcement event. There was free wine and a meal, so of course we went along. 🙂 The Powerhouse Museum recently received a substantial bequest, It was announced that 3 glass artists and 3 ceramic artists have been awarded the inaugural Willoughby bequest award.These artists were chosen by the Powerhouse Museum curators to be included in the museums collection because they are or have been making a contribution to Australian artistic culture through their research and creative work. I am very lucky to be one of the 3 ceramic artists chosen. Among all the Australian potters, I can’t yet reconcile that I am one of the 3 lucky ones chosen. It was quite a shock to me I must say. I can only guess that it is because of my 20 years of consistent research and exhibitions enquiring into the nature of native sericite porcelain around the world? I have known about the award for a couple of weeks, but was unable to say anything about it until now, as there was a media embargo until the presentation awards ceremony last night. I’m humbled, surprised and elated to be chosen. The other 2 ceramic artists chosen are; Renee So, a ceramic artist born in Hong Kong, raised in Australia, and now working in London. Nicolette Johnson is a ceramic artist born in London and raised in Texas, but living in Australia now for 5 years.The 3rd ceramic artIst is me. Wow! How could this happen to me? I don’t know! I don’t have a social media presence on facebook, twitter of watsap. I don’t go to openings and don’t do any networking. So I still don’t know how they found out about me and my research. It’s a mystery to me.The other two ceramic artists are young, talented, hip and sassy women, making terrific cutting edge work, who are winning awards and being represented internationally. On the other hand, I probably represent the old fashioned approach to making pots. Fossicking, digging, processing, then ageing the mica based stones that make my work from. It’s not really done that much – if at all, anymore. I grow most of my green food in my garden and orchards. I also grow most of the wood fuel that I use to fire my wood fired kiln and the kitchen stove and home wood heater. I try and do every step in every part of these processes myself, and do it sustainably.
The selection of such varied and different artists certainly illustrates a depth of research and breadth of scope in the curator, Eva Czernis-Ryl’s decision making process. I’m very grateful and pleased to be honoured. I really hope that I can make something that lives up to this onerous responsibility of receiving my small part in this amazing bequest award. It’s such an honour!I did notice that there are 3 men and 3 women, 3 glass and 3 ceramic artists, with Adelaide, Brisbane, Wollongong, Mittagong, Canberra and London represented, spreading the selection around. Because this is called the Barry Willoughby ‘Inaugural’ Bequest Award, it hints at the possibility that there may be other awards at some time in the future…However, I got the impression that it will not be a regular event. Best wishes Steve
Janine and I set up the plastic pipe hoops and installed the netting over the peach tress in the stone fruit orchard 3 weeks ago as the fruit started to appear. These early peach trees develop their fruit so quickly. They swell from buds in no time flat.
We knew that it was time to cover them when we saw parrots in the trees starting to eat the tiny young green fruit. It’s been so dry here as the drought drags on. Actually I don’t believe that it is a drought – an unusual event, that is just bad luck, as the politicians would have us believe. No! I believe that this is the new normal for us in this continuously developing global heating crisis. The rain fall pattern has been changing and our share of the rain has been steadily decreasing ever since we settled here 43 years ago.
We used to be able to get by here in this place with the water that we collected in our dams. We used to get terrific, short, intense rain storms, that would drop 20 to 25 mm. of water in an hour or two. This sudden flow of water had no time to soak into the soil and just flooded down the road in the gutters and then down the ditches that we had dug to harvest that flow, and into our dams. A good storm like that gave us sufficient water to get us through the best part of summer. We don’t get those storms any more, not for a decade or more now. In the 70’s we could get two or three of those storms in the summer months. Sadly no longer.
I have been a long-term subscriber to ‘NewScientist’ magazine, published out of the UK, but we now have our own branch here in Australia these days, with an Australian edition, so the Australian content has been increasing steadily. Over the 45 years that I have been a subscriber and reading the research published on our increasing emissions of carbon into the atmosphere. I’ve seen the steady increase in certainty in the science behind our understanding of the evolving crisis. I’ve also seen the strenuous denials from the carbon intensive industries lobby, building from straight out denial that the earth is warming at all, to now admitting that there is warming, but it is nothing to do with carbon in the atmosphere. All the denial and fake news claims, even the spurious pseudo scientific fake ‘research’ sponsored by the carbon lobby, is straight out of the cigarette industry playbook.
We are drying out here, slowly but surely. We have some peaches on the early peach trees, but there are no apples and just a few pears, as there wasn’t enough cold nights over winter to build up sufficient ‘winter chill hours’ that the fruit trees require to be able to ‘set’ fruit. We did get a ‘set’ of cherries on the trees, but with the exceptionally dry conditions, it has driven the kangaroos up out of the dense bush in the gullies up into our back yard and right up to the house in search of food. They have begun eating the cherry trees lower branches and the parrots have taken all the fruit while it was still green and hard. I’ve never seen that before. These wild animals are obviously very hungry.
In some ways it’s OK, as now we don’t have to worry about keeping the water up to the orchard, as we are very low in water storage. All 4 dams are close to empty. I need to get the portable petrol pump out and pump all the 3 other dams dry and locate all the remaining water into just one dam to minimise surface area and evaporation. We may need that water to fight fires over the coming summer.
At the moment we are OK, we are managing to water the vegetables and the few peaches from our rain water storage tanks, but this is a finite resource. We are already half way through our main large water tank, and we are still in spring! We still have one more large water tank full. That is our reserve supply. We’ll just have to wait and see how things pan out.
With almost every roof on our property already fitted up with guttering and a rain water tank, it’s hard to imagine how we can increase our storage in the short term. We can only double up on our storage tanks to catch the overflow from the original tanks, should there be a big storm – which there will be one day, bit that isn’t going to be any help just now.
For the time being, we have some early peaches to console us and reward us for our efforts.
I was recently in China doing some research. I have written a little bit about that, intermittently, in the last month or so. While I was there, I arranged to get my hands on some new and different sericite samples. These have now just arrived here last week and I have done my first tests with them.
I now have 4 different Chinese sericites to compare.
Although it isn’t immediately obvious from the image above. If you look closely, there are 4 different colours of rock samples from top to bottom, white, cream, grey and pale buff. They all look more or less white, but they each have various tints or shades of colour to their whiteness. They all do have one big thing in common. They all throw badly, the palest ones being the least plastic and most difficult. They feel a lot like my local Mittagong porcelain stone, only better behaved.
I felt like I’d gone all the way around the world and come home again when I threw these tests. They felt so familiar.
I’m really looking forward to seeing the results fired. I had a bit of trouble with the usual shrinkage and drying cracking problems, but I did get some of them through successfully. But I lost quite a few. Still, nothing that I’m not used to, and I’m getting good at recycling the turnings and failures.
I almost filled the tray on my old wooden kick wheel with turnings after trimming just 12 small bowls. I must be removing at least half of the weight of the original material to get them thin enough to look and feel like porcelain. I aim for 2mm at the rim and 3 mm lower down, graduating 5mm at the foot. This tapered wall thickness allows the best translucency at the rim and higher up the pot, while retaining sufficient strength to hold the pot up against gravity while it sits at 1300oC in the kin to develop enough glass in the body to be come translucent.
If I’ve done it right, the whole finished, fired, ceramic mass, has the correct quantity of primary and secondary mullite crystals to glue it all together, while becoming glassy enough to allow plenty of light to pass through.
Too glassy and/or too thin and it slumps. Too thick or not fired high enough and it stands up straight, but isn’t very translucent. It’s a bit of a fine line to tread.
As I sit and grind away at this damp, ground-up rock dust with my tungsten carbide tools, I realise that I’m truely happy doing just this. There is a gusty wind outside, but I’m in here sitting in the sun and I don’t want for anything more at this moment. This is fun. I can’t wait to get them into the kiln.
It has all the promise of something special about to happen.
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.
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.
