Sericite Journal – Seoul Searching

I have arrived in Korea to spend some time refining my interest in sericite porcelain stone, researching and making a few pots too. I am spending the first few days in Seoul to begin with to catch up with a few friends.

I spend the first day wandering around to get my bearings and just seeing what turns up. I spot a very narrow door tucked into a small corner between a department store and a clothes shop. I investigate and it turns out to be a tiny restaurant .

Every little space is utilised!

I meet up with my friend Ms Kang and her partner, she takes me to a part of Seoul that I haven’t been to before. It’s the trendy ‘hip’ part. There are a number of streets full of eateries. In the evening, after work, all the restaurants spill out onto the streets in fine weather. It’s May and the weather is balmy, so every space is utilised. We spend the night walking the streets looking for a ‘cool’ wine bar that she has read about, but don’t find what we want. We walk down many laneways, dingy small alleys and descend into dimly lit basements or up flights of stairs to single darkened rooms, windows blacked out. Rooms that might once have been small office spaces, and presumably very cheaply rented. They masquerade as ‘hip’, ‘cool’ night spots now.

IMG_5349 

We find three wine bars. But they are all up-themselves with too much ‘cool’ and not enough wine! The wine is priced at a ridiculously expensive rate, for unknown cheap Chilian or South African quaffing grade vino, you have to buy the bottle, there are no tasting notes, or a price by the glass. We are in a group and against my better judgement, the consensus is to buy a bottle. The owner goes to great lengths to decant the wine into an airing flask. It’s all so pretentious. This wine has nothing to loose to the air, it doesn’t need airing, no aroma. In fact the sulphates are the only flavour it has. It has no nose, no taste and no finish. It’s completely flat throughout. I’d rate it as a $3.00 ‘Aldi’ cooking wine. Pity we had to pay over $60 to find out. I offer to pay, as these people are my friends, But Ms Kang is very generous and covers the bill, speaking in Korean to the bar owner, telling him to ignore my plastic card and take hers.

Lesson, don’t bother going to a Seoul wine bar. We are so spoilt in Australia with so much affordable, good wine to choose from. I’m guessing that wine tasting is new to Seoul. The next day I find some Australian wine for sale in a small local convenience store, so I buy a bottle that I recognise from home, I buy it as a present for my friends. It is not top notch, but I know it and know that it will be 10 times better than the ‘vin ordinaire’ that we were meant to appreciate in the bar. Had the wine been OK, the ambience was quite interesting in a retro kind of way. All candle lit, it reminded me of the beatnik clubs of the late 60’s.

The next day, I’m off to the Ewha Womens University, where I’m to meet a professor of Ceramics. We are organising for me to do some teaching to her students. Ewha is the oldest university in Korea, as I understand it. It’s a nice campus with a mixture of new and old buildings. Open and seemingly spacious, as the most modern example of its architecture is entirely under ground, leaving a large space above for gardens and greenery. Every little space is utilised! I like it. I am invited to give a presentation of my research to the students.

In the afternoon, we wander the old market district. I seem to find myself in what feels like a kilometre long avenue of dried fish stalls. It goes on and on and on! I’ve never seen so much dried fish.

IMG_5370    

Then it’s the chilli isle.

IMG_5383    

Though the dried vegetables whet my appetite, I don’t buy, as I have nowhere to cook. Then through the food hall isle and into the fashion lanes.

  IMG_5394  

I find some very nice open-weave natural ‘ramae’ fabric, and although I’m tempted, I resist. I find a ready made, long sleeved, ramae shirt, but it costs a lot more than I can afford. Over $150. If it were my last day here and I still had some money on me I might be tempted, but this Is only my 3rd day and I haven’t done any work yet, so I need to make my budget stretch.

The next day, Ms Kang takes me to icheon, the potters village, to visit my friend Lee Jun Beom. It is the May Ceramics Festival time and all the studios have their stalls out. There are some very impressive pieces, some less impressive and some amazing miniatures .

IMG_5418   

I was quite taken with the ‘fake’ irridescent blue oil spot tenmoku. I imagine that is was made by painting on the dots with something like a bismuth lustre?

IMG_5419

It is a really interesting day, aimlessly wandering from shop to shop, studio to studio. The last time I was here, my friends took me to the local Ceramic Art Gallery and Museum. In conversation with the Director, it transpired that my research was of interest to him. He asked to see my work. I only had small images on my phone to show him. I didn’t come prepared to represent myself. I was taken off guard. My friends talked me up quite a bit to him it seems. I can’t speak Korean, so don’t know the content of their conversations, but it transpired that he became interested in collecting a piece of mine for the international section of the collection in the Museum. Regrettably, we didn’t seem to wander to that part of town on this trip. However, instead, we found our selves somewhere completely different.

I walk into a small studio, quite unpretentious, there is nothing outside to give the game away. Suddenly, I realise that I know this work. I recognise it. I’m sure that I know the maker. I have met her before. In another place and at another time. I’m almost certain. This lady does the most intricate carving on porcelain. I saw her demonstrate two years ago at the Yanggu Porcelain Museum Conference. I was very busy at the time, demonstrating and preparing give my own presentation, so I only had time for a cursory glance around the demonstrators. Janine had more time and got to speak to this lady at length. Her name is Shin Lee, going on her visiting card that I can see on the table. Luckily she can speak some English.

I walk up to her with my friends and say that “I think that I know you from Yanggu.” She replies straight away. “Yes, is your wife with you today”!

How amazing is that? She remembered meeting Janine and speaking with her from two years previously. This potter, or should I say artist/carver/decorator is a real master! It appears that her husband throws the pieces and she incises the intricate images, particularly of Hydrangeas.

  IMG_5457

I like her heaps, it’s a real joy to meet her again. She is lovely and her work is impossible to fully appreciate until you get up close and handle it, feel the intricacies, appreciate the subtleties of the carving that highlights the shading effects of the bass relief carving. Again, If this were my last day, I’d buy a piece, but my suitcase and back pack are already chokers with stuff that I need to unload when I get to Bangsan.

I haven’t even reached Yanggu yet, so my cargo of porcelain pieces that I made at home during the last 12 months from the ‘borrowed’ Bangsan sericite porcelain stones takes up a lot of space and weight. I’m returning the stones I ‘borrowed’ as finished pieces, shaped from the 100% Korean sericite, crushed, milled and made plastic in my workshop. I transform them from mere stones, into porcelain clay body, by crushing, grinding and milling them into a wet, plastic, malleable clay-like substance. I form them into pots on my old wooden potters wheel, then bisque and glaze fire them into permanence. I glost fire them using pure Australian sunshine, glazed with my own porcelain stone celadon/guan style glaze made from my local weathered white granite glaze stone, enhanced with the addition of some local kangaroo bone ash. I’m donating the pieces to the Yanggu Porcelain Museum as a gift that represents the meeting of two minds, myself and that of Mr Jung the Director of the Museum. 

As both of our cultures enjoy drinking beer. I see it as a ‘Cultural Shandy’. A contemporary melding of Korean and Australian ceramic cultures. Well, that is my take on it anyway.

IMG_4863 

IMG_4864

I signed the bowls with both my usual initials stamp, my workshop seal, but also the ‘Yanggu’ chop in Korean lettering, to identify its true origin. It represents the journey from Bangsan to Balmoral and back again.

The next day, I spend some time in the Namdaemun market area of Seoul. There are some astounding figures quoted about the number of stalls and number of visitors that the area gets each day. The market site is a very ancient one, but during and after the Korean War, there was a thriving black market in renditioned military goods. The economy was in ruins. The country was largely destroyed. Society was in turmoil and almost everyone was living in hardship or poverty. The market offered a way for the necessary transfer of goods, services and information in an informal and I believe quite efficient way. The site has persevered and sustained itself through necessity, it’s quite simply very popular. Even as the concrete high rise of the city encloses it, it still continues to exist. I wonder how long a market like this will survive against the pressures of development?

I wander the very narrow and intensely interesting back lanes. I come across a narrow lane of kitchens. Every one calling to me to step past and around the hot stove and into the seated area to have a very freshly prepared lunch. It’s enticing, but it’s also only 11.30, so a bit early for a cooked lunch. Instead, I take a photo and keep walking.

IMG_5471

IMG_5470

  

I eventually decide to buy a small ‘Panjun’ style round handheld pancake. Korean style walking fast-food. I choose this place simply because it has a queue of 30 people waiting to buy one. If the locals are prepared to queue and wait for it, it must be good. Or so my thinking goes. This time last year, when I was in Seoul, I had a meal in a restaurant with loads of other respectable citizens at lunch time peak hour in Insadong. I knew as I ate it that something wasn’t right. As I left, I felt quite unsettled in the stomach, half an hour later, I almost blacked out, got quite dizzy and threw up in the street at the bus stop. Janine and I shared the meal together. However, I was the only one to eat the pickled chilli relish in the jar on the table, Janine didn’t. It was a respectable, busy restaurant, in a posh part of town. How can you tell?

I’m pleased to repot that the pancake was delicious, followed by no unpleasant side effects – and only $1 great value!

    IMG_5475

IMG_5478

While I’m here in this place where so much is possible, I decide to get one more name stamp carved with my initials. I find a tiny shop with a young lady that does such things and draft out my design, but regrettably, she doesn’t get it or doesn’t care, or perhaps she has no inherent sense of design flare? I don’t know. But my own hand-made wooden stamp that I cut myself at home has a better look to my mind.

Mine is a bit wobbly, but looks better overall. However, it doesn’t really matter, as it is so small and is only on the foot ring, such that no-one will ever really see it.  

The next day I leave Seoul and take the train and bus to Chuncheon where I am destined to meet up with the director of the Yanggu Porcelain Museum. I have texted him an image of my buss ticket, so that he will know where I am and at what time. 

Over my 5 visits to Korea, we have become friends. United by our common interest in sericite porcelain.

On this visit, my fifth, I am invited to stay with Mr Jung and his wife in their home. I’m flattered and feel really honoured by this gesture of generosity at a very personal level.   

The next day it’s down to work in the Porcelain Research Centre. My time is limited, so I must get busy. The Yanggu Porcelain Museum is situated in the tiny village of Bangsan right up near the DMZ, in the geographical centre of (the unified) Korea. The site has a history going back 700 years. ‘Sericite’ mica has been mined here for that long. Sericite is otherwise known as ‘Porcelain Stone’, ‘Do-suk’, in Korea, ’Bai-tunze’ or ‘Pai-tun-ze’ in China, ‘Groan’ in Cornwall, sometimes ‘Muscovite’ Mica or ‘white mica’ in Australia. This is the stuff of the original porcelains that were independently discovered and developed, long before kaolin and felspar was added into the mix. It seems that porcelain was invented wherever sericite was plentiful.

The Museum here has several bodies available. All based on sericite, most of them are  available to be used individually, but the Porcelain Centre also has a couple of blended bodies that are much easier to use. These are prepared for use by the part-time students and visitors who come on cultural tours. The blended sericite bodies have been cleverly developed by Mr Jung to over-come the various short comings of each of the individual materials. 

There is a 2 material blend that combines a very low temperature maturing mica With a more refractory one. Individually they need special attention and different firing temperatures, but combined they work very well together. There is also a 3 way sericite blend. These blends have the advantage of all firing at the same temperature, which makes life a lot easier for the staff. 

Like me, Mr Jung, the Director of the Porcelain Museum, has a life long interest in sericite porcelain, He being born and raised here in Yanggu County.

They no longer use the original mined sericite from 700 years ago. The mine site is now lost. No-one knows where it once was. I suspect that it is probably over the border in North Korea a couple of kilometres away to the North. Just over the hill from the Museum. There is however a site, closer to the border, where the mined sericite or Do-suk, was sorted  into different grades and stored, before being carted down the valley to the river to be shipped to Seoul and the Royal Porcelain Works. Ancient documents name the site and list how 70 tonnes of material was shipped out in each 12 month period, usually in spring and autumn, at high water, when the river was not either in flood or dried up.

I have visited the ancient storage site on 3 occasions to investigate and collect samples for my research. I have had my samples analysed at the University of New South Wales in Sydney. The results are published in my recent book ‘5 Stones’. The ancient material is indeed almost pure sericite with some silica. It is beautifully plastic to throw on the wheel even without ageing. I was thrilled to discover this when I got my box of stones home and processed them into a plastic body.

There isn’t much to be seen these days. And I wouldn’t know that it was there, except that I was shown the remote site. On my last visit, I arrived just after torrential rains had caused havoc in this part of the country. On arrival at the site, I found that the rain had caused some quite deep erosion in the gutters of the dirt track leading up to the site. Because I knew what I was looking for, I was able to identify small white fragments of the stone that had washed down the road in the gutter. I rescued these, washed and cleaned them, and ‘borrowed’ them to make the work that I am now returning to the Museum as fired pots.

No-one here seems to be interested in collecting ‘in-situ’ materials for making ceramics. It’s not taught in the schools or Universities here, so no one knows how to do it. Added to that is the fact that you can buy almost anything you want already prepared from a pottery supply shop. There is no incentive to try unknown and untested wild materials.

I’m lead to believe that I am the only person to attempt to make work from these ancient stones in the past few hundred years. All the current sericite comes from an industrial sized mine site a few kilometres away up the river. Korea it seems is very geologically rich in Sericite sites.

However, things may be about to change. Since I was here last. Mr Jung, the Museum Director, has taken an interest in my research and reads my occasional emails about my prospecting and mineral processing with interest. He was recently out bush-walking in the hills behind his home and has discovered what he thinks might be a seam of sericite in the side of a road cutting used by loggers. We have hatched a plan to go up there and investigate. We will go as soon as I have finished throwing and turning my pots. Perhaps while they are drying prior to bisque firing.

So far I have tried the two blends and 3 individual sericite bodies that Mr Jung has prepared. There are two new materials that I haven’t seen before. The raw material appears just off white when raw and dry, but develops into a beige to khaki colour when wetted down. The other is slightly pinkish when raw, but develops into an apricot, to pale terra cotta colour after processing. They are both quite plastic to throw, the apricot one has a tendency to split though. I feel that a little addition of ‘Calgon’ to the slip during processing might help ameliorate this?

I have seen the fired samples and they both seem to be good, firing just off white, but not too translucent. I think that they may be quite good in wood firing, with the lowish iron content, they may flash well.

IMG_5503

The view from my room in the early morning, just after sunrise at 6.00am is not a Shepards Delight, but just a sign of the filthy air quality here, and this is way out in the far countryside. Hours away from the centres of heavy industry and Seoul. The locals claim that all this  polluted air is blown over from China, and some of it probably is, but Korea is a highly industrialised country with a majority of cars and certainly all trucks being diesel powered.   My Jung and I are in agreement that the origin of the pollution is probably somewhere around 50/50. Whatever the origin, the air most certainly has to be cleaned up. People will be dying young with lung diseases growing up breathing this toxic mess.

World wide, we need to phase out diesel engines and coal fired power stations as an easy first step to cleaning up the environment. I say easy in this case, simply because there already exist cleaner alternatives such as solar and wind power to generate electricity. Of course it won’t be politically easy. The UK spent a whole week this month, May 2019,  with all its coal thermal power stations off line, relying entirely on its non-coal sources of energy. It can be done now.

Of course there will be screams of denial, loads of hand wringing and calls for extensions by the very powerful vested interests and their political allies who get generous ‘black’ donations from the carbon intensive industries. The Murdoch press will wail and nash their teeth, publishing hysterical headlines, based on untruths, if the past is anything to go by. 

Change is over due, Cleaning up our environment has to be done. We desperately need to clean up the disgusting mess that we have made in this generation. It’s our responsibility to start to fix what we have largely broken. The climate crisis has already gone too far.  We are going to need a combination of government regulation and free market solutions to claw back the global heating to manageable levels. Profitable business opportunities await the entrepreneurs who dare to make the change and forge the way. The broken old vested interests are simply being lazy. It’s time for them to step aside, stop holding us back and let the future begin.

Sunshine Came Softly Through My Spy Hole Today

This is the research paper that I presented to the recent Ceramics Triennial Conference in Hobart, Tasmania.  On the ‘Sustainability’ Panel.

Steve Harrison – Sunshine Came Softly Through My Spy-hole Today.

I was raised in the 50’s in a home where the topic of ‘health foods’ and ‘natural living’ was at the forefront of conversation. I came from a loosely quaker/buddhist background with a grounding in ‘healthy’ living. As a child, I was brought up in this environment. Aristotle said “give me the child until he his 7 and I will give you the man”. I am that man. A ‘greenie’ before the greens were invented.

IMG_0162 copy IMG_0172 copy IMG_1067

Since I decided to be a potter, I have always been a wood firer using a small, single chambered, bourry-box kiln. I wanted to fire my pots as cleanly as possible, in an environmentally sensitive way. In 1976 I moved to the country and bought a very old derelict school building, built in 1893, with seven acres of land and started planting a forest. By growing my own trees, these trees took their carbon out of the air, when I eventually burnt this timber to fire my kilns, it didn’t introduce any new carbon into the atmosphere. This was the best approach that I could think of to minimise my carbon footprint at that time.  I’ve progressed!

We have also planted very large vegetable garden and 5 small themed orchards, with a dozen cherry trees, a dozen almonds, a dozen hazel nuts, a dozen citrus, a dozen stone fruits, a dozen apples, 5 avocados, 4 truffle oaks, 3 white figs, two berry vines and a bower bird in a pear tree!

My wood fired kiln has proven to be very fuel efficient, I have worked on the design for over 40 years and written the standard text on the subject. ‘Laid Back Wood Firing’ and it is as clean as a wood fired kiln can probably get, without using an after-burner. I tried adding afterburners to several kilns, but have since abandoned that idea as too wasteful and complex. There is no point in using a premium fuel like LP gas to burn the smoke from an inefficient wood fired kiln. I couldn’t justify it. So I stopped working on that project.

IMG_2352 copy  Brooki flame tube copy IMG_0674 copy

I did a lot of work on ‘flame tubes’. Fibre lined stainless steel tubes on top of the chimney that allows warm air in at the base, so that it mixes with the unburnt smokey fuel during reduction and combusts with-in the tube. All that is seen is a pale red glow at the top and bottom. The beauty of it is that it has no moving parts, and needs no external fuel source.  The blue haze at the beginning of firings has always bothered me and flame tubes don’t fix that problem. That is a work in progress.

It is possible to fire in reduction at high temperature with very little smoke, but the cold blue haze at the beginning of the firing is a very difficult problem to overcome. It was only later that I came to realise that it isn’t just blue haze smoke at the beginning of the firing when we are releasing ultra-fine particles into the atmosphere from our wood kilns. Wood firing generates loads of fine particulate matter, all through the firing. Some of these are quite fine and are hazardous to inhale. They are known variously as PM 7’s to PM 2.5 particles, they are small enough to enter deep into our airways and lungs and can cause all sorts of unpleasant health effects, even cancer.

Clearly, one kiln, fired intermittently, isn’t the problem, but when it is added to the other emissions of diesel vehicles, wood heaters and industrial pollution from factories, cement works etc. It adds to and is part of the larger problem.

See the EPA web site.   https://www.epa.sa.gov.au/environmental_info/air_quality/assistance_and_

advice/smoke_from_domestic_heating.

Added to this less-than-up-lifting scenario, there is the growing problem of global warming. Contrary to the statements of conservative politicians and the hard right media shock-jocks, the science IS settled and has been for a long time. The man-made global-warming deniers are simply wrong! They are either being disingenuous or choosing to be ignorant. Perhaps I could be generous and say that they are choosing different truths.

We used to be able to fire for 8 or 9 months of the year at home, but over the past 42 years, living in the Southern Highlands, our window of opportunity for wood firing has been reduced now down to 5 to 6 months, May to August. September is now getting too unreliable to book wood firing workshops. We have had to cancel workshops in the past few years due to hot, dry, windy weather and therefore total fire bans, as early as September. Total fire bans in our area used to only occur in January and February.

Some time ago, I decided to develop a series of small portable wood fired kilns that could be wheeled out, packed and fired in one day. Then wheeled back away again until the next firing. These portable little wood kilns are very fuel efficient and can reach stoneware temperatures in 3 to 4 hours using a wheel barrow of wood. If you are careful, they can be fired very cleanly. They are a fun solution to minimising carbon emissions and avoiding the use of gas and coal. By collecting fallen branches from around our block, we can fire with a zero carbon foot print. This is the ‘vegan’ equivalent of wood firing . No trees were hurt to fire the kiln. The trees drop the dead branches. We have to pick them up to mow the long grass. We have to mow to reduce the fire hazard in summer. So fallen branches do not introduce any new carbon and are tree friendly. That’s nice, and the kilns are quick and fun to fire. But particulates are still a problem.

So where is all this leading? I realised that I needed to find another way to fire my work cleanly and efficiently into this uncertain, carbon constrained, globally warmed, future. The climate is changing, so we must change with it. Janine and I have had solar hot water for over 30 years and Solar Photo Voltaic panels on our roof, for the past 17 years. We installed 3,000 watts of Australian made, BP Solar, Photo Voltaic panels as soon as we could afford to do so in 2006/7.

Our first solar panels, with the netted vegetable garden with small vineyard and orchard.

We have been using our electric kiln for all our bisque, earthenware and oxidised stoneware firings ever since then and have always paid the little extra for sustainable green power since it became available. So that if we needed to draw power from the grid, it was sustainably generated power that we used. In the last couple of years we have been working towards firing our work in the summer months of fire bans, using a new low-thermal-mass electric kiln that I built from a pile of spare parts, left over from my kiln building factory, after I retired. I designed and built a kiln that is fired using our solar panels and backed up by our Tesla Powerwall II battery.

IMG_3738  IMG_3745  IMG_3817 IMG_0358  IMG_3991 IMG_3990

To allow us to fire in reduction, I made allowance to install 2 small pilot burners in the bottom of the kiln and built a small flue hole in the top. These burners aren’t used to fire the kiln at all. They are too small. The kiln fires to stoneware on solar power, the burners are only used to create a very small amount of flame to generate the reduction atmosphere needed to change the glaze colours.   I attach the burners to the kiln and light them when the kiln reaches 1,000oC. They use about 200 to 330 grams of gas to reduce the kiln load of pots steadily over a couple of hours while the electrical elements heat the kiln load of pots. It’s the best solution that I can find at the moment to give us reliable, all year round access to reduction firings that are very, very, low carbon and as sustainable as I can make them.

IMG_4412

The firing can take as little as 4 to 5 hours in total and give perfectly adequate reduced results. Experience with this kiln has shown that we can achieve all the normal reduced colours with our standard local milled rock glazes. I fire the pilots on 5 kpa gas pressure, but have recently experimented with pressure so low that the regulator gauge can’t register the flow and the kiln still reduces. We usually wait to start the firing until around 9 or 10 am, as that is when the sun is up high enough to give us the energy that we need to get the kiln going. It takes about 2 to 3 hours to get to 1000oC, then I attach the pilot burners and start reduction, around noon to 1 o’clock. I reduce for about 2 to 4 hours depending on what I’m experimenting with and finish the firing between 2 and 4 pm. as the sun is going down. We fire directly off the PV panels until 1 or 2 pm, then as the sun passes its peak, and the kiln is drawing its maximum power. The Tesla battery cuts in automatically to make up the short fall to finish the firing. If the weather is cloudy we can also draw down on our credit with the power utility. As we are on a ‘net’ metering system, and are always in credit. We never actually ever pay for any power that we withdraw from the grid. However, it is important to note that we pay the extra to contract to only use green power from sustainable sources when we do with-draw.

IMG_4187  IMG_4188

I don’t know if you have ever seen one of these graphs?   It is the screen from the Tesla mobile app that tells me how much solar power I’m producing and consuming and/or selling/buying from the grid.The yellow area indicates the solar power generated. As you can see the solar energy starts off low at 7 am, then from 10.00 am it quickly rises to a peak at noon, hovers for a while, then drops away until 6 pm. and sunset.The green area is the energy required to re-charge the battery from its use since yesterdays sunset and running the house over night. This re-charging is usually complete by 9.00 or 10 am.The blue areas of tiny upward spikes is the fridge turning on and off regularly over night and all through the day. The sharp blue spike is the electric jug and toaster being used at breakfast time. On this day it was at 7.00 am. The white area below the line is the energy that we sell to the grid every day when we are not firing the kiln or charging the car. This generates a credit that we can draw down on in cloudy weather and covers our daily charges. This report tells me that I generated 35 kW/hrs of solar and used just 1.4 kW/hrs to run our home and pottery on that day. We sold 32.8 kW/hrs to the grid. It was obviously a quiet day with nothing much going on. I wasn’t welding in the kiln factory or ball milling rocks and pugging clay in the pottery.

IMG_4281

This is what a firing looks like, We simply stop selling our excess to the grid and use it our selves. The blue block is the amount of energy used to fire the kiln. The taller blue spike on the left, is the car being charged at the same time. It is worth noting that we can do both at the same time and still recharge the battery after wards in the afternoon.

IMG_3964  IMG_3965 IMG_3963

Just as an aside, we also have a solar powered electric car. A Hyundai, Ioniq, ‘plug-in’ electric car. I have written about this on my blog on a few occasions with regular up-dates to let readers know how it’s going. v< https://tonightmyfingerssmellofgarlic.com >

IMG_4102

This is what happens when we charge our car. We simply stop selling our excess to the grid for 2.5 hrs. There is enough power to do this, even on a cloudy day, as is the case in the chart above.

We put our pots out in the sun to dry. We call it the ‘solar drier’. The solar drier makes sure that the pots are totally dry before bisque firing. We can charge the car as well in the back ground, both using sunlight at the same time! It’s amazing that there is enough sunshine to go around! The vegetable garden keeps growing and the orchard thrives! We can also walk and chew gum at the same time.

IMG_0635 IMG_1047

To help make this all happen, we recently bought into a community bulk purchase scheme and installed another 3,000 watts of Australian built solar PV from ‘Tindo’ in Adelaide. This allows us to run our house, fire our kiln and drive our car, all on our own sunshine. It’s a very nice feeling to be able to live, cook, work and drive, powered almost totally from our own solar power. We do all this and still have a little excess to sell to the grid. This covers our daily charges to be connected and even earns a little bit of extra cash. I haven’t paid an electricity bill for 17 years. You can see from our recent bill that we do all this and still use about half of what a single person household uses, and much less than half of what a two person household like ours uses.

IMG_4797

Now, I know that someone is going to ask me what is the cost benefit analysis? It’s the most common question that I get asked along with the statement, “I wouldn’t put solar power on yet. you can’t make any money out of it!”Well, my answer is, when you bought your new car. How did you make money out of that? Or, when you flew to Bali for a holiday, How did you make money out of that?

The point is that I did this because it pleased me. I get a lot of satisfaction out of it. I did it to extract myself as far as is possible out of the coal and oil economy. I didn’t do it for money. I do very few things in my life solely for the money. I’m not very interested in acquiring ‘things’. This is the equivalent of my holiday in Bali, or my ‘walking tour of the vineyards of Provence’. I’ve never been to Bali, or walked the vineyards of Provence. We each choose to spend our discretionary dollars in our own way. This is mine.

Now finally, I will add that I bought carbon credits to cover the carbon off-set of my flight here. Real off-sets in the form of planted trees. I buy a few hundred dollars worth of carbon credits each year to cover all the damaging things that I do to the environment in my life, like air travel. I think that it is worth it. I’m not proselytising for solar. You will have already made up your own mind about that. You’ve had a couple of decades to consider it. I’m just telling you what is possible, because you won’t have heard it from the the Federal Energy Minister or any one else in the government. This however, may be food for thought, if you haven’t already though about it. I will end by telling you that the future is here and this just might be what it could look like.

Autumn Draws to a Close and the Cooler Weather Arrives

As autumn draws to a close we have been in and out, travelling to the National Folk Festival, listening to some very good music. Then, recently I was speaking at the National Ceramics Triennial Conference, where I delivered a paper on sustainability. In between, as always, we were in the pottery making and firing our pots, both before, in between and after these events. Making pots and growing food are the two constants in our life.

 

We were also in the garden planting more veggies for the cool weather. The tomatoes are still hanging on with just a few tiny fruits ripening every few days, so that we can have salad sandwiches for lunch with our lettuce from the garden. The garlic that I planted in March is up and doing well. I planted 5 small beds of about 50 cloves each. A smaller crop this year. I was busy and didn’t find the time to get more in. I have planted another 100 cloves today. Maybe a bit too late to do well, but this is real life.

  

Tonight we will have baked vegetables, yesterday it was minestrone, with everything from the garden. Our gardening efforts feed us well.

I planted a couple of new avocados a few days ago. One more type A and another type B for our collection. We now have 6 different varieties. When these trees mature in a few years time, we will have a much longer cropping season and bigger harvests. The chickens love to get involved in any event that involves fresh dirt. They hop in and excavate the hole a little more, but then hop out and start to fill it in again. The don’t get it! but they have fun doing it and their eggs have super, deep, rich, yellow yokes.

 

The latest young avocado tree freshly planted with its with mesh guard to keep the kangaroos from eating the top out. As they most surely will, with any new tree that we plant in the orchard. They can’t resist having a taste of what ever is new. You can see the original 40 year old avocado tree behind the this new one. and the bare branches of the leafless cherry tree to the right.

The peaches are loosing their leaves, the cherries have finished and are barren, the apples and pears are turning yellow in preparation for the fall.

 

In the evenings it is cold enough now to start to light the fire every night. We sit by the fire and shell our dried beans. We shell them and then dry them out fully in the oven after we have finished cooking dinner. This extra heat ensures that they are fully dry and won’t go mouldy in the jars in the pantry. It also kills any little bugs and critters that may have bored their way in to the shells hoping to hatch out and consume the lot over winter. They are ideal for minestrone.  We will make many lovely wholesome meals out of them over the winter.

Driving on Sunshine – 3 month up-date

Driving mostly on sunshine is very fuel efficient!

We are just home from spending the Easter Long-Weekend in Canberra at the National Folk Festival. 5 Days of great music, camping out under the stars, catching up with old friends and drinking some very nice pear cider.

We drove down and back in our new plug-in, Electric car. The Hyundai Ioniq plug-in. Canberra is roughly 200 kms. away, so we drove the first 1/4 or so on sunshine and the rest on petrol. We get around 65 to 70 kms on a full charge of sunshine from our solar panels at home. This distance varies slightly, depending on how hard you push the car (I don’t ) and how much regenerative braking that you do, as regenerative braking re-charges the battery from the energy recovered from the braking system.
Instead of applying pressure on the brake shoes in the wheel hubs to slow the car. Regenerative braking engages the electric motor and uses it in reverse, so instead of using electrical energy to propel the car forward. The forward energy of the car is used to run the generator to charge the battery and this drag on the system slows the car. The disc brakes are only engaged when you press very hard on the brake pedal, such as in an emergency.
The car automatically swaps over to petrol when the battery charge gets very low, always preserving just a little battery power in reserve for when the car is just cruising and doesn’t need a lot of oomph to get along. Braking, when going down hill, recharges the battery, so the car is intermittently changing between electric mode from the battery and the internal combustion engine all the way along the trip.

Before setting of for home, I check the dash to see that we have a driving range of 111 kms, but home is 200 kms away, so I decide to buy some fuel.

IMG_5075
We have travelled 3,788 km in this car since new and we have put $50 in the tank so far. I can see that we still have 8% left in the fuel tank.
We fill up in Canberra before the long drive home and put in 36.95 litres into the tank, at $1.45 per litre.
On the way home Janine calculates that we have travelled 2,138 km on our first $50 tank full of fuel.
So this seems to indicate that we are averaging about 1.7 litres per 100km.
It crossed my mind when I bought this car that I would be able to achieve a bit better than 2,000 km on a full tank of petrol, and so it seems that we have done it.
We arrive home via the shops in Mittagong and are just short of 4,000 km on the odometer.
The first thing that I do when I get home is plug it into the solar PV system and re-charge the battery fully, ready for the next trip.
When we are driving locally, we mostly drive on 100% sunshine. The battery is sufficient to get us to the shops and back in any direction that we need to go.
We only use petrol when we go on long trips like this one to Canberra, or to Sydney, the South Coast or The Blue Mountains.
At the end of each trip, when I switch off the ignition. a small window in the instrument panel reports on the latest trip.
IMG_4815
This trip was 33 kms and I used 0.6 litres per 100 kms. Which means about 200mls. I’m not entirely sure as yet why the petrol engine fires up at unexpected times, even though I have chosen fully electric mode. I believe that it is something to do with charging up the 12 volt battery, that is used to power the dash, computer, air-con, head lights and other things that don’t involve moving the car forward.
We have achieved these very fuel-efficient figures in our driving, because we always drive steadily, and evenly, avoiding sudden stops and fast take-offs. The on-board computer tells me that we are averaging 390.64 kilometres per litre of fuel. This is because we usually drive mostly on sunshine.
The info below is down-loaded to my phone on the 1st of each month. This report is for March and doesn’t include the Canberra trip.
It is a very rewarding feeling to be able to drive mostly on sunshine. It fits in with our philosophy very well. This isn’t about saving money on fuel. This is all about attempting to live an ethical life with a low-carbon foot-print. Extracting our selves from the coal/oil based carbon economy as much as possible. It started 30 years ago when we stopped driving our old, but reliable VW beetle and bought a small, 3-cylinder 900 CC. engined, fuel-efficient Daihatsu car, slashing our fuel consumption, and then 12 years ago when we installed our first solar panels. Two years ago, ordering the Tesla battery when it became available in Australia.
Now we are driving on sunshine – well mostly!

Improvised Cannoli

I have relatives coming to stay and I really like them. We don’t see them often enough. So to celebrate their stay with us. I try and make an effort. Something different for change!

My niece is of Italian heritage and so I choose to make my bastardised version of Cannoli de Sicillianna.
It sounds impressive, but I don’t have any of the ingredients.
The recipe that I use comes from a book about opera by Antonio Carluccio. It is all about foods that are suitable accompaniment for opera.
I remember seeing Rick Stein on the idiot box doing a special on food and opera. I didn’t get it. I thought that he was stretching a long bow.
Anyway, I saw this book by Carluccio in a 2nd hand book shop, maybe 20 years ago and bought it.
It has a recipe for cannoli (P76), but I can’t bring myself to follow it. Apart from the need the make the tubes from scratch and deep fry them in lard!
I don’t even have any of the ingredients except the ricotta.
The recipe calls for ;
500g. ricotta,
100g. super fine sugar
1 tbsp. vanilla sugar
2 tbsp. orange flower water
50g. candied orange peel
50g. candied lemon peel
50g. candied citron
50g. glace cherries
50g. candied angelica
80g.bittersweet dark chocolate
and icing sugar
I can buy ricotta at the local shop, only a 10 km trip, but have to drive the 50km into town and back to buy the glace cherries at the supermarket.
All the other ingredients look pretty exotic.
You get used to living in the country and making do, so I improvise.
I am only making one dozen of these little cakes, so I halve the quantities.
I’m not into deep frying in lard, so instead I make some little tartlet bases and blind bake them for 15 mins.
I use the few dried fruits that I have in the big stoneware jar in the kitchen for making our muesli. Then instead of orange flower water, I decide to use finely grated lemon and lime zest, plus the juice of half the lime. Janine has some vanilla paste in her cooking cupboard. Instead of all the exotic candied fruits, I use my dried fruits muesli mix and instead of bittersweet dark chocolate I substitute half a dozen tiny ‘Aldi’ dark chocolate easter eggs finely sliced. After all, it is Easter.
 
It actually works out really well. They look rough but they taste delicious.
Funnily, they didn’t turn out like the picture in the book!

Two Flans and Marzipan, from Two Music Fans

Janine and I have just enjoyed our first house concert of the year.

We spent an afternoon with Lindsay Martin and Victoria Vigenser – again!
We had them here with us in our home last year and they were terrific, such beautiful music. Lindsay is an amazing fiddler.
They work together so well.
A wonderful afternoon well spent.

We are starting to eat into our summer preserves. We have been enjoying sliced peaches, plums and pears recently.
We have just started to open our jars of preserved whole peaches. These were bottled in December and vacuum sealed into ‘Fowlers’ jars.
IMG_4769
IMG_4771 IMG_4779
Having been heated in a light syrup to seal the vacuum in the jars, then stored for 4 months in the pantry. These whole peaches are just starting to develop that wonderful marzipan flavour that they get from the stones.
We have also been cooking a few cakes to keep the colder weather at bay on dull days. Janine used our pears to make a flan.
She recalled reading the recipe in a book from many, many years ago. We had to go looking, but we found the book eventually, just where we though that it ought to be. I skimmed past it initially, as the cover wasn’t like I remembered it.
Larger-than-life home cook, turned TV presenter, Ian Parmenter used to present a 5 minute cooking program as a fill-in on the ABC TV, possibly in the 80’s or 90’s? Called Consuming Passions Consuming Passionsand he later wrote a book called ‘Sheer Bottled Bliss’.
IMG_4773
Janine remembered his recipe for pear and almond up-side-down tart. It was very nice as I remembered it and just as nice this time round. Page 143, if you are interested.
IMG_4772it’s quite rich!
I tried my hand at prune and almond flan that I saw Rick Stein make on the Idiot Box one evening when he was in the Dordogne region of France. It look easy and I thought that I’d have a go at it. What could go wrong? Ididn’t have all the ingredients, but what the hell, give it a go.
Soak a couple of cups of your prunes in brandy. I didn’t have enough brandy, so I used half Cointreau. I think that It might even be an improvement!
Mix one of your beaten free-range eggs with the drained brandy. Then add in a cup of almond meal and half a cup of sugar. More or less.
IMG_4819  IMG_4821IMG_4823
Blind bake a short pastry base for 20 mins at 180 oC. then pour in the filling over the prunes and continue to bake for another 45 mins or more as required

I liked it so much, I made another one.

A Hand Made Efficient Home

As the days get shorter and the evenings cooler, we are lighting the wood fired kitchen stove most nights now. This old stove, that I have lovingly maintained and repaired for the past 40 or so years, cooks our food, heats our hot water, through its bronze firebox boiler, which is connected to our kitchen hot water system. It also heats the kitchen and us while we work, cook and eat.

IMG_4764

In the hottest couple of months of summer, we cook on the gas stove and rely on the solar hot water panels to heat the hot water. We have had to cover the solar panels with wire mesh, as we had a pine cone drop onto one of them shattering the tempered glass.

IMG_4796 IMG_4795

It may seem strange that we have our solar panels on the ground. I have a good reason. We have a full copper hot water system, with a copper hotter tank, a bronze boiler in the stove and copper solar panels, all connected in series, so that either or both heat sources can heat the tank depending on the weather and time of year. I used all silver soldered copper piping to connect the system, so there isn’t a separate heat exchanger needed in the system to eliminate electrolysis. A full copper system has no electrolysis issues. Eliminating the heat exchanger makes the system much more efficient. I designed the system so that the solar panels are on the ground, so that the hot water will rise up into the tank by natural thermo-siphon. No pump is need in the system to circulate the hot water to the tank. (as is necessary when the panels are on the roof.) This is another added efficiency and saving on energy. By designing systems like this and others in our hand-made home, we have managed to reduce our energy usage in our home to 1.7 kW/hrs per day for the house alone. If we add in charging the electric car and firing the electric kiln from the solar system, then our total usage rises up to 5.7 kW/hrs per day.

IMG_4797 (1)

When we add in our kiln and car, Janine and I still use only half of what a ‘normal’ single occupant household uses. Or just one-third of a ‘normal’ 2 person household. We are quite pleased with this outcome.

The Last of the Summers’ Tomatoes

We have reached the point where the tomatoes have lost most of their leaves. There are still loads of fruit on the vines. But the vines are looking pretty much dead. We pick all the remaining fruit for the last batch of concentrated tomato passata sauce. We have over twenty jars of the stuff from this years harvest, safely stored away in the pantry cupboard.

IMG_4622 IMG_4623

IMG_4692

IMG_4652

We pull out all the vines and compost them and remove the stakes. We pull out all the weeds. The beds are then ready for a load of compost and a new planting.

There are a basket of capsicums and chillies to harvest as well. I decide to roast them and pickle them to preserve them. They are sweated, peeled, de-seeded and then dressed with oil and vinegar. They will keep for a few weeks in the fridge treated like this.

We have only just finished the last batch of capsicums that I preserved in this way a week or so ago.

This is all standard autumn fare.

After the Hail Storm

A month ago we had a hail storm. Not too bad as hail storms go, but bad enough. There wasn’t a lot of rain with it, – a pity.

A few weeks later we had a lot of rain in an hour. Quite a storm all told. We found to our surprise that we had a number of leaks appear in our old school classroom. We had to find buckets for the drips on the carpet, the computer table and other various places around the house. Having drips of water dropping onto the carpet in what is our lounge room, really concentrates your attention.

I’m fixing a hole where the rain gets in and stops my mind from wandering!

We don’t usually have leaks like this, so I had to investigate. However, I needed to wait for it to stop raining, then to stop blowing, waiting for a day when there was no gusty wind. I once went up on the roof on a windy day and the ladder blew away, leaving me stranded up there until Janine came looking for me, replaced the ladder and let me come down. She must love me!

I finally found a day that wasn’t too windy, glarey or wet and slippery. I got up onto the top roof of the old classroom of the school. I found that the hail storm had pummelled the 130 year old corrugated galvanised iron roofing. Where there was an over-lap of the old sheets the iron had rusted to a very thin state because of the condensation in the over-lap, creating a few quite large holes.

A hundred years ago, corrugated iron roofing could only be manufactured in short lengths, as it was rotary folded across the sheets to make the corrugations. This meant that to cover a long-span, a number of shorter sheets needed to be used and this required overlapping to stop leaks. All old iron roofs suffer from this same problem of rusting out on the overlaps. We are lucky to have a roof that has survived for so long without too much trouble. We live in quite a relatively dry environment with about 500mm of rain each year.

I worked across the roof systematically siliconing every split, crack and thin rusty patch. The overlaps needed special attention. In one place I had to cut a small piece of rustic, but structurally very sound, old roofing iron into a small square. I glued this patch over the worst section, that was too big to close with just silicon alone.

The big issue turned out to be the ridge capping. This is 130 year old lead! I wanted to replace it 35 years ago, when I was much younger, able-bodied and building the extensions on to the Old School Classroom. I didn’t want any lead on my roof. Unfortunately I struck one massive problem that stopped me in my tracks. The old lead was about 600 mm wide and the old wooden roofing battons were well spaced accordingly. Modern galvanised ridge capping is only about 460mm wide. Not wide enough to reach the old battons. This meant removing all the old sheets of iron and screwing on new battons, then replacing the roofing, then screwing down the new narrow ridge capping. A massive job. Not one that I could complete easily in a day.

Being basically lazy, I decided that I had enough to do with building the new extensions onto the Old School classroom to make it into a house, so I left the old flashing up there. It was just easier to ignore it and hope for the best. The old lead capping has developed cracks and splits here and there along its length over the years. I siliconed these splits and cracks 30 years ago, and 20 years ago and then 10 years ago, Now the cracks are just too big and too long for silicon.

Now my lead flashing chickens are coming home to roost. I will need to re-roof the whole school roof eventually. I hope that I can make it last long enough, so that it isn’t my job to do. I couldn’t do it by myself now. I’d need to employ someone to help me these days.

My creative solution was to lift the old lead flashing and slide in new sections of shiny galvanised ridge capping in underneath the old lead. Then I screwed the old lead down over the new galvanised ridge capping, through into the old galvanised roofing. A cunning plan!

From a distance, no-one can tell that I did anything at all. It looks exactly as it did before I fixed it, and that’s the way I like it.

Bruised Butt Cheek Bones

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

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

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

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

IMG_4719

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

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

IMG_4693 IMG_4718

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

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

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

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

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

IMG_4661 IMG_4662

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