In one incarnation I planned to raku fire the plaque using a simple white crackle glaze for the background and either glazing the tree green or leaving it carbon black. But believe it or not, despite all the raku firings in the past couple of years, there simply wasn’t room or time between raku orders and stock replacement for me to pop the plaque into the kiln! Unfortunately the poor thing wasn’t a priority in all the flame and sawdust, so it never happened.
My next plan was to reduction fire the piece using a gas kiln. I thought about using a white or clear glaze with wax resist on the tree to highlight the design, creating a speckled effect under the glaze and a dark toasted brown on the unglazed areas. But then, would you believe it, the gas kiln broke! In fact the gas kiln was out of action for many months last year for various reasons. It all began with a misfire caused by a power cut (the controls and safety switch are electric) which plunged the pottery studio into darkness, wheels spinning slowly to a stop. Let’s just say this event ‘coincided’ with the setting-up of the stage and cabling for last year’s Isle of Wight Festival...(!) Anyway, yet again, poor little plaque didn’t get glazed.
Then a couple of months ago I found the forgotten little plaque wrapped in tissue in a drawer; bisque fired but looking quite forlorn. So I made a decision: stick to something simple! I used a mixture of oxides (iron, cobalt and manganese oxides in equal parts) and brushed this into the tree design, wiping back with a damp sponge. Then I took a wide flat brush loaded with plain white glaze and simply ‘swiped’ over the top. Done! Fired in an electric kiln in oxidation and finished at last! You can see the different stages of making – from painting to finished plaque – in the photos at the top of the post. What the photos don’t show is the complicated, logistically chaotic and random stuff that sometimes goes on in the background when you try to made decisions about glazing!
It took me a few evenings to read through and gave me quite a lot of head scratching. But once I got past the scientific/robotic language and reassured myself no one was actually going to test me on this (!) I started to get more of an understanding of things. There was even a chapter dedicated to oxidation and reduction featuring pottery kilns as an example, which made me feel justified in making the effort.
Once I got through it, my next point of call was my copy of ‘Minerals, Rocks and Fossils’ published by Philip’s. I’ve had this on my shelf for ten years now and whenever I’ve tried to read it I couldn’t quite get my head around it. It’s full of chemical formulas, geological language and pictures of pretty rocks in crystal form. This time though it all made sense! In fact it read like a natural progression from the Chemistry book and now the poor thing is covered in post-it notes and scribblings about minerals with particular colour properties.
Getting this background information and putting a context to the chemical side of ceramics has cleared-up a lot of vague fuzziness in my head. I feel much more confidant about what the ingredients in a glaze actually are, instead of just taking the names written in a glaze recipe book for granted. I’ve still got more reading to do though before I can start doing some experiments of my own: but it just goes to show that doing a bit of homework really does pay off!
Here are some links to books I was using:
I mentioned in a previous post that I’d bought some new brushes (click here). I’ve been using these to create large, flat marks on some of my pots. The photo above is an example of this on a new vase. This pot has been hand-thrown in stoneware clay and brushed with a white slip beneath a clear glaze. Then iron oxide was brushed on using the smallest of the wide brushes and allowed to drip naturally. The pot was then reduction fired in a gas kiln. As you can see, the iron oxide has created a beautiful deep metallic red/brown mark. (This pot is for sale in my Folksy Shop!)
I also have some Chinese-style potter’s brushes made in bamboo – which you can see above. These are perfect for decorating with oxides or slips. This style of brushwork is something new to me however, so instead of wasting any expensive oxides or fired pots I thought I’d do some practise first! So I used some watered-down acrylic paint on absorbent handmade paper to try out some shapes. Of course paint on paper doesn’t flow in quite the same way as oxides on clay: for one thing oxides absorb instantly onto glazes and the flow of the brush is different too. But it really helped to experiment and get an idea of the shapes and marks that are possible. I also practised some brush marks onto the side of a finished vase – just to get the hang of decorating around a three-dimensional shape.
Overall it was fun to do and a really interesting exercise. You can always learn so much more from doing instead of just looking at pictures! At the moment though it’s still too early to tell whether this is something I will fully pursue or not in my own work. It may end up being something I tried a few times, but wasn’t for me: who knows!
In the past couple of weeks I’ve had some time to relax away from making pots and painting, and reflect on just how busy 2010 was for me! Pretty much rushed off my feet for most of the year, or so it seemed! And although it’s been really good and I’ve learnt lots of things and had lots of positive feedback from people, in the last few months I’ve been feeling as though things were running away from me a bit: getting swept along in a rush. And so it seems a perfect time – especially since we’re firmly into 2011 already – for me to re-evaluate what I’m doing.
Hence the photos of this teapot. A long time ago, back in March 2010, I made this ‘unexpected teapot’. It was unexpected mostly because it was hand-built (which I don’t really do, being mostly a potter) and also because it was unplanned and fairly spontaneous. And ever since then I’ve been meaning to blog about it when it came out of the kiln. It came out months ago but I never had the time to mention it. So here it is at last: slightly wobbly around the edges for being hand-built, but charmingly so I hope! It’s been reduction fired in a gas kiln and glazed using a clear glaze that allows the natural iron in the clay to show through as a lovely speckled effect. It’s only small – it holds just enough for a single cup of refreshing green tea - but it’s very cute I hope you’ll agree, and for once I decided to keep it all for myself (which is something I rarely do these days!)
But the point I’m trying to make is that this teapot was an experiment - and recently I’ve been feeling that experiments and creativity have been a bit sidelined in all the noisy demands and logistics of running a small art/craft business. It’s probably inevitable at times that the ‘business’ side of things takes over, but I’ve decided that this year I’m going to be focusing much more on developing what I make by getting back to the creative side of things. Get the balance back. At least that’s the plan.
Oh yes, and I really must do some painting too…
Over the past couple of days I’ve been sorting through a selection of small accessories that came out of the last glaze kiln. These included buttons, brooches, pendants, rings and miscellaneous ‘blanks’. All of these little pieces require some finishing touches. First I usually smooth them all using sandpaper to soften the edges and make sure they don’t snag on clothing or feel rough against the skin. After sanding I add the fittings like brooch backs and ring findings (I use Araldite as a ceramic fixative and the fittings come from my local bead shop). I also thread the pendants onto lovely new suede thongs and individually attach each button onto card in singles or matching pairs to keep them together. All in all it takes a day or two to go through all the pieces - choosing which items go best with which fitting (and also trying not to glue my fingers together). But it’s all worth it in the end I think – especially now I have a new selection of jewellery and buttons (with brand new glazes!) for my next show.
Talking of which…our next show is coming up very soon. My sister Sue and I will be sharing a stall together again (as Osmosis) at this year's Isle of Wight Garlic Festival next weekend (14th and 15th of August). It’s our second year at the festival. Last year was very good for us and we had lots of interest in our work, so we hope it will be successful again this year. We’ll be exhibiting in the Arts and Crafts marquee on site with lots of other local artists and craft makers - and there’ll be plenty of other attractions over the two day event including live music and lovely food stalls with garlic to eat of course! So if you’re in the area, please do drop by: here’s a link to their official site.
And I just wanted to thank Helen again for featuring my bowl on her lovely blog last week: here’s a screenshot, and here’s a link to her blog too. Thanks!
