Firing PMC silver clay is relatively goof-proof, but bronze and copper clay can send some artists over a cliff. There are more firing schedules and opinions regarding how to fire this medium than there are rehabs that have rejected Charlie Sheen! At first, I got semi-consistent results with the standard steel firing pan and charcoal, but with lots of early pieces, the binder did not completely burn out, and I broke many more pieces than I want to count. Then, I discovered Hadar Jacobson — the most amazing woman who keeps learning and experimenting with base metal clays, and willingly shares her knowledge in her own blog http://www.artinsilver.com/blog.html . I think every budding metal clay artist should buy her books and thoroughly read her blog and visit her website http://www.artinsilver.com . Since finding her site, I have exclusively used her fast fire bronze and copper clays. I also gave up the steel boxes and now use the fiber boxes she told us about on her blog. Below is a pic of a bronze focal piece I made a few weeks ago, and just recently fired. The first pic shows the piece fresh out of the kiln, and the second shows it after I brushed a section of it slightly so you can start to see the bronze peeking out. In the next few days, I will put it in a pickling solution in my little tiny hot pot to get rid of any leftover carbon residue and oxidation, then I will polish it with a flex shaft and add a patina to accent the textures. Then comes the difficult part – deciding how to turn it into a necklace — I’ll keep everybody up to date on that process as well. Don’t forget to check out my etsy site — I am adding pieces almost every day.
