Back in Seventies I made enamel jewellery I actually made a living from it, as every one knows the fashion just died along with CB radios etc. Well all this talk in the other thread about the white enamel failure and speaking with my friend in QLD has inspired me, I've just bought a used enamel kiln, these days I think I will aim for more sophistication and use Silver and Gold instead of just Copper as was the go back then.
