I make bowls from sheet copper on a lathe and then enamel over the top. The enamel is in grain form and gets applied over various parts of the form and fired for a few minutes in a small kiln at between 800-950°C. I work towards an interesting reaction between the various enamels, the copper and the heat of the kiln.
No two bowls are the same - each one is a unique combination of glass, metal and fire which is unrepeatable…
