Over the last couple of years I've been developing techniques for working in sheet copper and copper clay. Copper Clay is a PMT clay that is 90% copper and the rest a binder. You carve and model the clay then fire it to burn the binders off leaving pure copper. I finish this with traditional chemical patina's used on sheet copper. The other copper work is old fashioned embossing / repose', also finished with traditional patina's and sealed with art waxes to preserve the finish for years to come.
