These pictures are from Richard Salley's Repoussé Without Pitch class. We didn't use pitch and I have no idea what pitch is and why you would use it anyway -- I guess Ignorance is Bliss for me. Repoussé means you shape the metal from the backside to make raised areas on the front side. We then could assemble the shaped pieces into pendants but most of us just kept working on our small pieces to get the technique down. The bright colors came from the torching of the copper and most of us were using the tools we had made in his previous toolmaking class.
The picture above is one of my pieces and so is this one right below, which Susan calls "Man with Creative Atomic Fart".
