Jet powered snail chasing............
The first photo is of a piece of jet i bought in whitby which i wrapped in thin silver wire, to make a pendant. The next photo is of an un-polished piece of jet and one i polishd up on the grinder graduating through 6 different wheels (rough sanding, fine sanding, felt, calico, lambswool, and swan's down) to achieve a high shine!
The next to photos are of a piece of copper with a snail chased onto them. Chasing is a technique where the piece of metal is heated into a container of pitch and hammered from behind to achieve a 3d effect.
