Are you looking for a cheaper metal clay to practice with before working with silver clay? Here I share my initial experiments in shaping, finishing and firing pieces in Art Clay Copper. It's a lovely material that can be torch fired, with some caveats. This isn't an *easy* material to work with, but it is relatively low cost and therefore ideal for learning how to shape and join elements at the small jewelry scale.

This video doesn't touch on polishing or anything past the scope of initial shaping and firing experimentation.
