Copper Clay is so fun to work with and itís less expensive than silver clay. Copper Clay can be pinched, rolled, sculpted and manipulated just like ordinary modeling clay. The binder materials burn away completely during the kiln-firing or torch-firing process, leaving a solid copper object with a density over 95% that of cast copper. Copper clay is available in big 30-gram, 100-gram and 200-gram blocks and is very affordable. COPPRclay allows the jewelry artist to experiment, and can even be enameled and worked like sheet copper.
