PMC is a fun and simple way to create your very own fine silver jewelry, small sculpture and of course BEADS! Just mold like normal clay, allow to air dry and fire in a kiln. The binder burns away, leaving you with a beautiful piece of fine silver jewelry. Use PMC molding mats or create your own intricate patterns, the natural shrinkage from firing results in patterns appearing even more intricate than they originally were. Original PMC needs a high firing temperature and has a 28% shrinkage and is the most affordable of the clays. PMC+ has a 12-15% shrinkage. PMC3 also has a 12-15% shrinkage and can be fired using just a torch, but is the most dense. All the clays can be re-hydrated before firing so waste is of little concern. Be sure to pick up a Book or DVD for some great ideas and instruction.
