What is Precious Metal Clay (PMC)?
Precious Metal Clay is an incredible material invented by the Japanese. The principal ingredient in PMC is microscopic particles of silver only 20 microns in diameter. As a point of reference, it would take as many as 25 of these particles to make up a single grain of table salt. The rest of the material consists of water & an organic binder. The clay can be molded & shaped into many different designs. Then it is fired in a kiln where both the water & binder burn away & the metal particles fuse to form solid Silver 99.9% pure (for comparison, Sterling is only 92.5% pure). I often use a variety of different types of fused glass (including Dichroic and Murano glasses) within my designs to make spectacular & unique jewelry.
