What is PMC Silver ?

Precious Metal Clay® (PMC) represents a dramatic development in working with precious metals.  PMC Silver consists of microscopic particles of silver suspended in an organic binder to create a pliable material with a consistency similar to that of modeling clay.  PMC can be worked with fingers and simple tools to create a vast range of forms and surfaces that are unobtainable or laborious using traditional techniques.  When it is heated to a high temperature, the binder burns away and the metal particles fuse to form solid metal that can be sanded, soldered, colored and polished like conventional materials.

Precious Metal Clay is a patented material developed in the early 1990s by Mitsubishi Materials Corporation of Japan. The principal ingredient in PMC is tiny metal particles only 20 microns in diameter.  It takes as many as 25 of these particles to make up a single grain of table salt.  The rest of the material consists of water and an organic (naturally occurring) binder. After firing, both the water and binder are completely removed, so PMC may be hallmarked and will assay as .999 pure. Dried-out PMC or unwanted fired objects can be refined just like conventional precious metal.

The firing process leaves a metal that is less dense than conventional sheet or wire. This means that a piece of jewelry made of PMC is lighter than the same piece made by fabrication or casting.
