| Precious Metal Clay or PMC was developed in the early 1990s Metal clay is a clay-like medium used to make jewellery, beads and small sculpture. It consists of very small particles of metals (such as silver, gold, platinum, or copper) mixed with an organic binder and water. Alloys such as bronze or steel are also available. Metal clay can be shaped just like any soft clay, by hand or using moulds. After drying, it can be fired in a variety of ways including in a kiln, with a handheld gas torch, or on a gas stove. The binder burns away, leaving the pure, sintered metal. Shrinkage of between 8% and 30% occurs (depending on the product used), but this is exploited by artisans to produce very fine detail. Silver metal clay results in objects containing 0.999 pure silver - aka fine silver, which is ideal for enameling. Although gold metal clay is much more expensive to use, the color and richness is phenomenal. It can be used to make stunning solid gold objects or used sparingly to make beautiful accents on silver pieces. Lump metal clay is sold in sealed packets to keep it moist and workable. The silver versions are also available as a softer paste in a pre-filled syringe which can be used to produce extruded forms, in small jars of slip and as paper-like sheets, from which most of the moisture has been removed. There are two popular brands of silver metal clay, Precious Metal Clay (PMC) and Art Clay Silver (ACS). From Wikipedia, the free encyclopedia |
