Precious Metal Clay (PMC) is an exciting new product developed by the Mitsubishi Corporation. The finest microscopic particles of silver or gold are suspended in an organic binder which gives it the consistency of modeling clay. PMC can be formed into a vast array of shapes and textures using a wide variety of tools as well as using your bare hands. When fired and held at the right temperature, the H2O and binder sinter and burn-off as the metal fuses together leaving your creation in 99.9% pure silver or gold with the original shape, textures and details intact (slight shrinkage occurs). The result is a solid piece of either Fine Silver or Gold. Once removed from the kiln, it can be finished with a variety of techniques including tumbling, soldering to other pieces, scratch brushing, burnishing, etc. It can also take on various patinas using a variety of solutions like liver of sulfer or raku. PMC is certified to be completely non-toxic in both its pre-firing clay and post-firing solid metal forms. For more information on this product, I encourage you to visit the PMC Guild!
