Precious Metal Clay
Have you heard of PMC, Precious Metal Clay?  
It is a very neat material to work with.
The PMC I use is .999 fine silver and comes in several
different forms, such as; in a syringe, paste, paper, or clay.  
Each form has benefits, however all work must be done
quickly before it dries out. Reconstitution is possible.
Precious Metal Clay, PMC, is an exciting material developed and patented in the 1990s by
Mitsubishi Materials of Japan. Microscopic particles of silver are mixed with a moist binder
to create a material that has the feel and working properties of modeling clay. Using simple
tools, objects are easily given shape, texture, and character. After air-drying, the objects are
heated to temperatures approaching the melting point of the metal, where the particles fuse
together to make a dense, fully metallic object. Fired PMC work can be polished, soldered,
enameled, and enjoyed like any other silver item. PMC is available in three different versions
of silver and in a 22k gold alloy.
