Slide 2: 

PMC® (Precious Metal Clay) is a clay consisting of tiny silver particles in an organic binder. It comes in a lump and canbe worked much like anyother clay.

Slide 3: 

While wet, the PMC is textured, shaped and cut…

. . . assembled . . .

…and dried.

Slide 6: 

When the PMC is dry, repairs and refinements are made and the greenware is filed smooth.

Slide 7: 

When it is completely dry, the PMC is fired at a temperature just under the melting point of the metal for a length of time to allow the metal particles to fuse together, also known as sintering.

Slide 8: 

After firing, the silver is fully sintered. The piece appears to have a white film on it. However, that is the silver particles “standing up.” Burnishing compacts the molecules and makes the piece shinier.

Slide 9: 

At this point, the piece is fine silver (99.9 percent silver) and can be filed, soldered, polished and worked like any other silver piece. This pair of earrings was given a patina with Liver of Sulphur.
