PMC3 consists of microscopic particles of 99.99% silver, mixed with an organic binder and water enabling you to create as you would with any other clay. Once dry the clay is fired either by a butane torch or in a kiln and you left with a solid piece of hallmarkable silver.
A very strong clay. Due its lower range of kiln temperatures a wider range of stones can be fired with PMC3. Glass, ceramics, sterling and other metals can be fired safely with this clay. Especially good for rings and pieces that require extra strength. Shrinkage rate 10-12%. Can be torch fired on kiln temperature range 1650°F to 1110°F
