This Precious Metal Clay comes out of your kiln as a sterling silver object after just a one-step, open-air firing process (no need to embed in carbon!), and the clay is as easy to work with as original fine-silver PMC
OneFire Sterling PMCcontains a higher percentage of fine silver (95%) with just a touch of copper (5%) to give it the strength of sterling with the bright whiteness of silver.
This clay is ideal for more delicate designs and for pieces that just have to have the added strength.
In addition, you can solder on your fired pieces with any grade of silver solder, and they are suitable for enameling, keum-boo, stone-setting, and even plating, if desired.

please note: Every variety of PMC is sold by the metal weight, not the weight that includes the water and binders that burn off during firing. You get every gram of precious metal you pay for from PMC. PMC has a strong adverse reaction to contact with aluminum. Do not use aluminum tools or allow your PMC to come into contact with any aluminum object.
