Work, roll, cut, shape and fire versatile PMC® like any ordinary clay. After firing, designs made with PMC Sterling™ clay come out of your oven as a sterling silver object. Create jewelry, beads, components—anything you can do with clay, you can do with PMC! PMC Sterling™ clay has more than twice the strength of original fine silver PMC, ideal for more delicate designs and for pieces that just have to have the added strength. Because of the copper content in this formula, firing is a two-step process; step one is an open-shelf firing and step two requires a firing pan with activated carbon media.
Composition: Metal powder (92.5% fine silver, 7.5% copper), water and organic binder

• 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. • Because of the copper content in this formula, firing is a two-step process; step one is an open-shelf firing and step two requires a firing pan with activated carbon media. • 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. • IMPORTANT: Sterling silver is an alloy containing metals that react with chemicals found in air and produce tarnish; high moisture levels, exposure to sunlight and contaminants such as salt water increase this reaction. Take steps to protect your sterling findings by keeping them in airtight packages, use tarnish-resistant products (such as tarnish tabs or strips) that absorb harmful chemicals, and store sterling findings in a cool, dry place. Most tarnish is easily removed by polishing with a mild abrasive or soaking in an anti-tarnish solution.
