Sterling? Sterling! This Precious Metal Clay™ comes out of the kiln as a solid sterling silver piece! Because it is sterling, this clay will have 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.
Work, roll, cut, shape and fire versatile PMC® like any ordinary clay. After firing, your design comes out of your oven as a sterling silver object. Create jewelry, beads, components--anything you can do with clay, you can do with PMC Sterling™!

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.
• 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.
How To Create 960 Sterling PMC
Any time you need a high-silver formula of PMC® clay, you can create a clay that comes out of the kiln as sterling silver AND lets you skip the two-step, carbon-embedded firing process! These steps show you how to quickly and easily combine two PMC varieties to produce a sterling clay that is 96% pure silver.
Measure or weigh out equal parts of PMC3™ and PMC Sterling™. The simplest way to do this is to use one 25g-package of each clay.
Fold the two lumps of clay together, kneading them gently until you achieve a uniform grayish color. No water, oil or release agent is needed.
Your high-silver PMC is now ready to use. Form, shape and texture the clay as you would any PMC to create your design. and allow it to dry completely.
Fire the clay piece(s) at full ramp to 1,500°F and hold for 1 hour to ensure complete sintering of the metal.
