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™!
Composition: Metal powder (92.5% fine silver, 7.5% copper), water and organic binder
Color: Pickle white
• Firing temperature: 1,500°F (815°C)
• Melting point: 1,640°F (893°C)

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.
How To Finish PMC Designs
You have several options when it comes to finishing your PMC designs. Get a quick view of the various hand and machine finishing options.
HAND FINISHING: The simplest way to finish PMC® is to use your hands and some good, old-fashioned elbow grease.
• Polishing papers are rated in grits. The grit tells you how many particles per square inch the paper has; the lower the number, the more coarse the paper.
• Begin with a coarse paper (about 400-grit) and graduate to increasingly finer papers until you achieve the finish you want. Change the direction of the stroke when you change grits to see when the marks from the previous paper have been removed. Use adequate pressure so each grit paper can work effectively.
• A hand burnisher can be an alternative to using sanding paper. After firing, run the burnisher along the surface of the metal, moving in the same direction for each stroke, and overlapping strokes to avoid leaving drag marks.
MECHANICAL FINISHING: Use a mechanical polisher, such as a flex shaft, to create textures with less time and effort. They hold a variety of attachments, offering a range of application options. Most polishers accept a range of accessories.
• A foot-pedal control is an important accessory; it keeps your hands free to work and allow you to control the motor speed as you work, changing speeds as needed for each piece.
• A flex shaft reduces hand fatigue and strain; it allows you to hang the motor from a stand and work with a smaller, lighter handpiece.
• Mounted motors give you the convenience of hands-free operation and accept larger attachments; they are ideal for large or flat pieces and for higher production needs.

Explanation of Terms
The first three clays are 100% silver. PMC PRO contains 90% silver with the balance
being a proprietary alloy. Sterling contains 92.5% silver, balance typically copper.
The nonmetal content refers to water and binder.
In all clays, shrinkage occurs equally along the x-, y-, and z axes unless the clay is constrained or restricted. The degree of shrinkage is related to the amount of binder.
Some clays offer options that balance a lower temperature against a longer soaking time. See other charts for the relative merits of the other schedules. Always fire at the highest temperature and longest time possible.
This refers to the degree a sample can be stretched before it breaks. Relevance: A ring with a higher number can be sized by stretching.
Related to elongation, this measurement shows how much force is needed to break a sample. A higher number means the piece will be harder to break.
This is a measure of how much force is needed to bend a sample. The higher the number, the more rigid the piece will be. Relevance: A ring with a high number will not bend out of shape when worn.
Surface Hardness (Vickers)
This refers to a test that measures what happens when a point of specific size is pressed into a sample. Relevance: A high number here means the surface is hard; textures and details will not wear away quickly.
We can think of this as a measure of how tightly packed the crystals are. Generally the tighter the structure, the tougher the metal. In objects of a given size, a denser material will weigh more.
