Several knowledgeable people have performed extensive firing tests of natural and manmade gemstones at typical metal clay firing schedules. These are extremely helpful in determining how risky it is to fire a particular type of stone in place.

Not every stone produced identical test results in the different firing tests, and the tests also vary in terms of whether the stones were tested loose or embedded in metal clay, the types of clay in which the stones were embedded, and the firing schedules tested, so I usually consult several of the charts before deciding whether or not I think a particular stone is a good risk for firing in place in the type of clay and at the firing schedule I plan to use.

Gemstones in Metal Clay
This fabulous guide by Mardel Rein of Cool Tools shows which natural and synthetic gemstones can be fired successfully in metal clay, by what methods (kiln and/or butane torch), and at what temperatures. It's formatted as a PDF file for easy printing, and you'll want to keep a copy in your work area for frequent reference

It includes tests at the longer/hotter BRONZclay and COPPRclay firing schedules, and is the gemstone testing chart I turn to most often. It reflects the combine gemstone firing test results of Mardel Rein and Kevin Whitmore of Rio Grande.MORE;Silver Jewelry
