## Questions & Answers

**Q: Are these cz "kiln ready", can they be used in PMC (precious metal clay) jewelry?**
A: Yes they cane be used in PMC. I have used them and they fired best at about 1550 for about an hour. However remember that the emerald green and blues turn color when fired at that temperature.

**Q: Can these be fired in silver clay with a torch?**
A: I have no idea, but it's a very interesting question. It looks like the white tolerate much higher temps than the colored cz. Any idea what temp you need to successfully fire the pmc? I would love to hear if you have success with it.
