Are these cz "kiln ready", can they be used in PMC (precious metal clay) jewelry?

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.

Can these be fired in silver clay with a torch?

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.
