RESINS: castable for jewelry

Bonjour,
Is there some body with experience/tries on casting resins for jewelry?
The actual FORMLAB resins have a high point of calcination, hier than traditional jewel casters-between 350°C and 500°C…
Thanks for your eventual response.

I think this guy wanted to discuss that. You might get some good info from his thread.

But I don’t think he is ever coming back.
