I make models and figures from Super Sculpey and sometimes I put gemstones in them...
Amethysts go yellow once they come in to contact with heat, will they still retain there original colour at 275 degree F (130 degree C) as this is what heat is required to cure Sculpey,
Thanks

why not set the stones in after you have baked the sculpture.?

Amethysts are heat treated to get the better color ...very touchy and precise work...reheating them without knowing whats been previously done to them is a crap shoot...

This site says 400-600C for color change
