I did some large and small test blocks with ART INSTITUTE GLITTER ULTRAFINE TRANSPARENT GLITTER in a the Castin’ Craft polyester resin. I wanted to make sure it would not sink to the bottom of the resin. Within a few minutes, the piece was grey and cloudy and all of the glitter appeared to have melted? I had been taking the temperature of the resin via a laser temperature gun and I never saw the surface temperature exceed 90 degrees, so I am inclined to think it was a chemical reaction. Can polyester glitter be used in a different type of crystal clear resin? Would I have better luck with a polyurethane resin?

Hi William,

How strange! I’ve never had this happen with glitter.

Is it possible for you to pour less resin at once? That would generate a little less heat which might be what the glitter needs. Polyurethanes get hot too, so I don’t know that will fix the problem.

Have you tried different brands of glitters?
