I just noticed your pigment bottles say “polyester/polyurethane” on them. Are they also suitable for your clear cast epoxy?

Thanks Warren...in which case, part two of question :-).

I mixed some glasscast for the first time on Sunday...fresh tin;, never opened, only a month or two since ordered.

I made up 60g, so 40g resin, 20g hardener. Few drops or your red translucent pigment. Stirred it well by hand, cast it into a silicone mould made two days before.

How hard should the product be after two days? It still has a distinct “taffyish” feel...it’s only a 100x100 square by 4mm deep.

Thanks!
