After a second round of casting polyurethane cabochons for eyes, a mass of tiny bubbles still manage to ruin the final product.
Can someone please tell me if there's any way to get rid of these annoying bubbles.
I've already tried mixing slowly, heating up the bottes before casting and using a low temp heat gun to pop the bubbles.
(The last method probably didn't work because it's not an epoxy resin).
Even using a tooth pick to pop the bubbles isn't possible since the bubbles are so small, but there's so many of them that you can see them very easily.
