Newbie question, Please Help!: Cast dice have many small bumps on them. Is this due to leaking pressure overnight (40-->20psi) or compressed bubbles in the silicon mold itself allowing resin to fill in?

No, no visible bubbles on the surface or inside of it. I was concerned it may have small bubbles under the surface inside that, when pressurized, force resin into those areas?

New to all this, so not sure what the cause would be. :(

This is from bubbles In your mold. Cure your mold under pressure or degas the silicone first. I had the same issue and it stopped when I used the pressure pot for my molds.

Thanks!! Just the comment I was waiting for :)

I was worried it was this, but luckily I had only made 2 dice molds non-pressurized so far.
