Re^2: Bubbles- steel epoxy dies., Bubbles- Steel epoxy dies

Hi,
AFter pouring, try putting the whole thing in the freezer. This works for RTV molds (Room Temperature Vulcanizing). I don't have a vacuum, so this was suggested to me, and it worked! the low temp. slows down the cure rate, giving the bubbles time to flost to the top and burst.

Warning: make sure to seal the mold well. I had a real mess in my freezer from one mold!
