I'm not sure where to post this question, and couldn't find any pertinent information elsewhere.
I've read and seen videos that say when you cure resin in a pressure pot the "bubbles shrink". What exactly does that mean? Is the air inside a bubble being compressed into a microscopic area, or is the air being squeezed out of the resin, with only minor residual air remaining inside?
If you apply, for example, 40 psi to the liquid resin, and that pressure shrinks a bubble - is the hardened resin permanently applying 40 psi of pressure to that bubble even after you take the resin out of the pot? Is the microscopic bubble a tiny bomb of 40 psi waiting to expand? Because if it's not, then that means most of the air from the original bubble escaped the resin. The pressure inside the bubble can't be neutral once cured if most of the air did not escape.
Does anybody know what's actually happening?
