So am I correct in assuming that a vacuum chamber is used to "stabilize" blanks and a pressure pot is used to "cast" blanks?
I have some blanks that may need to be stabilized. So I need a seal tight chamber and a vacuum pump and Cactus Juice. Is Cactus Juice the best medium? Where is the best place to get it?
Off to YouTube to watch more videos on the subject.

Yup! The idea is to have a clear view of the blanks under vacuum so you can control the amount of air flow to control the bubbles. So that the juice doesn't get sucked up into the pump. Cast under pressure with a pot. Doesn't have to viewed during the process.
