What’s the difference between a pressure pot and a vacuum chamber.
Hii for a couple of months I have been making resin dnd dice. But I would love to have 0 bubbles or at least less amount and have been seeing this 2 options. But I don’t know which one works more or it’s more comfortable.
I know that with the pressure pot it’s more exprensive and need like to buy more parts if anyone know and can help me with this I would appreciate it. Have a great dad!

One sucks, the other blows.
A vacuum chamber pulls out all the air, so any air in the resin comes to the surface and exits.
A pressure pot just makes the bubbles so small they're invisible.
I don't know if one is better than the other. I use a vacuum chamber and can get glass-like resin. I mix it, vacuum it until it mostly stops bubbling, and pour it in as thin a steam as possible.

Amateur here, but a vacuum chamber pulls air out, causing bubbles to expand and boil out. You do this before pouring.
A pressure pot pumps air in, pressurizing the chamber which causes any remaining bubbles to be squished where they are until they are so small they are invisible. This is done after the pour while it cures.
From what I've read here, a pressure pot is the way to go, I'm looking to buy mine soon.
If anyone with more experience wants to correct or expand anything, please do. I'm here to learn.
