Bubbles?

Anyway to get the air bubbles out?
I don’t think they are butane, I vac purged for a few hours at 115
I think it’s good otherwise, my first time.

At 115F, you should be molten, and at -29.5" Hg/10,000 microns, there shouldn't be enough air for a bubble. How are you measuring temperature of the puddle?

Just air temp inside the vac chamber

You might try bumping up your temperature until you achieve full melt. The bubbles won't stick around if they have an easy way out.
