I have a vacuum furnace I can set up. I want to cast glass into a mold. The unit is rated for 1100c. If the glass will slump I'm guessing without air it may conform to a mold. The question is, Is this possible at all at 1100c?
What would be the lowest temperature without air/bubble worry? I need to make some repairs so I can probably raise it to 1200. I'm hoping the vacuum takes all the bubble issues away allowing lower temperatures.
(Also posted to casting, but this is probably the right place).

Re: Casting in vacuum furnace
at 1000 c you have glass in basically a liquid form, glass blowers have their glass at around that temperature and it's the consistency of honey.
So yes that is plenty hot.
Respectfully though if you are not aware of basic temps I doubt this is something you should undertake.
