Shouldn’t the vacuum insulate the glass from the heat of the burning filament?

    And those are usually made out of some metal, that’ll do pretty good reflecting radiation heat transfer

        You ever seen those vacuum ovens too? Kinda doing the opposite, only letting radiation in, but from just solar radiation I’ve heard in sub zero temps they can get to a constant 500 F. Wonder what one would be capable of with some one way mirror type refraction to keep all that shit in
