Nope, any vacuum contains less atoms, less atoms equal less conduction, less conduction equals greater heat retention for this process. watch?v=AFwG1RPbxlc The professional tube in this video has a vacuum created simply by the heat making glass process then from cooling. It boils water in plain sunlight.

This is silly. The vacuum created does nothing useful. You need 10,000 less air than atmospheric to do anything. This level is not really do-able by a DIYer. Do yourself a favor and just skip the vacuum step.

How do you heat the water exactly.?

stevenscowboys (November 30, 1999 at 12:00 am)

all this work to make hot water lol

Dan, if you play a blowtorch into a cooled glass vase just before you drop the vase down the contraction will suck the epoxy right up into the vase without any adjustments.

Another EXCELLENT video from D&D!!!! Hint: try sand-blasting the glass parts, where you want them to bond to the resin. This allows a much firmer bond! GREAT WORK!!!

Instead of using a vacuum pump (as many folk don't have access to one) then you can simply heat the vase with the hole drilled in the resin open and then put a stopper in it. As the air inside cools you will end up with a vacuum. You can almost create what ever vacuum you need using this method easily enough to implode your vase so go gentle to start with. A little bit of water inside acts as a vacuum lost indicator as water will remain vapour in a vacuum but condensate out if you lose it.
