Topic: Sealed smoothing station - Success!
Building on the many posts here, I'm thinking about building my own simple smoothing station, but one that has a sealed chamber so it is safer to use.
To start with, I'm thinking of something like a glass jar topped with some sort of expandable cap or bladder. The idea is that after placing about 1cc of acetone in the jar, you can place the jar in a bowl of hot water to boil the acetone. The expandable top (bladder?, balloon?) would take up the extra volume, yet keep everything contained until you put the jar in some cold water to condense the acetone again. Later on, some sort of magnet-driven fan could be added to stir the vapors inside.
Of course, the problem is finding a suitable bladder that would be resistant to acetone. I understand polypropylene is acetone resistant, and used for some expandable water bottles. For 1cc of acetone, I think I need something that can expand a least a liter in volume, since a mole of gas is 22l and a mole of water is about 18ml.
Any ideas? Is this a crazy?
