Is it possible to completely purge ethanol off at low heat ... like 100, and with the add of a strong vac (got an edwards rv12). I've made my resin sheet micro thin by flattening it, and streching while it's in a taffy state. I've had a hard vac for over 15 hrs and still flexible. Will it ever shatter, or do I need higher heat? The piece is about 8 or 9 grams ... maybe I should try to purge 2-3 gram increments. Any help? BTW still seeing small bubble, not many, but there's a few ... which leads me to believe there's still ethanol in it.
