iso alcohol?
fuck no.. keep that shit far far away from the stove... or anything with a flame....
Put it outside, start heating some water, put your container of oil into a larger container of hot water... Hot water baths are the best way to go when you want to evaporate solvents without a flame...
Trust me on this, the shit will flash.... i have done it and seen it happen... a large container filled with boiling and flaming solvent is not something you want in the kitchen...
microwave is also a bad idea... Alcohol will evaporate and he vapors will probably fill the microwave until concentrations are right, then it flashes and blows the door off the microwave and a fireball ensues...
