lol I keep doing this! argh, ok Iso is an alright way to do it.... except you end up burning alot of the good stuff off when you have to get rid of the iso, I've let my iso oil sit outside in the sun until it all evaporated off but honestly that took like 2 or 3 weeks...Cooking off the iso on an element is so retarted, your more likely to burn yourself...
as long as you take precautions like, no flames in the area, I use a leather glove to hold my turkey baster, cause it's dam cold.... wouldn't ever do this inside...... if you use a small dish like I said then one a bit bigger with some hot water, it doesn't matter what the temp is outside you'll have smokable oil in like 10 min.
