Since no one else has answered...I was using my double boiler to boil off the everclear i used to make the cco. So should I be getting my everclear mixture to that high of a temp when I'm evaporating the alcohol??
No, you don't want to use that high of a temperature to evaporate alcohol, stick with water in the lower half of a double boiler.
Make sure to do this in a well ventilated area, preferably in a covered area outside.
No open flame or possible source of electrical spark nearby.
Stay upwind or use a fan to blow fumes away from you.
Vapor recovery, if possible, would be ideal.
If I missed any of the warnings, someone please complete the list.
