I wouldn't use a hair-dryer it has a glowing filament inside it that may ignite the fumes .Honestly I haven't tried it yet but I've heard of people using hair dryers you just heating it up and up to evaporate the alcohol I mean the super lowest setting there is take you about two or three hours but like I said keep watching it take it off the burner and move the pan around I see how it's evaporating it doesn't take long really easy to do only hard part is is waiting for 2 weeks while it's sitting in the jar
Induction electric cooktop is the best
