If you're in a hurry use a heating pad and a fan blowing on the evap dish. I've never done the microwave thing but it gives me the heebie jeebies thinking of my hash getting nuked. cheers,
Not so sure about it destroying resin molecules, the heat it generates could denature some stuff, but u dont want an arc to occur, which can happen, and the micro goes boom. Heating pad + fan as mentioned works great. Double boiler on an electric stove with ample ventilation too.
