I use microwave oven to heat gelatin size all the time and have not
had a single problem. But like anything else but plain water, if you
use microwave you should heat halfway first, stir it, and heat it
again just to the desired temperature. Trying to do it one shot will
make hot spots and this is not desirable with gelatin size.
