This is sounds like shoot from gun on sparrows.
The Magnetron is a powerful source to energy, but
cuts have a small area and are a bad receiver for it.
The paraffin much well misses microwaves, since
water is not. That is why water quickly boils from
beneath cut. Electric ventilator will better suit
for purpose fast drying.
We uses for drying slides conventional oven.
Please check Histonet archives (January 2006), that
this issue discussed.
What will say the vendors of microwave equipment?
