I think that's how he's generating so much heat..

Doesn’t metal in the microwave produce a lot of arcing?

I melted stainless steel in a consumer grade microwave oven this
morning. The melting temp of stainless was a bench mark temp I am
trying to hit. A consumer grade infrared thermometer that is supposed
to go to 3000 F said it was 300F. Can’t use thermocouples due to the
high RF field inside. Still looking for a way to measure the temp of
the heating zone.
This is something I have been working on for a while. It really works
well. I have some silicon carbide foam that absorbs microwaves
embedded in some super high temp insulation. I got it so hot it
actually melted a hole in the foam and made a crater in the fire brick
it was setting on. No evidence of plasma, just pumping 1250 watts of
energy into a very well insulated item. I was astounded that it was
glowing through the insulation.
