I used to cook frozen pizza in the microwave in college. The packaging
specifically said not to, but I figured after 30 minutes anything that
might have killed me would be dead. So if you microwave anything for
long enough, you'll get a result.

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.
