Did you giggle like a mad scientist?

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.
