Thank you. I had heard microwave was discovered because it melted a chocolate bar in some guys pocket. I knew that you can use them to ionize the gas in florescent tubes and freak out the Boatswains Mates or so I'd heard. I was in the US Navy Reserve for a spell.

I didn't know things like dishware would heat up on its own. We got our first microwave 40 years ago as mentioned. The warning was always never to run the oven without something moist to absorb the energy. So I've never put just a plate in.
