I haven't really had "disasters." I did used to do scrambled eggs in the microwave, but I got weary of the chiseling afterwards, and it turns out that we like the eggs better with sauteed vegetables in them anyway.
I bought a nice cup from the Space Center in Cape Canaveral. Used it to heat tea or coffee in the microwave. Apparently, I wasn't connecting with the fact that the cup was largely metal. Went to take it out, noticed that the shiny cup had turned to dark dull gray, and I about scorched my hand as soon as I touched it. I still have the cup, but it's not nearly so pretty, and it never gets used. We use cups that we can stick in the microwave for a quick reheat.
