Would it be any different than putting a chunk of steel in the oven? Why does metal spark and flash when bombarded by microwave energy? Why do grapes give off poisonous flourescent gas when bombarded by microwave energy? Thanks for answering, but don't be a dork please. Check this out::

The magnetic properties of a metallic object in a microwave are irrelevant: it is only its conductivity that counts. A metal object in a microwave concentrates the energy, exceeding the breakdown voltage of air and causing sparks. Grapes in a microwave may burst and emit steam, but the vapor is not toxic.

The hot gas is "plasma" which is another matter state, just one we don't see very often, solid, liquid, gas, then plasma. The plasma I suspect is from water vapor, and once it cools should be safe I think, but perhaps there is some high temp reaction that changes it? I don't think so though. The earlier answer about the concentration of the electrical energy by metal objects is correct though as I understand it the object must have points or ridges larger than the wavelenght of the microwaves. I haven't tried it but belive that is should be safe to put a well pollished metal sphere in and it wouldn't spark....
