Duh!
FeCl will vaporize and eat away at the copper and other metals in the
microwave oven circuitry. Some vaporization or "misting" will take place
even if the FeCl is heated to a temperature below its boiling point.
FeCl is corrosive and toxic.
Heating FeCl is not what I would call an "intelligent" tactic
unless you have specialized equipment designed to do so.
