Not so! The microwave is merely a "radio transmitter" which is supposed to
cause slightly-conductive molecules to "jiggle", the friction thereof causing
the heat. This doesn't work well with a concentrated FeCl solution simply
because the solution is HIGHLY conductive, so the first couple mm. of stuff,
hit by the RF first, SHIELD the rest from this energy. This DOES heat that
couple mm. mightily. So, the only way to heat FeCl properly in a microwave is
ten seconds at the time, and then STIR the container between each 10 sec.
nuking. This DOES mean opening the door and fiddling with it six to ten times
to heat up 100 ml. or so, but it is the ONLY way to prevent boiling of the
"edges" and poor heating of the "inside" of the container of stuff.
Do NOT do it with a copper board, etched or not, inside the microwave! This
will simply RUIN things! Just don't do it!
Been there; DONE that! Jan Rowland
