Before we got a u-wave oven, I had always heard that one should NEVER NEVER
NEVER put any metal in it.  Ours came with a metal rack, and metal interior
(with little ceramic pieces to hold the rack away from the sides), and
instructions regarding metal in u-wave ovens.  Metals reflect microwaves
(kind of like they do with radar), so you want to make sure that there is
plenty of food to absorb the microwaves in a place where they'll hit.  Also
you shouldn't allow metal to touch metal.  We have a ceramic plate that fits
on the bottom of the oven, and frequently use a sheet of Al foil to heat up
nachos on.  Don't put metal over the top of the food or it will bounce the
waves back to the magnetron, burning it out (so sez the booklet).
