There, inside the mw oven, was an ALUMINUM FOIL COVERED dish.I thought "I've fried this thing, for sure!" But I took the foil off and
felt the food and it was hot. I ran it for another 20-30 seconds, just to
see if it worked, and it did.I don't understand how it could have NOT caused sparking and a terrible
fire, because I once tried to heat up a jar of peanut butter (to get the
last of it out of the jar), and there was a sliver of the foil from the
top
of the jar left, and it caused all sorts of sparking and smoke, it was
really actually very scary.
The mass of foil on a low plane like that is not a problem. You can use
foil to block the MW rays from hitting certain parts of the food so as not
to overcook them.
OTOH, the thin foil ring around the top of a jar acts like an antenna.
Spoon sticking out of a cup, vertical metal will cause a spark to jump
across, but a pan is OK. The only reason aluminum pans are not use is
because the heating will only take place from the top, not both sides,
taking more time to heat.
