I haven't done much cooking in my glass pots (Don't remember if these were
really glass, but they were either clear amber, or clear brownish purple). I
only got them when my acupuncturist had me cooking up a mixture of Chinese
herbs. He said only a glass pan would do, if I remember correctly. I was
directed to simmer the herbs for many hours, and therefore wouldn't have
expected
anything to burn, but I remember I just couldn't get the residue off the
pots. Of course scouring on glass with a steel scrubbing pad isn't much fun.
I
have never used the pots again, but seem to remember I never did get the
caked-on or burned-on residue off.
Of course, I'm not talking about the Corningware-type ceramic pans, or those
appearing to be clear glass, used to bake in the oven, or in the microwave.
These come clean easily by scrubbing with a stainless steel scrub pad, or
even the nylon back of a sponge (after soaking). I was just talking about
those pots used on the stove top over a flame.
The handles on these glass pots also got very hot and were hard to handle
(similar to cast iron handles).
Hope this helps,
Jill
