OK, if Teflon plastic, AKA polytetrafluoroethylene, is a "...is a
white solid at room temperature..." (much like many other polmerized
ethylenes!) as is said he

then what's that dark brownish coating on cookware made of? Not JUST
Teflon, I'm sure!! The above page says nothing about cookware coating,
or how they take a white plastic and make it into that brownish
coating. I'm curious!
I can totally understand Teflon's low low frictional coefficient, what
with only fluorine atoms on it's molecular outside. Fluorine is THE
most electronegative atom, I believe, resulting in extremely low Van
Der Waal forces which cause friction. So low in fact that Teflon is
the only substance a gecko lizard can't stick to! Someone tell Geico
insurance, quick! ;-)
LOL, great post. "degrades above 260°C (500°F)," hmmm.
Teflon frying pans must have some coloring agent because a white surface
would get dirty quickly. I have a Creuset pot (enamel inside & out)
with blue exterior and off-white interior, now stained halfway up
from cooking black beans.
While we're on frying pans -- I bought a new one at REI this year,
recommended by Backpacker magazine editors. Don't know if the coating
will last any longer than before, but it's a nice utensil. Mainly,
the folding handle shouldn't collapse when you've just got the chicken
cooked and onto the plate -- oops, into the sand.
