Was just hit by anti-teflon-itis with my cookware, so thought I'd de-teflon-ize my stir crazy which gets to at least 483F during a roast. I used various pieces of sandpaper and sanding blocks. I should have cafiza'ed it before sanding. Took an hour or 2 of sand/vacuum/rest...
You were going to get a pic of this later today...
teflon at room temp is inert. afaik
teflon at high temps outgasses a potentially poisonous gas. Opinions vary as to a safe high temp (600F? 500? ...)(cf google)(enjoy!) EDIT: PTFE: Polytetrafluoroethylene . fluoro
I don't think the problem is a serious one in teflon coated thick anodized aluminum pots, but more in the infinitude of cheap teflon coated pan-ware where the substrate is not thick enough to evenly distribute the heat and extremities, away from liquid, can reach elevated temps.
Nonetheless I decided to retire all my teflon stuff (like 5 pieces) and work on playing with ss/alum/ss sandwich stuff, or enameled cast iron - basically whatever I can find inexpensively at Marshals or fleabay. EDIT also thick copper (not revereware)/alum/ss, or thick copper/ss . ss by itself does a very poor job of transmitting heat.
{the latest trigger for this I found humorous - was eyeing pans at Macys (teflon coated anodized aluminum), and a customer came over and commented that she liked teflon but understood that once you scratched it it was cancerous. I indicated that I thought that was not true, but I later took it to simply be one more tap on the shoulder to look for an alternative.}
You're welcome. I'm going to work on a custom made ss insert for the stircrazy. Not too long ago one person posted a roaster where the entire motor assembly was gutted and transferred to another plate - I forget if it was ss.
