Query: The non-stick material is PTFE

From Wikipedia "Polytetrafluoroethylene (PTFE) is a fluoropolymer discovered by Roy J. Plunkett (1910-1994) of DuPont in 1938. It was introduced as a commercial product in 1946 and is generally known to the public by DuPont's brand name Teflon."So even though they advertise their products as not having Teflon, it is made with the exact same materials as those called Teflon, they just don't use the Teflon name. So those who want to avoid the offgasing of non stick products may want to think twice about this one as well.Update: Offgassing aside, we did buy this pan a little more than a year ago and it just got thrown away. We only use the non-metal utensils and take very good care of our cookware, but this pan performed like every other non-stick pan we've tried. It works great for a while and then craps out. It is the last teflon-like pan we will buy and we are looking at better alternatives.
