After learning more about the dangers of hot Teflon, I tossed all I had, especially since I manage to scratch them a lot. Moved over to Corning Ware and Stainless Steel, even have a marvelous Stainless Steel electric frying pan, which I use most often in summer, far less heat that way. Gave my too heavy old cast iron to son, who had drooled over it for years (so did his wife).
