We have some cast iron that belonged to both of my grandmas, and some cast aluminum (Wagner) that belonged to one grandma. Also have some teflon, and several stainless steel pans. A few aluminum, the thinner kind. Each seems to have it's own special properties, but the cast iron, and the stainless are my favorites. I use the cast on the wood stove during the winter, and love cooking stuff that I can set in the dutch oven all day on the back of the stove. Stews, soups and chicken and dumplings. I don't worry about the teflon, as I don't use it for things that get extremely hot, just for reheating things. Don't use the thin aluminum often, but use the cast aluminum a lot, it's just like cast iron. My very favorite is the 16 inch cast iron chicken fryer, but it's so heavy that I can hardly lift it anymore. Had some of that pyrex stuff once, a whole set of the cranberry color, and it looked great cooked terrible.
