I have one of those smooth top, glass electric stoves which I dislike a great deal but Hubby, who sells appliances, insisted I had to have it when we moved into a new house. The result is that I can't use cast iron too successfully because every pan to to be completely flat on the bottom to make contact with the darn glass top. I my downstairs kitchen I have a gas stove which is what I definitely prefer. Upstairs I have to use those non-stick babies but I've bought all Caphalon over the past few years and they seem to be holding up well. I did learn that you simply can't use high heat with these pans, medium to start and then turning it down has saved the surface of the pan for the most part. It's nice having two complete kitchens, each with it's own features, but give me a gas stove everytime. SandyO CH #1146 of the moderate, gas-powered persuasion
