You may have missed who I was replying to in the thread. The toplevel comment quotes Teflon's website talking about "cookware" in a generic sense, like heating up a pan with nothing in it is universally bad. That's bullshit. Obviously Teflon doesn't want to directly admit that it is specifically Teflon that, when heated, releases gases that will kill your birds dead. This happens at temperatures that would be no problem at all for stainless or carbon steel. That was my point. It's not the "overheating cookware" that's the problem, corporate weasel wording aside, it's specifically the Teflon that is the problem. I don't own or use any non-stick cookware.
