Isn't that the problem? From what I am googling right now, the maximum tempreature of my stove is absolutely above the threshold where it stops being chemically inert. If we were talking about some usage that didn't involve heating, then I guess maybe I'd hear out a usage for it, but even then, not sure the benefits are worth having something that can't degrade and yet can potentially get ingested by my body.

PTFE is very inert, but that doesn't mean that I want to eat more of it than I have to. And as a practical matter: Once it begins flaking off, more tends to follow. I don't know if that's because of oxidation of the aluminum, or what, but it sure seems to behave that way.

I mean, I'm not too awful worried about it compared to my adventures in 3D printing (with its crusty PTFE Bowden tubes).

But I very deliberately have just exactly one Teflon-coated pan in my house, and it only gets used for exactly one purpose: Making scrambled eggs with a rubber spatula. (I like my eggs scrambled sometimes, and I'm not pro-enough to make it work with cast iron or stainless cookware.)
