Does too much broiling wear out a broiling pan? Does too much baking wear out a cookie sheet?

Bakeware fatigue?

I have never seen or heard of such a thing.

I don’t know about the hot cold thing, but over time if there is a coating on the pan or sheet the coating might wear out or flake off. If there is no coating you might start getting stains on the cookie sheet or baking pan.

I usually bake cookies on a Silpat on top of really cheap metal baking sheets.

I bake a lot of my casserole type foods in glass baking pans. Sometimes at the end I brown the top with a quick broil, and my 25 year old glass pans are like new.

My metal baking sheets that I sometimes broil on (usually veggies) are stained, but they function just as well as when they were new.

Most broiler pans that are porcelain coated are safe to over 1000* F and stainless higher than that.!

I’ve cookie sheets with a “varnish” from cooking on them (easier to remove cookies).

Had the same pans for donkey’s years. Never a problem.

Depends on what they are made of.

Yes, at the molecular level, there might be some loss, but you lose more molecules every time you wash it with an abrasive sponge.

But even so, it will outlive you.

Porcelain-coated steel – no problem. User-friendly silicone rubber inserts in the pan – not so good.
