I have a set of 3 Bra Premiere non-stick frying pans that I’ve used for a while. The coating on them says “Teflon Innovations without PFOA”. Recently I’ve noticed that on the most used pan, the 26cm one, the Teflon coating has started to peel off.

I know that Teflon coatings can release harmful fumes and chemicals if overheated, but what about if the coating is physically peeling? Is it still safe to cook with them? Or should I stop using especially the 26cm one? I don’t want to keep exposing my family to anything dangerous unknowingly. Any advice if these types of pans are still safe to cook with if the nonstick surface is peeling would be appreciated!

    The barrier to acids comes from oxidizing the surface, which anodizing does. But pores do not exist in bare aluminum, and hard anodize actually has the biggest pores! There is technically a sealer on the surface, but sticking it in hot water can sometimes release it, depending on what sealer was used. Here’s an article with more info: https://www.lightmetalage.com/news/industry-news/surface-finishing/introduction-to-anodizing-aluminum/

      That’s for general anodizing, not hard anodizing for cookware. They aren’t going to use the same process for a chair that will never see water versus a pan designed to be immersed in water. Anodized cookware is fine to use with acids.

        Nope. It’s exactly the same process - it’s just Type III not type II.

        The sealer is what makes it non porous. That sealer is usually teflon that wears off.

          It’s the exact same process, except that it isn’t. Hard anodized aluminum is not teflon.

        Can you give me an example? Calphalon for instance have “hard-anodized nonstick” but they’re still teflon. Anodizing is actually how teflon is usually made - the anodizing makes a porous surface that the teflon can stick to. So you’right that the sealer is different, it’s just teflon.

            Correct, hard anodized does not equal Teflon. But point me to a link selling just a hard anodized pan. If you search “hard anodized cookware” the top links are all hard anodized + teflon (“nonstick”). Tfal, Calphalon, Cuisinart…

                They all seem to be ceramic-coated. So. When will you admit that hard-anodized is porus, requires a coating, and the coating can still be teflon? “Hard Anodized” is a useless keyword.

                  I’ll admit that you simply want to do everything possible to prove me wrong on a single point on a post that has nothing to do with that you’re arguing about. Seriously, I’m done trying to convince you of anything. Have a nice day…

                    And I’ll guess I’ll stop arguing with soneone who can’t count, Bonehead.
