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!
Anodized aluminum is porous, that’s how the dye stays attached. Also aluminum is not recommended for use with acidic foods. I would personally avoid it.
Aluminum is porous. Hard anodized aluminum is not. That’s the whole point of anodizing the aluminum, so that it creates a barrier that stops it from reacting with acids.
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.
Hard anodized aluminum is sealed with something, often teflon.
If there’s teflon, then it’s advertised as non-stick. Just because it’s sealed doesn’t mean it’s always 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.

Hard anodized aluminum is not 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…
Search for “hard anodized PTFE free”…
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.
