    Has there been any evidence to point out that PFTE is not inert?

    This article seems to be about the production of PFTE, which is well-known to be quite harmful, but the end product is as far as I know not unsafe to use.

        That article basically confirms my understanding of the safety implications of PTFE. Don’t overheat, and discard once flaking, but ingesting flakes is unlikely to be harmful.

        I’ve started favouring other types of cookware as well - my personal favourite is enameled cast iron - but I’m really not keen on using neither cast iron nor carbon steel. I feel like proponents downplay the increased maintenance that comes with that type of cookware.

        I do have one ceramic non-stick pan that is pretty good, but once it goes bad I’m probably going to try to find an enameled cast iron replacement for it.

          I love my cast iron specifically because it requires extremely little maintenance. The only inconveniece compared to stainless steel pans is that after I wash it, I have to dry it by hand or toss it on the stove until it dries to avoid rust.

          Other than that, I never manually season it (just cooking with it does that for me), I only use metal or wood utensils (I scrape foods vigorously, especially smashburgers, and the seasoning is totally fine).

          IMO if the seasoning isn’t good enough to handle my abuse, then it isn’t good enough to be on the pan.

          Been using 'em for years and they still look brand new. Also what they say about seasoning being non-stick is true. It’s crazy how I can grill chicken breast without any oil and it barely sticks at all. The sear you can get on a cast iron due to heat retention is also second to none.

          My problem with enameled cast iron is that once the enamel cracks or chips, that cookware is essentially garbage (similar to PTFE cookware in that eay). The enamel is essentially glass, and you don’t want to eat microshards of glass. You can’t put it through the kind of abuse that I like to put my cookware through.

          Enameled cookware is great for acidic sauces, though, as one comment mentioned above. My recommendation for enameled cookware is to only use wood utensils. I just cook tomato sauce in my regular cast iron, though, and so long as I clean it right after, I never have any issues, but if I want to cook a tomato sauce for hours, I’ll use a stainless steel pot.

          Stainless steel is just as durable, but doesn’t have the seasoning that makes it non-stick, and it doesn’t hold anywhere near as much heat as a cast iron (unless you get the really expensive ones with a fuckton of copper in it), meaning it’s harder to get a sear for foods that need it. Fantastic for basically anything that you don’t need a sear on, like sauces, pasta, etc. A good rule is the heavier the pan, the more heat it holds.

            IMO if the seasoning isn’t good enough to handle my abuse, then it isn’t good enough to be on the pan.

            This is true, and something that I discovered myself recently. I tried babying one of my cast iron pans for while, seasoning with flaxseed oil, avoiding metal utensils, and only cleaning with a damp sponge or paper towel. I built up a seasoning quickly, but it was incredibly brittle, and actually began flaking off into my food. I haven’t used that pan since, haven’t gotten around to stripping and reasoning it.

            Since then I’ve had the same mindset as you to great success: if this layer of seasoning can’t handle my abuse now, then it’s not fit to be the foundation for the next layer of seasoning. I almost exclusively use metal utensils now, clean with a copper scratch pad, and ditched the hard-but-brittle flax seed oil for whatever I happened to be cooking with. Don’t get me wrong, I’m not aggressive with the pan, I let the weight of the utensil or pad do all the work, but I’m not letting weak seasoning get seasoned over. If it’s weak enough that the copper pad takes it off, then it wasn’t a good seasoning anyway.

              Hell, I scrape hard, scrub hard with a stainless steel scrubber and dish soap, stack cast irons for storage, etc.

              It’s a massive hunk of iron. I treat it as such.

          The problem with ceramic non-stick is it apparently has an even shorter lifetime than ptfe. Sure it’s an improvement on what you’re putting into your body, but every other type of cookware is also much more durable.

          I expect my current cast iron and stainless steel to be the last cookware I have to buy

        What’s “too hot” in this case?

        Edit: the news link actually works and doesn’t assail me with popups. Here’s the salient part:

        When these pans are heated above 260 degrees Celsius, their PTFE coating can begin to deteriorate. But the coating does not significantly degrade until temperatures reach 349C, Professor Jones says.

        "So, unless your oil starts smoking, you’re not getting to that temperature and even then, you need continued exposure to see any effects, which are usually minor in humans.

        “And that’s assuming you weren’t using an extractor fan or other form of ventilation while cooking.”

        I always use a ventilator fan, so this is apparently not a problem for me beyond the non-stick coating wearing to the point where shit sticks and I have to buy a new one.

      Previous formulations were also claimed to be inert and non-toxic, but were later found not to be. Current ptfe seems to be safe so far but at this point I’m really cynical about safety of these chemicals, industry willingness to inflict them on us and ineffectiveness of governments safety regulations. They’re forever chemicals. Even if they are safe, they will be in the environment, in ever increasing doses, forever. They are accumulating in you, your food, everything you ingest, forever. That doesn’t seem prudent.

      What are you going to do if a toxic pattern emerges, but you’ve already incorporated ptfe into your body? even if the the end product is safe, manufacturing chemicals are not: do you accept your part in these toxic forever chemicals?

      There’s not much an individual can do, but I can replace non-stick with other materials as they grow older. I have cast iron, stainless, glass, or ceramic as appropriate, that we know lasts longer and will not have a problem.
