    But it would be nice if we had a safe way of waterproofing materials.

      At this point, I don't really intrinsically trust any new chemicals for mass deployment. We have a real bad history over the last 100 years of inventing a new thing, deploying it worldwide, then only discovering the nasty unintended consequences 50 years later (or sooner, but results hidden by said company).

      If they make it into a cooking pan, it damn well better be tested the way actual users do: Scraping with a metal fork, burning the crap out of stuff on it and then quenching the scalding hot pan in water. And testing for any and all deterioration. None of this "follow instructions precisely" crap...it needs to be foolproof or we might as well just keep using PFAS.

      So far, nothing really seems to hold a candle to a good old cast-iron pan once you factor in environmental risk.

        It really does seem like our ability to make new things greatly exceeds our ability to test those things and foresee their side effects.
