> Ceramics and plastics are the worst (this includes any non-sticking coatings), because, unlike for metals and glasses, their chemical composition is usually kept secret by their manufactures, so you never know what they may leach.

Again, when you refer to ceramics, are you referring to the tons of ceramic coated cookware that is now immensely popular as a replacement for Teflon? Is this stuff just as bad? https://www.goodhousekeeping.com/cooking-tools/a26078798/bes...
