Ceramic itself is safe. Ultimately for a coating, the safety depends on what's underneath if/when it wears through.

- ok_dad 4y agoIs it really ceramic or something they call "ceramic" that has other additives like a metamaterial?
- kragen 4y agoIn materials science "ceramic" means basically any inorganic, nonmetallic solid: https://en.wikipedia.org/wiki/Template:Fundamental_aspects_of_materials_science https://en.wikipedia.org/wiki/Template:Fundamental_aspects_o.... This includes perfectly safe materials like alumina, mullite, and silicon nitride, as well as things you definitely do not want in your food like lead oxide, lead zirconate titanate, barium titanate, uranium oxide, and beryllia. So it is not accurate to say, "Ceramic itself is safe". (I have no idea what is used in the surfaces of "ceramic" pans but it is unlikely to be any of the substances I listed above; they all have high surface energy.)
