Which non-stick pan coatings are safe coatings?

Ceramic coating, graphene coating, medical stone coating and other coatings are quite safe. The non-stick pan coated with graphene is expensive and low in cost performance. The non-stick pan coated with medical stone has poor wear resistance, and the coating will be scratched if you are not careful. Comparatively speaking, ceramic coating is the most suitable for home use, especially Shentian nano-ceramic micro-pressure cooker, which adopts 0 fluorine coating, has excellent non-stick and thermal conductivity, can better maintain the original flavor of ingredients, save energy and time, and is easy to clean.
