This pan has gently curved sides for consistently perfect, easy to fold omelettes. Coated in an all-natural beeswax-based protective finish, providing a chemical-free alternative to standard non-stick processes, De Buyer Mineral B cookware is fully recyclable, and manufactured with no added chemicals. This iron frypan can be heated to very high temperatures (on all cooktops, including induction) and performs increasingly effectively the more you use it.
