De Buyer Mineral B cookware is coated in an all-natural beeswax-based protective finish, providing a chemical-free alternative to standard non-stick processes. Fully recyclable, and with no added chemicals, this iron frypan can be effectively heated to very high temperatures (on all cooktops, including induction) and becomes darker, with more effective non-stick properties, as it is used again and again. We recommend seasoning this pan on first use to ensure the best performace.
