Does anyone know what the coating of 'granite' cookware is made from? On Wikipedia there's nothing, and I've noticed it seems to have replaced non-stick teflon pans in supermarkets. It's usually marketed as 'eco-friendly' and 'PFOA free'. I stayed in a couple of airbnbs that had this type of pans, and they seemed to work just like any other non-stick pan. The base seems to be a mixture of aluminium and steel (as it works on induction). https://www.amazon.com/Carote-Stone-Derived-Non-Stick-Switzerland-Including/dp/B0732NXYNS https://www.amazon.com/Carote-Stone-Derived-Non-Stick-Switze...
