Cookware features Hydrolon - PFOA free nonstick which results in fewer greenhouse gases. Hydrolon is water based. We have replaced PFOA solvents with water. When the non-stick is applied to the pan water solvent evaporates rather than emitting PFOA into the air. Our cookware uses manufacturing techniques that do not include the use of PFOA toxins. Made of heavy duty gauge carbon steel. Riveted steel handles offer a firm and stable grip. Suitable for all heat sources, including induction.
