Each pan also features a pouring rim to prevent spills and a tight-fitting lid to lock in cooking aromas and flavors. The superior base stability of Industry5 cookware guarantees the bottom of the pan remains almost perfectly flat when heated, even to higher temperaturesEach piece of cookware features Demeyere's proprietary Silvinox finish—a unique system of electrochemical surface treatments that removes iron and impurities from the surface, the main causes of discoloration over time. The stainless steel exterior remains silvery white, even after many years of use. It also resists discoloration from fingerprints and heat, even when subjected to temperatures over 500°F.
