Induction cooking is starting to take hold. It has many advantages: fast heating, precision control, and safety. A couple of those may sound familiar. Copper has long had the advantages of precision control and efficient heating. However, copper is not magnetic and is not compatible with induction cooktops. Falk CopperCore is the solution! Five years in the making, it is the best induction-ready copper cookware available. CopperCore is made up of a 0.4 mm layer of ferretic stainless over a 1.9 mm thick core of pure copper and our standard 0.2 mm stainless steel interior. The cooking vessels are the same shape and size as the Classic and Signature lines. The stainless steel handles are the same as our Signature line.
