Healthy Legend Professional Ceramic Coating cookware features clean, elegant lines for a most unique cookware design. It comes with the best ceramic non-stick coating from the German Weiburger Greblon. Scanpan Professional is made from a core of solid squeeze-cast aluminum, forged into shape with 250 tons of pressure. The optimum thickness of the pan base prevents warping and keeps the pan base perfectly flat, especially important when used with glass top or ceramic ranges. The patented ceramic nonstick surface from Germany is best answer to the widely known health and cancer hazard from using all traditional PFOA based non-stick surface. Almost all the non-stick cookware in department stores now are traditional PFOA based coating including the very expensive ones. If you choose to use only stainless steel cookware, you need to add a lot more oil and they are hard to clean. Healthy Legend professional cookware is safe to use with metal utensils because the coating is much harder than other non-stick coating such as Teflon. However, you should still use the non-stick cooking utensils on the save side. The only way you can damage the coating is to hit it hard with a metal utensil. It cannot scratch off easily but it can chip off like any ceramic. Why is Healthy Legend cookware Environmentally Friendly? Healthy Legend Cookware has always been PFOA and PTFE free. With their German Weiburger Greblon ceramic coating, there is no PFOA used at any stage of the entire process, resulting in a "clean and green" nonstick surface from a smooth ceramic finish. The performance of the Healthy Legend ceramic cooking surface is not different in any way from the performance of PFOA based surface. The only difference is such ceramic coating color or gray. I had replaced all my traditional non-stick coating cookwares with the Healthy Legend cookware. The included high quality glass lid is break resistance glass allow food monitoring without lid removal.
