The Prestige multi-ply line has a solid foundation built from five layers comprised of a 18/0 magnetic stainless steel base layer, pure and alloy aluminum, finished with an 18/10 stainless steel layer with a diamond nonstick coating, making this the most prestigious line in stainless steel cookware. The patented nonstick coating provides brilliant cooking performance and enhanced food-release properties. The bonded layers allow the heat to be evenly distributed and retained around the pan, removing the possibility of hot spots. In saucepans, casseroles and stock pots, the layers also allow for a constant and even temperature in the walls, thus reducing energy loss and reducing cooking times. This cookware is induction compatible and can be used on all cooktops and easily be transferable to the oven, with lids, up to 500°F (260°C). Most pieces include a heat-tempered, sturdy glass lid. All of the handles are ergonomically designed to stay cool on the stovetop. The saute pans, woks and saucepans have a helper handle for additional ease.
