Designed for use with any portable or built-in induction cooktop, this handy 8-inch disk acts as a heat converter, making it possible to cook with any type of cookware including aluminum, glass, copper, porcelain, and non-magnetic stainless steel. Simply place the disk between any induction cooktop and the cookware of choice--anything from small fry pans and saucepans to larger griddles and stockpots--for safe, efficient cooking. The unit's durable stainless-steel construction evenly distributes heat, while its stay-cool handle ensures a secure, comfortable grip. The induction interface disk measures 8 by 15 by 1/2 inches.
