Abstract:
Cookware, and an induction cooking system including the cookware, include a container, a base layer, and a susceptor layer. The container and the base layer are non-magnetic at room temperature, while the susceptor layer is magnetic at room temperature and has a Curie temperature at which the susceptor layer becomes non-magnetic. During heating of a material within the container, the base layer functions as a passive heat exchange to transfer heat across the susceptor layer. Further, during the heating, the base layer conducts an electric current when the susceptor layer approaches a leveling temperature and/or the Curie temperature of the susceptor layer, thereby decreasing an amount of heat produced and resulting in a more even heating of the material.
