Abstract

A cookware vessel has an upper portion of the surrounding sidewall that is insulated by a cavity to maintain the temperature of the food cooked therein until and during the service of food from the vessel. A highly conductive metal layer, such as a copper layer, extends upward along the inner wall surface adjacent to the inner vessel to spread heat from the bottom of the vessel up the inner sidewall. The copper layer is bonded to the both the inner and outer vessel at the bottom of the vessel and portions of the outer sidewall that would otherwise be overheated by a burner flame and then discolor. In a preferred embodiment, the brazing compound comprises silver to further improve thermal conduction. The copper layer may also extend to the bottom exterior of the vessel to provide an improved means from measuring the temperature of the contents during cooking.
