ABSTRACT:
A coating containing flakes made of a thermally conductive material is disposed on the inner surface of the bottom of a cooking vessel. A first portion of the flakes is oriented in the plane of the inner surface and a second portion of the flakes is oriented in the thickness direction of the coating to form a heat conductive pattern. The flakes include flakes having a longest dimension that is greater than the thickness of the coating, thus improving heat transfer from the bottom of the cooking vessel to the upper surface of the coating. The heat conductive pattern includes a plurality of segments that extend outwardly from a center region of the inner surface toward an outer peripheral region. The outwardly extending segments improve heat transfer from the center region to the outer peripheral region, especially when the cooking vessel is heated by a heating element having a diameter smaller than the diameter of the cooking vessel bottom. The outwardly extending segments also improve the uniformity of the heat distribution about the upper surface of the coating, thus ensuring even heating of the cooking vessel's contents.
