Abstract
Multi-ply cookware having inner and outer plies of aluminum or stainless steel encasing an intermediate ply of a graphite material. The graphite material, which has thermally anisotropic properties, is oriented so that its thermal conductivity is higher in the plane parallel to the surface of the cookware than in the direction perpendicular to the surface. Accordingly, when the cookware is placed over a localized heat source, the intermediate graphite ply effectively conducts and distributes the heat provided by the burner throughout the plane parallel to the surface of the cookware before the heat propagates in the direction perpendicular to the surface of the cookware, thus minimizing hot spots on the inner surface.
