ABSTRACT:
A cooking vessel is formed with one or more annular rings rising above a laminate structure that exposes at least one more thermally conductive material of a contrasting color. The raised rings reveal the nature of the thermally conductive material, yet protect it from scratches and abrasion during use, such as when the cooking vessel is resting on a stove top.
