ABSTRACT:
A dual wall cookware article is formed by bonding a ferromagnetic metal base plate to an assembly that includes an inner vessel, a thermally conductive layer and an outer vessel frame. The outer vessel frame has upright walls that surround a bottom having plural perforations. The bonding process causes the softer thermally conductive material to flow through the perforations and bond ferromagnetic metal base to the outer vessel frame and the inner vessel.
