A cooking utensil for use with an induction range has a first layer including a magnetic metal which is capable of being inductively heated, and a second layer which includes a ply of aluminum and a ply of copper, this second layer being in intimate thermally conducting contact with the first layer and being located interiorly of the utensil with respect to the first layer. The first layer may have a ply of carbon steel located between two plies of stainless steel. A disclosed utensil has its bottom and side walls formed of a first layer with an inner ply of inductively heatable magnetic material, and an outer ply of copper or stainless steel; a second layer with a thermally conductive aluminum or copper ply which lies in direct contact with the magnetic material; and, a stainless steel layer at the interior of the utensil. A stainless steel ring encloses the perimetral edge of the utensil wall. To deter corrosion of the carbon steel at the edge of the utensil, the circumferential edge of the utensil has a stainless steel ring which encloses a metal which, in the galvanic series, is sacrificial with respect to the carbon steel.

Induction cooking utensils

A metal sheet is deformed to produce a blank which has one side which is smooth and another side which is ornamented with a pattern of raised and/or depressed areas. The blank is deformed to produce a cooking vessel which has the ornamented side located on its exterior surface.
