Multi-ply cookware with carbon steel cooking surface layer

A multi-ply cookware, comprising:

• a body comprising:
• a cooking surface layer formed from carbon steel having a carbon content of about 0.05% to about 2.0% carbon by weight, wherein the cooking surface layer has a thickness of about 0.1 mm to about 3.0 mm and forms an interior surface of the body;
• a thermal layer formed from aluminum and having a thickness of about 0.5 to about 5.0 mm, wherein the thermal layer is disposed below the cooking surface layer;
• and
• a protective layer formed from stainless steel and having a thickness of about 0.1 mm to about 3.0 mm, wherein the protective layer is disposed below the thermal layer and forms an exterior surface of the body,
• wherein the cooking surface layer, the thermal layer, and the protective layer are laminated together.

A method of manufacturing multi-ply cookware including a cooking surface layer and a thermal layer, the method comprising the steps of:

• providing a carbon steel sheet and a thermally conductive metal sheet, wherein the carbon steel sheet has a carbon content of about 0.05% to about 2.0% carbon by weight;
• laminating the carbon steel sheet and the thermally conductive metal sheet together to form a laminated sheet;
• forming the laminated sheet into a predetermined cookware shape, wherein the carbon steel sheet forms a cooking surface layer and the thermally conductive metal sheet forms a thermal layer disposed under the cooking surface layer;
• polishing the cooking surface layer;
• heating the cooking surface layer;
• and
• oiling the cooking surface layer.
