Techniques for designing and creating energy efficient cookware are provided. In accordance with the techniques cookware can include a cookware base having a cooking surface and heating surface. The heating surface can have a pattern of fins forming heat exchange channels. The channel fins can improve energy transfer while providing even distribution throughout the cooking surface. Methods of making the energy efficient cookware are provided. Methods of direct forming channel fins by impact bonding and forging are disclosed.


1. A method of making a piece of energy efficient cookware comprising: providing a piece of cookware having a wall and a base, the base including a heating surface and a cooking surface; andimpact bonding a piece of metal on the base using a patterned mould, simultaneously extruding said metal to create fins with a height of larger than 6 mm in a pattern complementary to the pattern of the mould operable to transfer thermal energy from a heat source to the cooking surface. 2. The method of claim 1, wherein the cookware comprises stainless steel. 3. The m...
