Abstract
A cookware article with a textured surface and a method for producing the same. The method comprising performing a first forging step to create a three-dimensional body of the article of cookware from a sheet material having first and second opposing major surfaces, wherein the three-dimensional body comprises a concave form in which the first surface comprises an internal surface and the second surface comprises an external surface, performing a second forging step on the three-dimensional body to impart a surface texture over the internal surface, applying a non-stick coating to the textured internal surface.

A method for producing an article of cookware with a textured internal surface comprising:
- performing a first forging step to create a three-dimensional body of the article of cookware from a sheet material having first and second opposing major surfaces, wherein the three-dimensional body comprises a concave form in which the first surface comprises an internal surface and the second surface comprises an external surface;
- performing a second forging step on the three-dimensional body to impart a surface texture over the internal surface;
- roughening the internal surface texture to receive a surface coating;
- applying a non-stick coating to the internal surface with a thickness so that the surface texture is present after coating.
A cookware article comprising:
- a three-dimensional body of concave form having internal and external surfaces, the body comprising an underlying metallic material and a non-stick coating layer over the internal surface;
- a surface texture pressed into the underlying metallic material of the body, the surface texture comprising a pattern of discrete raised portions spaced by valleys therebetween, said pattern extending over the internal surface;
- the non-stick coating layer overlying the textured surface, the non-stick coating layer having a thickness such that the pattern of the surface texture is present in the surface coating.
