The invention is includes a cooking surface having an aluminum or aluminum alloy substrate that is hard anodized which is not sealed during an anodizing process and is then coated with seasoning oil such that the seasoning oil first penetrates the open anodized pores and is adhered therein. The base polymerization oil is held within the microscopic pores in the substrate and cured in situ. The process bonds the oil to the surface creating a non-stick cooking surface. In instances where worn spots develop between the pores on the surface, the surface can be refreshed with a simple recoating linking the pores that retain the original layer, maintaining the non-stick surface. The method provides for the process of curing the oil and polymerizing the oil within the pores before any sealing occurs on the aluminum/aluminum oxide substrate.
A method of forming an adhered layer of polymerized seasoning oil on a non-stick anodized aluminum or aluminum alloy pan such that the polymerized oil is retained within the porous substrate of the pan, comprising the steps of:
The method claim of 1, wherein the pores in said open porous, unsealed pan surface remain substantially open through the step of applying the polymerizing seasoning oil and permit penetration of the polymerizing seasoning oil into the pores of the open porous, unsealed surface and initially retain the polymerizing oil within the pores by surface adhesion.
The method step of 1, wherein the step of anodizing an aluminum pan surface to produce an open porous, unsealed anodized pan surface further comprises anodizing the pan so as to provide a pore size sufficient to permit the infiltration of the polymerizing seasoning oil but allow for surface adhesive forces to retain the oil within the pores and thereby securely bond the polymerizing seasoning oil into the pores and retain the oil in the pores in the heating step to polymerize the oil in the pores as a base layer for the nonstick cooking surface.
