The invention discloses a manufacturing method for a soup pot with partial concave-convex patterns on an outer surface thereof. The method comprises: preparing a plane blank for forming a pot body; screen-printing a layer of ink with preset patterns on a surface of the blank of the pot body; screen-printing a layer of ink with preset patterns on a bottom surface of the blank of the pot body; etching at positions where no patterns occurs on the surface of the blank of the pot body; stretching the blank of the pot body to form a soup pot, and flashing the edge of the pot body; and spraying a nonstick pan coating on the blank of the pot body, and polishing with abrasive paper at positions where the convex patterns occur and where no pattern occurs.

Provided is a method of producing a cooking vessel, including the following steps: forming a blank from a sheet of stainless steel; drawing of the blank to form a cap comprising an interior surface and an exterior surface, the interior surface comprising a flat base area surrounded by a side wall; hot stamping of a diffuser base onto the exterior surface of the cap; engraving of a grid pattern over at least one portion of the base area of the interior surface of the cap to form a network of ribs having top surfaces that extend above the valleys and side surfaces that are distinct from the bottom surfaces of the valleys, said side surfaces of the ribs connecting the top surfaces of the ribs to the bottom surfaces of the valleys, the side surfaces of the ribs forming ramps connecting the top surfaces of the ribs to the bottom surfaces of the valley; sanding of at least the engraved base area of the interior surface of the cap, to create roughness; applying a non-stick coating on at least the sanded, engraved base area; and brushing and/or polishing of at least the sanded, engraved and coated base area to reveal the stainless steel on the top surfaces of the ribs.

Cookware has both as copper and a stainless steel mesh embedded in the exterior facing surface of the bottom of the base. The embedding process work hardens the bottom of an aluminum cooper vessel. A ferromagnetic stainless steel is embedded into the cooper mesh, forming portion of the exterior bottom surface of the cookware to render the cookware compatible with induction cooking heat sources.

Cookware surfaces of metal, such as aluminum, may include a nonstick coating and embedded hard metal mesh. The mesh protects the nonstick coating between interior regions within the mesh from being cut or abraded by knives and other tools.

A process for manufacturing a frying pan includes the steps of material selecting, cutting, machining and forming, welding, grinding, sanding, cleaning, baking, preparing of a ceramic paint, spraying of a ceramic paint, curing, cooling and the like.
