An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include 15 to 50 wt % of phosphorus pentoxide (P.sub.2O.sub.5); 5 to 20 wt % of one or more of lithium superoxide (Li.sub.2O), sodium oxide (Na.sub.2O), or potassium oxide (K.sub.2O); 1 to 5 wt % of one or more of sodium fluoride (NaF), calcium fluoride (CaF.sub.2), or aluminum fluoride (AlF.sub.3); 1 to 35 wt % of one or more of magnesium oxide (MgO), barium oxide (BaO), or calcium oxide (CaO); and 5 to 30 wt % of one or more of manganese dioxide (MnO.sub.2), molybdenum trioxide (MoO.sub.3), bismuth oxide (Bi.sub.2O.sub.3), or nickel oxide (NiO). The enamel composition may be cleaned without being putting it into water.

A method for preparing no-mess fudge is provided. The process for preparing no-mess fudge may include a firming container and a stand-up container. The stand-up container retains a plurality of pre-measured fudge ingredients. The stand-up container may be sleeve providing a seal on one end and a flat base on the other. In preparation of making fudge, a user may cut vents and/or tear notches through the seal. The user may then heat the stand-up container for a sufficient time to properly prepare the plurality of ingredients. The user may then knead the stand-up container for a sufficient time to properly mix the plurality of ingredients. The user may then urge the plurality of ingredients out of the stand-up container and into the firming container so that the plurality of ingredients may set to fudge of a desired hardness.

A composition for coating stainless steel includes sodium silicate, lithium silicate, sodium tetraborate, and a solvent as the remainder so that a contaminant on the surface of stainless steel is easily removed and yellowing of the stainless steel can be prevented. A cooking appliance includes the stainless steel surface coated with the composition.

Heat resistant and/or nonstick polymer materials and composites, and cookware including a food support surface comprising an integrated or attached cooking surface formed of the materials and composites. The cookware includes a laminate material with structural rigidity, wherein the laminate material includes a flexible substrate impregnated with the heat resistant polymer material and/or coated with a nonstick coating, and pressed or molded in a shaped cookware or other nonstick items or component. Various cooking devices can be pressed from the material, as well as oven or vehicle components.

The present invention relates to the technical field of cooking utensils, and in particular, to a nonstick utensil and its method of manufacturing. The nonstick utensil comprises a utensil substrate and a nonstick layer covering an inner surface of the utensil substrate; the material of the nonstick layer comprises black titanium dioxide. In these method of the present invention, an inner surface of a substrate of the nonstick utensil is covered with a material comprising black titanium dioxide by means of hot spraying, cold spraying or plasma spraying, so that a black titanium dioxide nonstick layer is formed. Compared to the prior art, instead of using a coating material, the present invention achieves the objective of nonstickness by forming nonstick layer comprising black titanium dioxide on a surface of a substrate, thanks to the low surface energy characteristic of black titanium dioxide.

Provided is a method for obtaining an item of cookware, including the following steps of: producing or providing a blank from a textured sheet of stainless steel having at least one textured face, stamping the blank in order to form a cap (2) having an inner face (3) and an outer face (4), the outer face (4) having parts in relief corresponding to the textured face of the blank, optionally, partially covering the outer face (4) of the cap (2), carrying out a mechanical finishing treatment of the free surface of the outer face (4) of the cap (2) in order to expose the stainless steel at the parts in relief of the free surface of the outer face (4) of the cap (2). Also provided is an item of cookware including a stamped cap (2) made of stainless steel having an inner face (3) and an outer face (4), wherein the outer face (4) of the cap (2) has a textured free surface (5).

Provided is an article of cookware and a method of making the same. The cookware has a multi-layer bonded composite wall structure having an inner metal layer and an outer metal layer, and a core layer between the inner layer and the outer layer. The core layer has at least two perforated graphite plates, each plate having a plurality of spaced-apart holes formed therethrough, and at least one intermediate metal element disposed between the at least two perforated graphite plates and extending through the plurality of spaced-apart holes of each of the at least two perforated graphite plates. The at least one intermediate metal element is metallurgically bonded to the inner layer and the outer layer at least through the plurality of spaced-apart holes.

The invention discloses a process for manufacturing a frying pan, which is characterized by comprising 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. The invention has the advantage of simple process and can be used to obtain a finished frying pan with better quality.

Described herein is a process for making a multilayer article comprising forming a first fluoropolymer layer in the absence of liquids by delivering particles from at least one gaseous fluid jet to a metal surface to impregnate the metal surface with a fluoropolymer to form a first fluoropolymer layer, wherein the particles comprise an abrasive particle, a binder, and a first fluoropolymer; coating the first fluoropolymer layer with a second fluoropolymer to form a second fluoropolymer layer and thereby forming a multilayered article; and sintering the multilayered article to form the release surface coated substrate.

A coating material, suitable for a self-cleaning coating on a part on or in a cooking, frying, baking or grilling appliance for removing residual foodstuffs without mechanical intervention, includes porous particles and a binder which connects the porous particles. The binder has precipitated, inorganic particles which are particles produced via a precipitation reaction and subsequent grinding.
