WIPO Patent Application WO/2003/091630

A1

A method for manufacturing a heating cooking utensil, characterized in that a surface layer is formed by a method comprising a step of applying an aqueous coating fluid containing water and a water-soluble zirconium compound or a water-dispersible zirconium oxide sol having an average particle diameter of 50 nm or less on the surface of at least the portion comprising a heat-resistant base material of the heating cooking utensil, and a step of firing the resultant surface. The method can be used for manufacturing, at a low cost and with safety, a heating cooking utensil which exhibits excellent durability even in the use in a place which is frequently exposed to a high temperature and also to water, a salt and the like, such as one around a kitchen range or in a grill, and allows a scorched material adhered to the surface thereof to be easily removed only by immersion into water and then light rubbing by a finger or a dishcloth.
