Method for decorating a cooking vessel comprising a substrate, said method comprising the following steps: - providing a substrate comprising two opposite surfaces (21, 22); - applying at least one thermostable base composition over an area of one of the surfaces of the substrate to form at least one base layer, the thermostable base composition being a sol-gel composition, or an aqueous slurry of enamel frit or an aqueous composition comprising a fluorocarbon resin dispersion; - applying at least one thermostable decorative composition on the base layer to form at least one decorative layer, the thermostable decorative composition being a sol-gel composition, or an aqueous slurry of enamel frit or an aqueous composition comprising a fluorocarbon resin dispersion; - mechanically treating the surface of the decorative layer in order to produce a decorative, the mechanical treatment comprising a removal and/or a movement of a portion of the thermostable decorative composition by the pressure and the movement of a tool or of a compressed air jet on the surface of the decorative layer; - drying of the decorative layer mechanically treated when the thermostable decorative composition is an aqueous slurry of enamel frit or an aqueous composition comprising a fluorocarbon resin dispersion, and potentially when the thermostable decorative composition is a sol-gel composition; and - thermal densification treatment of the coated substrate, no thermal densification treatment of the coated substrate being carried out between the application step of the thermostable base composition and the application step of the thermostable decorative composition, and the cooking vessel being a vessel of which the surface not coated at least by the decorative layer is a concave interior surface designed to be positioned on the side where food may be placed into said vessel, and an opposite second of said surfaces is a convex exterior surface designed to be positioned toward a heat source. - providing a substrate comprising two opposite surfaces (21, 22); - applying at least one thermostable base composition over an area of one of the surfaces of the substrate to form at least one base layer, the thermostable base composition being a sol-gel composition, or an aqueous slurry of enamel frit or an aqueous composition comprising a fluorocarbon resin dispersion; - applying at least one thermostable decorative composition on the base layer to form at least one decorative layer, the thermostable decorative composition being a sol-gel composition, or an aqueous slurry of enamel frit or an aqueous composition comprising a fluorocarbon resin dispersion; - mechanically treating the surface of the decorative layer in order to produce a decorative, the mechanical treatment comprising a removal and/or a movement of a portion of the thermostable decorative composition by the pressure and the movement of a tool or of a compressed air jet on the surface of the decorative layer; - drying of the decorative layer mechanically treated when the thermostable decorative composition is an aqueous slurry of enamel frit or an aqueous composition comprising a fluorocarbon resin dispersion, and potentially when the thermostable decorative composition is a sol-gel composition; and - thermal densification treatment of the coated substrate,
