ENAMELLED MINERAL SUBSTRATE AND METHOD OF ITS PRODUCTION Russian patent published in 2024 - IPC C03C17/04 C03C8/14 B41M1/34 

FIELD: various technological processes.

SUBSTANCE: invention relates to a mineral substrate with inorganic enamel on at least one of its surfaces, which can withstand metal friction, which can be used as a surface of a kitchen device or tabletop. Inorganic enamel has a total surface roughness less than or equal to 2 mcm, and the edge of the inorganic enamel protruding from the surface of the glass-ceramic substrate has a topographic slope value expressed as a percentage less than or equal to 1.4%. Substrate is a glass-ceramic substrate or a mineral glass substrate. Enamel is applied onto the substrate by means of jet printing.

EFFECT: limiting the appearance of metal marks on the substrate when in contact with metal utensils.
