CRUDE MIXTURE FOR THERMAL DECORATING SURFACES OF NON-FIRED MATERIALS AND ARTICLES Russian patent published in 2011 - IPC C04B41/45 B28B11/04 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of crude mixtures for thermal decorating surfaces of artificial stone non-fired materials and articles, mainly concrete and lime-sand articles. The crude mixture for thermal decorating surfaces of non-fired materials and articles, which contains low-melting frit, clay and a colouring additive, also contains mineral binder, wherein the low-melting frit, clay and colouring additive are separately ground using a try technique to specific surface area of 3000-5000 cm²/g and are then mixed with mineral binder, in the following ratio of components in wt %: low-melting frit 55-70, clay 0.5-5.0, mineral binder 15.0-30.0, colouring additive 0.1-10.0.

EFFECT: obtaining uniform glass-like coating on the surface of non-fired materials and articles.
