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. ^ 2 tbl |
