FIELD: chemistry.SUBSTANCE: invention refers to compositions of ceramic pastes, which are applicable for facing tile manufacturing. The ceramic paste for facing tile manufacturing contains, wt %: red-burning clay 63.9-66.0; broken tiles 0.1-1.0; phosphate rock 10.0-13.0; quartz sand 10.0-13.0; pegmatite 10.0-13.0. The manufactured products are dried to max. humidity 6% and burned at temperature 980-1020°C. Further, the tile surface is coated with a layer of transparent (if engobed) or opal glaze, and the tiles are burned once more at temperature 800-900°C.EFFECT: decreasing a burning point of the ceramic paste products.1 tbl |
