FIELD: production of building materials. SUBSTANCE: broken glass and boric acid are added to ceramic mass comprising slime from galvanic manufacture and clay in the following ratio of components, weight %: galvanic slime, 0.82; clay, 82.42; broken glass, 16.48; boric acid, 0.28. Annealing point is 850 C, compression strength limit value is 17.2 MPa. Invention can be used for making wall ceramics articles. Invention provides decrease of annealing point, enhancement of compression strength value and decrease of heavy metals washing out. EFFECT: improved properties of ceramic mass. 2 tbl
