Zusammenfassung:FIELD: compositions for nephroted majolica glazes for decoration of products from ceramics. SUBSTANCE: glaze comprises SiO2,Al2O3, MgO and also waste of electrovacuum industry (broken kinescope cubes), ZnO and at least one of colorants such as pyrite cinder, CaO, CuO, FeO, Cr2O3, MnO and NiO, ratios of components being as follows, wt.%: SiO2, 10-15, Al2O3, 6-9 MgO, 1.6-2; ZnO, 1.2-4; waste (broken kinescope tubes), the balance. Total SiO2 content is not higher than 59.83 wt.%. 5-10 wt.% of pyrite cinder are added to form brown wear-resistant coating, other colorants are added in amount up to 20 wt.%. Optimum amount of colorant additives is 7 wt.%. EFFECT: reduced manufacturing cost price of glaze. 1 tbl
