FIELD: composition of glassy covering.

SUBSTANCE: the present innovation deals with glassy coverings for applying certain marking signs, illustrations onto ceramic articles, materials based upon hydraulic, liquid-glass, phosphate astringents, and glass. The suggested glassy covering contains CaO, Al₂O₃, Cr₂O₃, SiO₂ and additionally TiO₂, MgO, SrO at the following ratio of the components mentioned, weight%: CaO 35.0-40.0; Al₂O₃ 5.0-10.0, Cr₂O₃ 5.0-10.0; TiO₂ 5.0-10.0; MgO 5.0-10.0; SrO 5.0-10.0; SiO₂ 20.0-30.0. The innovation enables to increase the resistance of glassy covering to impact.

EFFECT: higher efficiency.
