The invention relates to the glass industry, in particular to the production of narrow- and wide-necked container glass from semi-white to dark green and dark green and brown tones for the brewing, distillery and wine industry.The invention consists in that the container glass contains SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, TiO2, MnO, FeO, SO3, Cr2O3, at the same time the ratio FeO/Fe2O3 is 0.28…0.39, and the content of components is, mass %: SiO2 70.05…71.72; Al2O3 1.37…1.98; Fe2O3 0.328…0.691; CaO 7.88…10.92; MgO 3.01…3.33; Na2O 12.46…14.04; K2O 0.15…0.92; TiO2 0.001…0.055; MnO 0.001…0.015; FeO 0.092…0.264; SO3 0.027…0.053; Cr2O3 0.120…0.170.As raw material for the corresponding charge can be used basalt article production waste.The result of the invention consists in increasing the resistance of the glass to thermal shock, improving the performance of“color tone”and“color purity”indexes when staining the glass in colors from semi-white (Half flint) to dark green and dark green-brown (Dead leaf and Cuvee), that ensures the safety of the content in the proposed container glass. |
