Указанна цель достигаетс тем, что гЛушеное стекло, включающее Si02 , СаО, А1.,0з , MgO, , допол 871 . нительно содержит и Р следующем соотношении компонентов, мае, %: 43,05-53,47 42,0-51,0 2,30-3,05 А1,0з . 0,07-0,10 MgO 1,44-1,78 КагО 0,55-0,75 Кг О 0,17-0,27 Ре.Оз В табл, 1 приведены конкретные составы предлагаемых стекол. Дл получени глушеных стекол используют следующие исходные материалы , мае. %: перлит 10-22, известн к 70-100 и кварцевый песок 25-50„ Температура варки стекла 14001450 .°С, врем вьщержки 2ч. Готовую стекломассу можно отлить или прессовать . Полученные издели (плитки) отжигают при 650°С с вьздержкой 2 ч„ Охлаждение производ т со скоростью 60°С/ч до 25°С. Плитки глушеного стекла имеют светло-голубую окраску, глушение происходит во врем выработки и в объеме. В табл. 2 приведены физико-химические свойства стекол. Степень глушени определ ют визуально . Как видНо из табл.2, предлагаемое глушеное стекло по сравнению с известными имеет повешенные химстойкость и механическую прочность, полную степень глушени . Таблица 1The invention relates to the glass industry and can be used as a decorative cladding material. Known jammed glass f1 of the following composition, weight. %: SiO, 64-73 18-30 0.2-4.5 .0.5-5.0 1.0-3.5 0.3-7.0 0.5-1.5 CuO0.3- 5 Limestone composition is characterized by a high temperature of boiling and production, mechanical strength and degree of damping. . The closest to the proposed technical result and achieved the result is L2j jammed glass of the following composition, weight SiOj 43.29-50.92 35.68-41.96 0.10-4.00 2.74-3.99 MgO4 , 37-13,04. The disadvantages of this glass are relatively low mechanical strength (580-650 kg / cm). IMHAMIC STABILITY The purpose of the invention is to increase mechanical strength and chemical resistance. This goal is achieved in that the perforated glass includes SiO2, CaO, A1., 0Z, MgO,, dopad 871. It also contains the following ratio of components, May,%: 43.05-53.47 42.0-51.0 2.30-3.05 A1.0 s. 0.07-0.10 MgO 1.44-1.78 KagO 0.55-0.75 Kg O 0.17-0.27 D OO Table 1 shows the specific compositions of the proposed glasses. The following starting materials, May, are used to obtain worn glass. %: perlite 10-22, limestone to 70-100 and quartz sand 25-50 "Glass melting temperature 14001450. ° С, holding time 2h. The finished glass melt can be molded or pressed. The obtained products (tiles) are annealed at 650 ° C with an extract of 2 hours. The cooling is carried out at a rate of 60 ° C / h to 25 ° C. Tiles of jammed glass have a light blue color, and killing occurs during production and in bulk. In tab. 2 shows the physico-chemical properties of glasses. The degree of damping is determined visually. As can be seen from Table 2, the proposed muffled glass, as compared with the known ones, has chemical resistance and mechanical strength, and a complete degree of killing. Table 1
