Abstract
242,568. Jenaer Glaswerk Schott & Gen., Schott, O., and Thiene, H. Aug. 4, 1925. Production of metal.-A glass which is insensitive to abrupt temperature change contains at least 45 per cent of silica, from 2 per cent to 15 per cent of boron trioxide, and from 4 per cent to 30 per cent of magnesia and lime together, and is characterized by the fact that it contains from 20 per cent to 30 per cent of alumina and not more than 8 per cent of alkali oxide. The magnesia or lime may be replaced .by barium oxide or zinc oxide in equivalent quantities, and lead oxide or antimony oxide may be introduced in quantities not exceeding 6 per cent. Opal glass may be produced by the addition of substances usually used for this purpose.
