1. Verfahren zur Herstellung eines Glases aus Kieselsäure, Tonerde, Kalk, Borsäure und Alkali, das chemischen Einwirkungen verhältnismäßig gut widersteht und mindestens zur Hälfte aus Kieselsäure besteht, dadurch gekennzeichnet, daß als weitere Bestandteile 4 bis 15 Prozent Tonerde, 3 bis 11 Prozent Kalk, 5 bis 15 Prozent Borsäure und 4 bis 14 Prozent Alkali in einem solchen gegenseitigen Verhältnis verwendet werden, daß die Gesamtmenge von Tonerde und Kalk mindestens die Hälfte und höchstens das Fünffache des Borsäuregehalts beträgt.1. Process for the production of a glass from silica, alumina, lime, Boric acid and alkali, which withstand chemical effects relatively well, and at least half of them are made of silica consists, characterized in that 4 to 15 percent clay, 3 to 11 percent lime, 5 to 15 percent Boric acid and 4 to 14 percent alkali in such a mutual ratio be used that the total amount of clay and lime at least half and at most five times that Boric acid content.
2. Verfahren nach Anspruch 1 unter Verwendung von 8 bis 12 Prozent Natron, dadurch gekennzeichnet, daß von Tonerde mindestens 6 und höchstens 12 Prozent genommen werden.2. The method according to claim 1 using from 8 to 12 percent baking soda, characterized in that of clay a minimum of 6 and a maximum of 12 percent are taken.
