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.

KAISERLICHESIMPERIAL PATENTAMTPATENT OFFICE gut widersteht.resists well. Durch die Erfindung wird ein Glas erzielt, das die bekannten Gläser von etwa denselben Herstellungskosten und von derselben allgemeinen Verwendbarkeit an Widerstandsfähigkeit gegen chemische Einflüsse weit übertrifft. . Vermöge dieses Vorzuges ist das neue Glas z. B. für chemische Geräte und für Wasserstandsröhren geeignet. Es handelt sich um ein Glas, in welchem sich als BestandteileThe invention achieves a glass that is approximately the same as the known glasses Manufacturing costs and of the same general applicability in terms of resistance far exceeds chemical influences. . The new glass is by virtue of this advantage z. B. suitable for chemical devices and for water level tubes. It is a matter of a glass in which as constituents ίο Kieselsäure, Tonerde, Kalk, Borsäure und Alkali vereinigt finden, was nicht neu ist.ίο silica, clay, lime, boric acid and Finding alkali united that is not new. Bei der Herstellung eines Glases nach vorliegender Erfindung finden wie bei bekannten Gläsern mehr als 50 Prozent Kieselsäure Ver-Wendung. Es werden weiter in den Glassatz eingeführt: 4 bis 15 Prozent Tonerde, 3 bis 11 Prozent Kalk, 5 bis 15 Prozent Borsäure und 4 bis 14 Prozent Alkali. Dabei soll aber die Menge von Tonerde und Kalk zusammen nicht kleiner als die Hälfte und nicht größer als das Fünffache der Borsäuremenge sein.In the manufacture of a glass according to the present invention, as in known ones Glasses use more than 50 percent silica. There are further introduced into the glassware: 4 to 15 percent alumina, 3 to 11 percent lime, 5 to 15 percent boric acid and 4 to 14 percent alkali. But it should the amount of clay and lime taken together is not less than half and not greater than five times the amount of boric acid. Als Alkalibestandteil wird zweckmäßig Natron genommen. Nach den bei der Ausarbeitung der Erfindung gewonnenen Erfahrungen zeigt das neue Glas eine besonders große chemische Widerstandsfähigkeit, wenn man in der Wahl der Natronmenge und der Tonerdenmenge den oben angegebenen Grenzen nicht zu nahe kommt, wenn man also bei einem Natrongehalt von 8 bis 12 Prozent von Tonerde nicht weniger als etwa 6, aber auch nicht mehr als etwa 12 Prozent nimmt.Soda is expediently used as the alkali component. According to the in drafting The experience gained from the invention shows that the new glass has a particularly great chemical Resilience, if you choose the amount of baking soda and the amount of clay Do not come too close to the limits given above, if you use clay with a sodium content of 8 to 12 percent takes no less than about 6, but also no more than about 12 percent. Während die angegebenen Bestandteile notwendig zu dem neuen Glase zu verwenden sind, ist natürlich die Hinzufügung einer kleinen Menge eines oder mehrerer anderer Stoffe, die z. B. den Zweck haben mag, das Glas zu färben, nicht ausgeschlossen.While the specified ingredients are necessary to use the new glass is of course the addition of a small amount of one or more other substances the z. B. may have the purpose of coloring the glass, not excluded.
