Zinkoxyd, Zinnoxyd, Zirkonoxyd, Titansäure, Kieselsäure oder andere wcissgcfärbte, feuer- beständige Materialien oder entsprechende Gemische der genannten Stoffe zusetzt und das Gemisch glüht. Es genügen schon Zusätze von 10% berechnet auf das Gemisch von Aluminium- und Magnesiumoxyd bzw. Aluminiumoxyd und Zinkoxyd, d. h. bei Verwendung von r) % des Trübungsmittel auf die Emailmasse berechnet l"/o, um erheblich stärkere Trubungsetfekto gegenüber den geglühten, reinen Gemischen zu erzielen. Das Plus an Wirkung ist grösser, als dass es sich um einen rein additiven Effekt handeln kann.
Es bleibt dahingestellt, ob die Zusätze lediglich die Trübung verstärken oder aber auch die Aufnahmefähigkeit des Trübungsmittels in dorn Email verbessern,

spinell, die ebenfalls weiss gefärbte Verbindungen darstellen, für Trübungszwecke gänzlich unbrauchbar sind ; sie zersetzen sich nämlich beim Einschmelzen mit dem Deckemail vollkommen.
Im Gegensatz hiezu hat sich Zinkspinell als ein gutes Trübungsmittel erwiesen, das aber wegen seiner Giftigkeit nur für sogenannte kosmetische Emaille Verwendung

Durch die neue Erfindung ist ein wichtiger, wirtschaftlicher Fortschritt erzielt. Es leuchtet dies ohneweiters ein, wenn man bedenkt,dass die geglühten Gemische sich viel

EMI2.1
Zinc oxide, tin oxide, zirconium oxide, titanic acid, silica or other white-colored, fire-resistant materials or corresponding mixtures of the substances mentioned are added and the mixture glows. Additions of 10%, calculated on the mixture of aluminum and magnesium oxide or aluminum oxide and zinc oxide, are sufficient. H. when using r)% of the opacifier on the enamel mass, l "/ o is calculated in order to achieve a considerably stronger opacity effect compared to the annealed, pure mixtures. The plus in effect is greater than it can be a purely additive effect.
It remains to be seen whether the additives only increase the opacity or also improve the absorption capacity of the opacifier in thorn enamel,
These properties of annealed mixtures of aluminum and magnosium oxide or aluminum and zinc oxide, irrespective of whether they are used pure or with the additives mentioned, by no means had to be given in advance, otherwise they already had a technical use in the numerous attempts to create a substitute for tin oxide
EMI2.2
spinel, which are also white-colored compounds, are completely useless for clouding purposes; they completely decompose when they are melted down with the cover enamel.
In contrast to this, zinc spinel has proven to be a good opacifier, but because of its toxicity it is only used for so-called cosmetic enamel use
EMI2.3
The new invention has made important economic progress. This is obvious when you consider that the annealed mixtures differ a lot
