Description

Fritte zur Herstellung getrübter Emails Es ist bekannt, Zinksulfid als Mühlentrübungsmittel für Emails zu verwenden. Man erhält jedoch nach diesem Verfahren meist stark gelb verfärbte und matte Emails oder Glasuren..Frit for the production of cloudy enamels It is known, zinc sulfide to be used as a mill opacifier for enamels. However, after this one obtains Process mostly strongly yellow discolored and matt enamels or glazes.

Es wurde nun gefunden, daß man diesen Übelstand beheben kann, wenn man Zinksulfid oder Zinksulfid bildende Stoffe und erforderlichenfalls zusätzliches Zink und/oder Zinkverbindungen mit in das Email oder den Glasurversatz einschmilzt. Die nach diesem Verfahren erschmolzenen Email-oder Glasurfritten sind vollkommen transparent; enthalten sie Alkalititansilicat als Flußmittel, so zeichnen sie sich außerdem noch durch erhöhten Glanz aus. Die Fritten werden mit den üblichen Mühlenversätzen, wie Ton und Schwebemittel, vermahlen und auf die zu emaillierenden oder zu glasierenden Gegenstände aufgetragen und wie üblich eingebrannt. Hierbei kommt das in der Schmelze gelöste Zinksulfid wieder zur Ausscheidung, und man erhält vollkommen dichtgetrübte Emails oder Glasuren, die den bisher gebräuchlichen in keiner Weise nachstehen.It has now been found that this deficiency can be remedied if zinc sulfide or zinc sulfide-forming substances and, if necessary, additional ones Zinc and / or zinc compounds melt into the enamel or the glaze offset. The enamel or glaze frits melted by this process are perfect transparent; if they contain alkali titanium silicate as a flux, they stand out also characterized by increased gloss. The fries are made with the usual mill offsets, such as clay and suspended matter, ground and applied to the enamelling or glazing Objects applied and baked in as usual. Here it comes in the melt dissolved zinc sulfide again to be excreted, and you get completely opaque Enamels or glazes that are in no way inferior to those that have been used up to now.
