Description

Verfahren zur Herstellung von matten Emails Für die Herstellung von matten Emails sind bereits eine ganze Reihe verschiedener Wege vorgeschlagen worden, z. B. Ätzen der Emailschicht, Behandeln mit einem Sandstrahlgebläse oder durch Zusatz zum Email von in diesem unlöslichen Bestandteilen oder die beim Schmelzprozeß unlösliche Verbindungen ergeben, wie z. B. Überschuß an Tonerde, Schwefelverbindungen u. dgl. Man erhält auf diese Weise Emails, die doch immer einen einseitigen Glanz aufweisen.Process for the production of matt enamels For the production of dull emails, a number of different ways have already been suggested z. B. Etching of the enamel layer, treatment with a sandblasting blower or by addition to the enamel of constituents which are insoluble in this or those which are insoluble in the melting process Connections result, such as. B. Excess of clay, sulfur compounds and the like. In this way, you get enamels that always have a one-sided sheen.

Nach dem nachfolgend zu beschreibenden Verfahren ist es möglich, mit den billigsten Rohmaterialien und einfachster Arbeitsweise absolut matte Emails herzustellen, die ein vollkommen diffuses Licht bei hoher Weiße reflektieren und nach keiner Richtung irgendwelche Spiegelung aufweisen.Using the procedure described below, it is possible to use the cheapest raw materials and the simplest way of working absolutely matt enamels that reflect a completely diffuse light with high whiteness and have no reflection in any direction.

Dies wird dadurch erreicht, daß man sehr große Mengen von tonerdehaltigen Bestandteilen des Emails, wie Ton, Kaolin oder Feldspat, mit einer kleinen Menge Email aufträgt. Hierbei wird weit über die bisher bekannten Grenzen an solchen tonerdehaltigen Bestandteilen hinausgegangen. Es wird hierbei wie folgt verfahren: Auf eine normale Emailschicht wird eine Mischung von schwer schmelzbaren, tonerdehaltigen Bestandteilen des Emails, wie Feldspat, Kaolin, Ton, gebrannter Kaolin usw., mit einer io°/o Email aufgetragen und eingebrannt. Dieser Mischung kann man Trübungsmittel in der üblichen Menge von etwa 6°/0, ebenso wenn man eine farbige, matte Emailschicht haben will, Farbe zur Mühle zusetzen. Die so hergestellten Waren mit matten Emails können dann nach dem üblichen Verfahren mit matten oder auch glänzenden Emails anderer Farbe dekoriert werden, wodurch besonders schöne und neue Effekte erzielt werden können.This is achieved by using very large amounts of alumina Components of the enamel, such as clay, kaolin or feldspar, with a small amount Email applies. This is far beyond the previously known limits of such alumina Components went out. The procedure is as follows: On a normal The enamel layer is a mixture of difficult-to-melt, alumina-containing components of the enamel, such as feldspar, kaolin, clay, burnt kaolin, etc., with an io% enamel applied and baked. This mixture can be used in the usual opacifiers Quantity of about 6%, also if you want a colored, matt enamel layer, Add color to the grinder. The goods produced in this way with matt enamels can then using the usual method with matt or glossy enamels of a different color can be decorated, whereby particularly beautiful and new effects can be achieved.
