Description

Verfahren zum Ätzen keramischer Werkstücke für Dekorzwecke Das Ätzen von silicatisch.en Stoffen erfolgt im allgemeinen so, daß die zu ätzenden Stücke mit Asphalt oder Asphaltlacken ;abgedeckt und dann in Flußsäure getaucht oder mit einer flußsäurehaltigen Paste biestrichen werden. Das Arbeiten mit Flußsäure ist aber mehr oder weniger gefährlich. Es ist ,auch zur Herstellung von muhen Siliicatoberfläc'hen bekannt, Quarz durch ein. Flußmittel festzubrennen und dann mechanisch wieder ,abzureiben.Process for etching ceramic workpieces for decorative purposes Etching of silicate substances is generally done in such a way that the pieces to be etched with asphalt or asphalt paint; covered and then dipped in hydrofluoric acid or with a hydrofluoric acid paste. Working with hydrofluoric acid is but more or less dangerous. It is also used for the production of low-level silicate surfaces known quartz by a. Burning the flux on and then mechanically rubbing it off again.

Bei dem Verfahren nach der Erfindung wird von der Behandlung mit Flußsäure abgegangen, und das Abdecken mit Asphalt .oder Asphaltlacken kommt in Fortfall. Die Ätzung wird durch weit weniger gefährliche oder sogar ungefährliche Mittel ausgeführt. Dias zu ätzende Muster wird z. B. nach dem bekannten Stahldruckverfahren auf das keramische Werkstück aufgetragen. Als Druckfarbe werden anorganische Salze der Alkalien und Erdalkalien, ferner keramische Farben, Metalle oder Metallverbindungen verwendet, die beim nachfolgenden Brennen tief in die Oberfläche eindringen und sich mit dem Werkstoff zu verhältnismäßig leicht löslichen Stoffen ver:.)inden.In the method according to the invention, treatment with hydrofluoric acid is used removed, and covering with asphalt or asphalt paint is no longer necessary. The etching is carried out by far less dangerous or even harmless means. The pattern to be etched is z. B. according to the known steel printing process on the ceramic workpiece applied. Inorganic salts of alkalis are used as printing inks and alkaline earths, furthermore ceramic colors, metals or metal compounds are used, which penetrate deeply into the surface during the subsequent firing and get in contact with the Relate the material to relatively easily soluble substances:.) Inden.

Diese beim Erhitzen entstandenen Reaktionskörper werden dann durch verschiedene Säuren, wie Essigsäure, Salzsäure, zum Teil sogar in schwacher Konzentration, wieder ausgelöst. In der Oberfläche der Werkstücke entstehen dadurch Vertiefungen, die durch Überziehen mit Gold, Silber oder einer anderen Farbe in bekannter Weise als Verzierung wirken.These reaction bodies produced during heating are then through various acids, such as acetic acid, hydrochloric acid, sometimes even in weak concentrations, triggered again. This creates depressions in the surface of the workpieces, by plating with gold, silver or another color in a known manner act as an ornament.
