Description

Verfahren zum Vergüten von Glas, Glasuren und Emails In dein Patent 644 097 ist ein Verfahren beschrieben, nach dem die chemische Widerstandsfähigkeit von Glas, Glasuren und Emails dadurch verbessert wird, daß man den dünnflüssigen Schmelzen Wasserdampf einverleibt, was z. B. schon beim Niederschmelzen der Rohstoffe geschehen kann. Es war darauf hingewiesen worden, daß man dann dafür sorgen muß, daß der Wasserdampf während der weiteren Behandlung der Schmelze nicht wieder lierausdiffundiert. Ohne entsprechende Vorkehrungen würde der Wasserdampf in der verhältnismäßig langen Geit, während der z. B. eine Glasschmelze in der Läuter- oder Abstehzone in relativ dünnflüssigem Zustand sich befindet, ohne weiteres entweichen. Aber auch während der Verarbeitung der Schmelze durch Formung steigt die Zähigkeit nicht so plötzlich an, daß nicht ein Herausdiffundieren des Wasserdampfes wenigstens zuin Teil zu erwarten wäre. Überraschenderweise zeigte sich jedoch, daß es nicht notwendig ist, die Verarbeitung oder Abkühlung der Schmelzen in einer besonders wasserdampfhaltigen Atmosphäre vorzunehmen; die in obigem Patent beschriebene Vergütung wurde in vollem Maße 'erbalten, wenn man- die Schmelzen in normaler Luft oder in einer sonstigen wasserdampffreien Atmosphäre verarbeitete bzw. abkühlte.Process for tempering glass, glazes and enamels In your patent 644 097 describes a method according to which the chemical resistance of glass, glazes and enamels is improved by using the thin Melting water vapor incorporated what z. B. already when the raw materials are melted down can happen. It was pointed out that one must then see to it that that the water vapor does not diffuse out again during the further treatment of the melt. Without appropriate precautions, the water vapor would last for a relatively long time Geit, during the z. B. a glass melt in the refining or standing zone in relative liquid state is, easily escape. But also during When the melt is processed by molding, the toughness does not increase so suddenly suggests that at least some of the water vapor will not diffuse out were. Surprisingly, however, it was found that it is not necessary to carry out processing or to cool the melts in an atmosphere that is particularly rich in water vapor; the compensation described in the above patent was obtained in full if man- the melts in normal air or in another atmosphere free of steam processed or cooled.
