Abstract

Bei einem Verfahren zum Herstellen von Glas, bei dem geschmolzenes Glas zumindest teilweise von Edelmetallwänden oder Refraktärmetallwänden umgeben ist und bei dem der Sauerstoffpartialdruck des geschmolzenen Glases zum Vermeiden von Störungen mittels eines Behandlungsmittels beeinflusst wird, entstehen häufig durch Überkompensation wiederum Gasblasen oder andere Störungen. Diese Überkompensation lässt sich dadurch verhindern, dass man mindestens eine Sonde (20) zum Bestimmen des Sauerstoffpartialdrucks an der Grenzfläche bzw. dem grenzflächennahen Bereich von Glasschmelze/Metallwand anordnet und dass man das Beeinflussen des Sauerstoffpartialdrucks mit dem Behandlungsmittel mittels einer Regelung (39, 45) in einem sicheren Bereich des Sauerstoffpartialdrucks regelt.
