Abstract

In the case of a method for manufacturing glass, with which molten glass is enclosed at least partially by precious metal walls or refractory metal walls, and with which the oxygen partial pressure of the molten glass is influenced by a treatment means to prevent disturbances, gas bubbles or other disturbances often form as a result of over-compensation. This over-compensation can be prevented by locating at least one probe (20) for determining the oxygen partial pressure at the interface—or close to the interface—of the glass melt and metal wall, and by regulating the influencing of the oxygen partial pressure in a safe range of the oxygen partial pressure with the treatment means using a regulating system (39, 45).
