Abstract
The device for manufacturing glass, in which bubble formation on precious metal components is prevented, has a precious or refractory metal wall () at least partially surrounding a glass melt from which the glass is made, a first electrode pair () for measuring oxygen partial pressure at an interface between the glass melt and the wall to obtain an actual value, a second electrode pair () for measuring an oxygen partial pressure in the glass melt to obtain a set point value and a regulating system () for adjusting the oxygen partial pressure at the interface according to a comparison between the actual value and the set point value, so that the oxygen partial pressure at the interface is within a safe range.
