ABSTRACT:
In the method of making glass a glass melt is formed from starting materials in a melt apparatus, which includes at least one metal part having a metal surface in contact with the glass melt in a first region of the glass melt having a predetermined oxygen partial pressure. This method includes suppressing oxygen bubble formation in the glass melt at a contacting surface between the metal surface and the glass melt; immersing an electrode in a second region of the glass melt not including the first region, which has a lower oxygen partial pressure than in the first region, and electrically conductively connecting the electrode and the at least one metal part. An apparatus for performing the method is also described as well as glasses made by the method.
