Abstract
An apparatus for making glass in which a glass melt is refined in a vessel with oxygen is described. It includes a melt-containing vessel ( ) having a refining region ( ) for refinement of the glass melt and a noble metal member for producing oxygen in the melt. The noble metal member ( ) has an outer side facing the glass melt and an inner side facing away from the glass melt washed with and acted on with oxygen. Oxygen-containing bubbles are vigorously generated on the outer side of the noble metal member facing the glass melt when the inner side is washed with the oxygen.
