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 (10) having a refining region (3) for refinement of the glass melt and a noble metal member for producing oxygen in the melt. The noble metal member (40) 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.
