摘要：
The invention relates to a method and a device for refining a glass melt, using negative-pressure apparatus. According to the invention, the glass melt is fed to a refining bench by means of an uptake pipe and is discharged from the refining bench by means of a downpipe, a negative pressure being created over the flow of glass in the refining bench. The invention is characterised in that the uptake pipe and/or the downpipe and/or the refining bench has/have at least one component consisting of at least one refractory metal and/or of a refractory metal alloy as the glass contact material.
