Abstract

A method for the refining of glass by means of high temperatures in a skull crucible is provided. The method includes introducing a glass melt in the skull crucible through an inlet disposed at an upper region of the skull crucible, heating the skull crucible by irradiation of high-frequency energy, and discharging the glass melt from the skull crucible through an outlet disposed at the upper region, the outlet being disposed at a place essentially lying opposite the inlet.
