Apparatus and process for refining glasses or glass ceramics

摘要

Apparatus for refining glass and glass ceramics comprises a melt sink (1) with refining vessels (3, 4) connected to the sink. At least one of the vessels is constructed of a number of metal tubes according to the Skull principle, and a high frequency device to inductively couple high frequency energy into the vessel. The tubes have a coolant connection. An Independent claim is also included for a process for refining glass or glass melts comprising melting the substances and then refining in two stages so that the refining is carried out in at least one stage according to the Skull principle with inductive heating of the melt by irradiation of the high frequency energy.
