Abstract
The invention relates to a skull pot for melting or refining glass or glass ceramics, comprising a pot wall ( ), a pot base, and an induction coil ( ) which surrounds said pot wall and through which high-frequency energy can be coupled into the contents of the pot. The pot wall is made up of a ring of metal pipes ( ) which can be connected to a cooling medium, slot-type intermediate chambers being provided between adjacent metal pipes. The pot base has a run-off for the melt. The metal pipes ( ) that form the pot wall ( ) arm short-circuited with each other above the base in order to increase the degree of efficiency of the skull pot and especially, in order to even out the temperature profile of the melt throughout the depth of the melt.
