Abstract
The invention relates to a skull pot () for melting, crystallizing or refining inorganic substances. Said pot comprises a pot wall (), a pot bottom (), an induction coil () which surrounds the pot wall () and by means of which high-frequency energy can be coupled into the content of the pot. The pot wall () is formed by a ring of metal pipes which can be connected to a cooling medium. Slits are embodied between adjacent metal pipes. The bottom () is provided with a discharge for the melt (). A sleeve () is allocated to the discharge. The admission end () of the sleeve () protrudes far into the inner chamber of the skull pot () in such a way that, during use, the melt () can be withdrawn through the crystallized bottom layer () in a controlled manner without the danger of impairing quality.
