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.

The present invention relates to a method and a device for crushing glass bodies, in which the glass body is arranged in a microwave field so that the said glass body is crushed on account of the resulting thermal stresses. In addition, a local plasma which results in further thermal stresses, is produced on the surface of the glass body Since the glass body to be crushed does not come into contact with crushing means, for example rollers or the like, the pieces of broken glass cannot be contaminated by abrasion particles of the crushing means. The plasma permits a rapid and economic crushing of the glass bodies.

Method and device for crushing glass bodies by means of microwave heating

A high-frequency device for melting and refining inorganic compounds having a high-frequency oscillation system and a crucible. The high-frequency system includes an induction coil looping around the crucible and at least two oscillator circuits connectable in parallel to the induction coil and providing redundant high frequency energy. Each self-exciting oscillator includes one of the capacitors and the induction coil. The device may further include a power supply, a control cabinet having operating units, and a process control system.
