ABSTRACT:
A multi-shelled melt container is disclosed for liquefying and crystallizing substances which comprises at least an inner shell and a bearing shell. While the inner shell--which has a thin wall in comparison to the wall of the bearing shell--consists of an inert material with respect to the melt, the bearing shell serves exclusively to fixate and support the inner shell and is correspondingly constructed in a mechanically stable fashion. The device can also comprise means to pump the melt over into a collection vessel.
