Abstract

A crucible, especially for containing melts, has multi-layered walls with an inner core of heat resistant material. A continuous coating layer of temperature resistant material is supported on the core. The coating layer at least partially defines a reservoir for melts to be contained in the crucible, and is composed of material resistant to attack by hot melts.
