Date Dec. 19, 1985.During ceramic casting for the production of a molten bath it is often observed that the fire-resistant material becomes eroded and/or solid oxide phases are deposited. Both phenomena interfere with the smooth outflow of the molten bath. The present invention is intended, therefore, to provide an outflow which is stable in shape even when a molten bath is passed through, especially in multiple-sequence casting. To this end, the invention provides for ceramic casting with an envelope (10, 14) which is at least partly external and an internal insert (11, 14, 53) at a distance from the envelope (10, 14), the insert ( b 11, 14, 53) and envelope being connected together.
