1. A process for producing a mould element comprising effecting a succession of layers by means of a barbotine comprising a refractory powder and a binder having hot and cold agglomerating properties, each deposit of a layer being followed by a powdering with a refractory powder, and effecting a firing, characterised in that it comprises forming a box (1) in which are mounted added parts (2) of a material which disintegrates upon firing, coating the box with a thin film of a mould-stripping agent, then effecting directly the deposit of the succession of layers so as to obtain a shell (3) having walls (31, 32), partitions (33) defining cavities (34) corresponding to the added parts and internal cavities, extracting said shell from the box and leaving the added parts embedded in the shell, these added parts being destroyed upon the firing. |
