Abstract

L’invention concerne la réalisation, sur un plateau (34) de support, d’un espace (76) annulaire dans une pâte à céramique recouvrant ce plateau, afin, par dépôts et cuissons successifs de couches de ladite pâte à céramique, de créer un fond d’une carapace (40) en céramique pour le moulage de pièces, le fond présentant ledit espace (76) annulaire. Pour cela, entre deux dépôts de ladite pâte à céramique, et sur le plateau, on va déformer ledit élément (82) annulaire déformable afin de briser la couche de céramique.
