Abstract

1. A method of separating a refractory moulded shell (1) from a casting pattern (2), in which the moulded shell (1) is formed adjacent to the surface of the casting pattern (2) by mechanically and/or pneumatically compacting, and possibly thermo-setting, a fine-grained mineral mass the particles of which are encased by an organic or unorganic binding agent, and in which air pressure above atmospheric pressure is applied between the casting pattern (2) and the mould shell (1), characterized in that air pressure below the atmospheric one is applied at the surface of the moulded shell (1).
