Abstract

According to one example of embodiment of the invention a ceramic pre-moulding 81 of stable form is pressed from ceramic composition in powder form in a first isostatic pressing action, at least a part of its surface being formed in contact with rigid shaping surfaces 42. The pre-moulding 81 thus obtained is then--possibly after glazing-subjected to a higher pressure, in a further pressing operation on all sides and then fired in a ONCE-ONLY quick-firing method.
