ABSTRACT:
A ceramic article is electrophoretically slip-cast by placing an aqueous suspension of a ceramic material in a multi-part mould, each part of which has an electrically conductive porous carbonaceous operative surface conforming to the desired outside surface of a respective part of the article, the carbonaceous component of the surface region being made of particles of from 70 .mu.m to 200 .mu.m maximum diameter, the parts of the mould being electrically insulated from one another, each part being intermittently made anodic with respect to the suspension, at least one part at any time being cathodic (except for possible intervals when no part is anodic). Thus a model horse is made from the mould parts of FIG. 4 which are electrically charged in the following sequence, 1 minute each phase and all repeated at least once:
