Improvements in the manufacture of ceramic pieces, characterized by the fact that, said parts being obtained by molding in ceramic material, flat plates are determined peripherally bordered by a succession of cylindrical surfaces of height defined by that of the plate, whose radii of curvature and arc lengths are equal for all of them, so that these surfaces are linked to each other according to points of tangency, determinants of inflection points, and according to points of intersection that determine curvilinear vertices whose angles are of less than 180º, being Attachable the concave parts of one piece with the convex parts of another.
