A process for shaping parts from ceramic powder that comprises the steps of (1) forming a concentrated mixture in excess of 40% ceramic solids by volume, the mixture comprising ceramic powder, a gel forming material chosen from the class of polysaccharides known as 'agaroids', and a gel forming material solvent and being formed in a blender that provides a shearing action and is heated to raise the temperature of the mixture to about 70.degree. C. to 100.degree. C.; and (2) molding the mixture at a temperature sufficient to produce a self-supporting structure comprising the powder and gel. The parts exhibit excellent green strength and are rapidly fired without cracking, distortion or shrinkage problems.
