A method for manufacturing a porcelain washer 0.030 inch thick and 0.495 inch ± 0.003 inch inside diameter is described. Strength sufficient to allow the handling and trimming of the raw parts is secured by using waxes as the temporary binder of the dry ceramic materials, and forming under higher pressure. As the plasticity necessary for forming is obtained with wax, the stresses and resulting deformation incident to the use of clay plasticized with water are eliminated. Lower, more uniform shrinkage with resultant closer dimensional control is thus obtained.
