Abstract: A method and composition for combining ceramic powder and binder to form green elements suitable for shaping and firing uses dry blending techniques. The binder includes a particulate wax component that is not melted in order to combine it with the ceramic powder, but rather, the wax component is combined in particulate form with the ceramic powder. The particulate wax is mixed in conventional blender apparatus in a relatively short time period. The binder composition may also include a lubricity enhancer or slip agent and a dispersion or colloidal binder.
