Plastically moldable ceramic batch material, which may be flowably extruded under pressure into a self-supporting article of desired shape and configuration, is passed through a flow homogenizer positioned within an extrusion cylinder upstream of an article-forming extrusion die positioned on the discharge end of the extrusion cylinder, to thoroughly homogenize such batch material during the extrusion operation and prior to being fed through the article-forming die.
