Abstract: A thin-walled honeycombed structure is made by extruding a plastically deformable batch, including ceramic materials mixed with water and a methyl cellulose extrusion aid, through a die apparatus comprising an extrusion barrel, an extrusion die extending transversely across the barrel and a mask located around the periphery of the outlet face of the die for inwardly moving peripheral portions of the extruded structure to form an integral skin of material. The temperature of the batch as it is placed into the barrel is 2*-25*F. (preferably 5*-15*F.) above the gel point of such batch. The extrusion barrel is maintained at a temperature 0*-15*F. (preferably 5*-12*F.) less than the temperature of the ceramic batch placed in the barrel (and preferably not less than 5*F. below the gel point of the batch) to form a uniform skin of desired thickness on the honeycombed structure.
