ASTM C326 Drying and Firing Shrinkage of Ceramic Whiteware Clays
ASTM C326 measures the shrinkage of the ceramic whiteware after firing and drying the clay sample. This measurement enables the manufacturer to design the ceramic in the desired size and shape. The change in the thickness/shrinkage obtained by ASTM C326 is calculated to avoid any manufacturing defects. The shrinkage values are obtained in inch-pounds.
