A bstract Marked differences in shrinkage behavior and plastic deformations are caused by pressures commonly present in large shapes and in ware stacked during the drying period. Strains resulting from these variations may explain excessive cracking frequently encountered in large shapes and in the lower pieces in drier car settings. Plastic clays tested under the conditions of this test showed two yield values instead of one as was the ease with tests made with the Bingham plastometer. The tensile strength of a clay during drying was found to be a linear function of its water content.
