A bstract Factors which cause variations in the finished size of clay products are determined. These are classified in the order of their importance, and limits are established within which the factors must be controlled to reduce these variations to a point which is consistent with the commercial production of modular products. The factors found to have the greatest effect on the finished size are soaking temperature and soaking time. Those factors having a lesser effect are (1) firing atmosphere, (2) relative amounts of clay mineral and quartz present in the clay in the different parts of the pit, (3) grain size of the clay produced by grinding or weathering, and (4) deairing treatment.
