Owing to erratic firing behavior, the factors affecting finished sizes of ware were investigated. Uneven distribution of air and water content and uneven density produced irregular shrinkage and consequent cracking and warping. The percentage of water in the clay as pressed is shown to be the dominant factor as affecting shrinkage. Suitable loading of die corrected the differential shrinkage. Experimental procedure is detailed. Influence of rate of pressing on porosity is set forth.
