A plant and laboratory study was made of the use of frits as auxiliary fluxes in dinnerware bodies. The frits were addcd to a commercial earthenware body. Seven‐inch plates of thesc bodies were jiggered, fired, and glazed a t the pottery. Some practical difficulties encountered were as follows: (1) Due to the progressive solubility of the frits, even when this solubility was slight and only 2 to 4% of the frit was used, the slip was deflocculated and the plasticity of the body was destroyed. This trouble apparently was overcome by using a slight excess of hydrochloric acid in the body slip. (2) The ware of the bodies containing frit warped more than the normal body, especially in the glost fire. Results of tests of the slips, bodies, and ware are presented.
