Thermal expansion (Table 2, 3, 4, 5 Fig, 1, 2), strength (Fig. 4, 5), transparency (Table 6. Fig. 3) and spalling resistance of porcelain teeth in K-feldspar-quartz, K-feldspar-sand, and in K-feldspar-quartz-kaolin systems were studied. The properties vane considerably according to the mixing ratios of raw materials, and a good result was obtained from the sample containing 60% of K-feldspar and 40% of quartz in quartz-K-feldspar system. The mixture of sand or kaolin and K-feldspar base did not give a satisfactory result.
