A study was made of the contraction of the Silver-Indium alloy due to the difference of the casting condition, by mean of the quartz pipe, whose thermal-expansion coefficient was very small. The results were as follows. 1) The higher the mold temperature, the smaller the casting shrinkage. 2) When the casting pressure was extremely low the casting shrinkage was great. But if the casting pressure was over 0.16 kg/cm2, the casting shrinkage didn't change. 3) The bigger the sprue size, the smaller the casting shrinkage. 4) The casting temperature of the alloy, the cooling system, the amount of the metal and the form of the wax pattern showed that the casting shrinkage remain the same.
