ABSTRACT

This study attempted to trace the specific processes and principles of metal type wax casting method using Sanchung clay. (1) Matrix material: Injection wax was effective as the material. (2) Mould material: Sanchung clay was useful as the filling material. Paper fiber, oil carbon, graphite, and water carbon, among others, were useful as the functional materials. The mixture proportion was 1% for paper fiber, 5% each for oil carbon and graphite, and 5~50% for water carbon. (3) Metal components and the quantity and method of pouring: Bronze with 70% copper was effective. A small quantity of about 350 grams was poured using conventional method. (4) The number of character strokes: The number of character strokes had almost no impact on the success rate of casting. (5) The pouring direction of metal fluid: The pouring direction was the most critical factor in determining the success rate of casting ; that is, putting the character face in the lateral direction and pouring metal fluid in a standing mode. (6) The main path caliber for metal fluid: The size of 4.5×5.0mm was sufficient. (7) The temperature of mould: The degree of 600℃ was sufficient enough as the burning temperature for mould. The success rate was not affected by the mould temperature when pouring metal fluid. (8) The casting success rate and contraction rate: The highest success rate was 88.0%, and the overall success rate was 53.71%. The contraction rate was 2.45%. (9) The characteristics of type strokes: All the distinctive characteristics in 「Jikji」 were observed here. Therefore, it is highly likely that the wax casting method taken by this experiment is the same method actually used for casting Jikji types.
