금속활자 주조를 위한 蜜蠟鑄造法의 鑄物土 실험연구

Abstract

Though the technology of casting movable metal types through lost-wax casting method has been theorized by previous researches, many tests and discussions have been continuously implemented for the purpose of identifying the soil of mold because of problems of its materials for experiments and mixture ratio.This study has an intention of identifying the kinds of proper natural materials, mixture ratio and physical characteristics for casting movable metal types through lost-wax casting method by experiment.To this end, the experiment was conducted with the following conditions and procedures, and the results of test were analyzed.1. Preparation for the Test1) Materials for making the mother letters : natural beeswax2) Casting materials : clay mixed with soft stones / mudstone, loess, sand3) Metal material : bronze, tin, lead2. Test procedure1) Carving the mother letters2) Casting the mold3) Melting the metal and making the types4) Trimming the types and Printing3. Analysis of the casting results1) Examination on casting materials2) Shape of movable metal types by materials3) Size variation of movable metal typesExperiments were conducted on casting the types with traditional casting materials to identify technology of casting movable metal types through the lost-wax casting. As a result, it was found that the problems of casting materials which have so far been much debated in the previous research were solved by using natural materials.Even though the test with natural materials was implemented successfully, lots of questions regarding the restoration process of casting metal types with the lost-wax casting method could be raised because how to cast metal types with the lost-wax casting method was not documented.For this, it is suggested that more research and tests for traditional casting method as well as the test for casting metal types should be conducted.
