Abstract

This study is to be investigated through component analysis and metallurgical texture in order to save an information of the manufacturing technique for the bronze bell in Naksan-sa. The bronze bell was analyzed with nine samples not stirred by the fire and except the contents of tin is the maximum and minimum the average of Cu is 81.8wt%, Sn is15.8wt% and indicates that some impurities are in it. With the result of an analysis of component and microtexture for impurities material which exists in it with using the SEM-EDS, the material was revealed the sulfur. As the result of these factors, the bronze bell of Naksan-sa is used from ore which mainly consist of the Chalcopyrite($CuFeS_2$) or Bornite($Cu_5FeS_4$) containing much sulfur.
