보물 쌍자총통은 조선 중기에 사용하던 유통식 개인용 소용화기(小用火器)로 선조 16년(1583년)에 제작되었다. 이 연구는 동아대학교 석당박물관 소장 쌍자총통을 중심으로 제작기법에 대해 조사한 내용을 정리한 것이다. 쌍자총통은 전체 길이 53.3 cm, 구경 1.5 cm이다. 총구 2개가 연결된 몸통에는 6개의 약선혈이 있고 2개의 죽절이 관찰된다. 모병에는 사용법과 제작시기에 대한 명문이 새겨져 있다. 총구와 모병의 연결부에는 주조로 인한 어긋남이 있고, 측면에서는 주조 후 연마한 연마흔과 요철형 연결부도 관찰된다. 내부구조 조사 결과 쌍자총통의 내부의 주조기포가 확인되었고, 주물시 주물틀을 고정시키기 위해 사용하는 채플릿(chaplet)으로 보이는 6곳이 관찰되었다. 채플릿으로 확인되는 부분의 표면 분석결과 철(Fe) 수치가 높게 나타났다. 성분 분석 결과, 쌍자총통의 주성분은 구리(Cu)–주석(Sn)–납(Pb)을 주원료로 하는 3원계합금인 청동으로 판단된다.
Abstract
The Ssangja Chongtong Gun, manufactured in the 16th year of King Seonjo’s reign (1583), is a small tubular personal firearm used during the mid-Joseon Dynasty. This study investigated gun-manufacturing techniques focusing on the Ssangja Chongtong Gun owned by the Seokdang Museum of Dong-A University. The Ssangja Chongtong Gun is 53.3 cm in total length and 1.5 cm in diameter. There are six fuse holes and two rings, similar to bamboo nodes, on the double barrels. The handle is engraved with inscriptions describing the gun’s use and production period. There is misalignment between the barrel and handle of the gun that is due to casting; on the side, polishing marks and uneven joints formed after casting are observed. Research on its internal structure confirmed the presence of casting bubbles inside the Ssangja Chongtong Gun. Six parts that appear to be chaplets used to fix the casting mold during casting were also observed. Surface analysis of the parts identified as chaplets showed a high level of iron (Fe). Based on component analysis, the primary component of the Ssangja Chongtong Gun was determined to be bronze, a ternary alloy with copper (Cu), tin(Sn), and lead (Pb) as primary components.
