Abstract

The objective of this study is to identify the reason behind the expansion of exhaust holes and inhalational holes through high-definition filming and measurement of The Gilt-bronze Incense Burner of Baekje. In the proposed experiment, based on the original data obtained after a precise three-dimensional (3D) scan of the said incense burner, the precision replica and the commercial replica of the incense burner were subjected to a 3D scan. The overall shape and detailed patterns were subsequently compared with the original data. Furthermore, the incense-burning experiment was conducted according to the sizes and opened or unopened states of the exhaust and inhalational holes by employing the precision replica of the actual real relic for examining the internal structure of the lid and for studying the sizes and locations of the smoke holes. The results indicate that depending on the sizes of the exhaust and inhalational holes, the lower-line air intake holes can cause incomplete combustion in the incense burner. Depending on the opened or unopened states of the exhaust and inhalational holes, the phoenix air exhaust holes and upper-line air exhaust holes play a primary role in releasing the smoke, whereas the lower-line air intake holes play a primary role in smoke inhalation.

본고에서는 백제금동대향로의 고화질 촬영 및 실측을 통해 배연공과 흡기공의 확장이유를 밝히고자 하였다. 실험을 위해 백제금동대향로를 3차원 정밀 스캔한 뒤 스캔한 원본데이터를 기반으로 백제금동대향로 정밀재현품과 시판복제품을 3차원 스캔하여 전체적인 형태와 세부적인 문양을 원본데이터와 비교하였고, 뚜껑 내부구조 및 향연구멍의 크기와 위치가 실제유물과 가장 유사한 정밀재현품을 이용하여 배연공과 흡기공의 크기와 개폐유무에 따라 분향실험을 진행하였다. 분향실험 결과, 배연공과 흡기공의 크기에 따라서는 아랫줄 흡기공이 향로의 불완전 연소에 영향을 끼치는 것으로 확인되었으며, 배연공과 흡기공의 개폐유무에 따라선 봉황 배연공과 윗줄 배연공은 주로 연기를 배출하는 역할을 하며 아랫줄 흡기공은 주로 흡기구 역할을 한다는 것을 이번 실험을 통해 알 수 있었다.
