Major and trace elements and cross section textures of the large-sized jar-coffins excavated in the Young San river area have been analyzed for categorization according to geochemical characteristics of the raw materials. As results, we have found out that the jar-coffins of the Oryang-dong and Ungok-dong have very similar characteristics, and those of Songwol-dong and Jangdeung show distinguishable characteristics from the others. In addition, similar characteristics have been detected in some U-shape jar-coffins from several sites such as Oryang-dong, Ungok-dong, Sinchon-ri, Mansu-ri and Yeon-ri posess on trace elements and cross section texture. These results indicate that there was active physical migration although the detail route of the physical migration is unclear at current stage.

The burial custom in the Youngsan river area was to build a jar-coffin and lay the body in state, however the methods in building and moulding the massive jar, as well as in which kiln it was made has not been examined precisely. Thus, this research not only investigates previous results related to the manufacturing methods of massive jar-coffins, but also examines samples that were excavated and collected. The clay used to produce jar-coffin consists a large portion of unglazed qualities, which was split-moulded from the bottom up to the mouth area. The interior was finished by applying water, whereas the exterior was decorated by regularly pasting or stamping in parallel with a lattice design. It can be presumed that the finished jar-coffin was not moved, but the ceiling and walls were built around it as a kiln, for the jar-coffin to be oxidized or to reduce the flame condition in a temperature approximately $700~1,200^{\circ}C$The results from the research, however, show limitations to exploit the exact manufacturing method, therefore there is a need for in-depth examinations: mineralogical investigation on a large amount of jar-coffin samples through a polarized light microscope; substance analysis using various equipments; speculation on the temperature in the place of production and the flame inside.

이 논문은 국립나주박물관에서 진행했던 대형 옹관의 복원과 활용에 대해 고찰한 것이다. 처리 대상 소장품은 나주 복암리 3호분에서 출토된 것으로, 높이 194cm, 구연부 지름 108cm의 중량급 옹관이다. 복원 전에는 약 40여 개의 조각으로 분리된 상태였고, 복원 기간 동안 유물의 안전을 확보하기 위하여 전용 지지대를 제작했다. 복원 기간은 2018년 2월 5일부터 2월 27일까지 약 3주 간 보이는 옹관 수장고에서 진행했다. 이 기간 중 약 2주 동안 진행 과정을 관람객이 직접 볼 수 있도록 상설전시의 하나로 공개했다. 이를 통해 일반 관람객에게 '옹관'이라는 대형 유물과 이를 복원하는 작업에 대한 이해와 흥미를 유발하고자 했다. 또한 보존과학 업무홍보에 대한 국외사례를 조사하여, 보존과학센터 설립과 맞물린 홍보 방안을 고민해 보았다.
