In November 2011, various artifacts were excavated from the No. 8 stone-lined tomb in Suchon-ri, Gongju by the Chungnam Institute of History and Culture. These included artifacts with lacquered mainframe and silvery metal ornament. These were recovered together with soil and underwent conservation treatment. In this paper, we discuss the scientific analysis and conservation treatment of the lacquered artifacts excavated from the Suchon-ri site. Among our findings is that the artifacts have three layers of lacquer coating and the metal parts are primarily composed of Ag. As the artifacts were recovered with soil from the site, the soil was removed from underneath and inside the artifacts. The inside of the lacquerware was reinforced with rayon paper using 3% funori, and the metal was treated with acrylic resin after removing the acrylic resin previously used to recover the artifact, followed by cleaning. The metal was also internally reinforced with gauze. Finally, the interior reinforcement was made using PVA and resin in pulp and attached with funori to preserve the shape of the lacquerware, and the exposed rayon was finished with acrylic paint. The main advantages of this study are its review of conservation treatment strategies for lacquer artifacts whose numbers have recently increased, and the application of new conservation treatment methods.

마한과 백제유적에서 출토되는 철기는 철도, 철모, 철촉이 주를 이루고 있다. 철모의 경우 개인 병기라는 실용기의 특징이 있으며 환두대도의 경우 환두부분의 장식으로 인해 의장용으로써의 비실용기라는 특징이 있다. 공주 수촌리유적은 백제의 중앙과 지방의 묘제가 혼재하고 있는 유적으로 환두대도, 대도, 철모가 함께 출토되었다. 이들을 금속학적으로 분석하여 기능 및 제작기술에 대해 연구하였다. 위세품으로 추정되는 4세기 후반의 환두대도는 당시 최고 기술수준으로 여겨지는 담금질과 고체침탄의 제강기술을 이용하여 제작된 반면 같은 시기의 실용기인 철모에는 이러한 기술이 적용되지 않았다. 그러나 5세기에 이르러 실용기인 철모에도 담금질과 고체침탄기술이 적용된 것을 볼 수 있다. 이는 4세기 대 백제의 중앙은 우수한 철기 제작 기술을 보유하고 있던 것으로 볼 수 있으며, 지방세력도 이러한 기술을 보유하고 있었다 하더라도 다량 제작하여 무기로 활용하는 철모에는 이러한 기술을 적용하지 않은 것으로 판단된다. 따라서 사여품으로 추정되는 환두대도는 백제 중앙의 철기 제작기술체계가 적용되었으며 착장형 병기인 철모는 지방 세력의 기술체계가 적용되었을 가능성이 크다.

We have analyzed the ingredients of 17 pieces of Bronze Age bronze ware, and an additional 22 pieces of Koryo and Chosun dynasty bronze ware. We have also conducted analysis of the extraction sites where these bronze ware items were found. For analyzing the main ingredient the bronze ware items have been divided into 3 groups - Cu-Sn(70?75:20), Cu-Pb-Sn(70:10:10), Cu-Pb-Sn(60:10:20) type respectively. In tile cases of the Cu-Pb-Sn groups the division comes down to differences in the Cu content as the main component, and elements such as Ni, Fe, Co contribute as a micro ingredient. The geographical and periodic characteristics of ancient bronze ware items show that theircompositional element changes from Cu:Sn to Cu:Pb:Sn and the Cu content decreases with the period,while the Pb content increases with the period. Bronze ware items from Suchon Ri, Gongju (that were used in 3 B.C.) form very different categories from 3rd ${\~}$ 2nd B.C.. They additionally formed very different categories from those bronze ware items analyzed in this research. These bronze ware itemsare shown to be geographically close and periodically overlapped, but made of a new elemental composition. This shows an inflow of a production technical culture present in the new bronze wares. The main component content of Cu is lower, and the Co and Fe contents (as microelements) are much higher than that of other bronze ware items. Such facts showthat those bronze ware items used completely different materials from bronze ware items in other cultural areas, or that there were differences in smelting techniques In the places where ancient bronze ware items have been extracted, it is presumed that the materials originated from the southern parts of Korea andnorthern parts and southern parts of China. .As more bronze ware scientific research is compiled one can conclude that that there will be enough scientific evidence to study the Bronze Age culture of Koreasystematically.
