Abstract

This study revealed the material composition and characteristics of 19 glass fragments excavated from stone chamber No. 1 of Jeongchon Tomb in Naju through chemical composition analyses and observations. These characteristics were compared with the characteristics of the glass fragments excavated from No. 3 tomb of Bogam-ri in Naju. The purpose of this study was to identify the characteristics of the ancient glass of the Mahan-Baekje period. The glass fragments excavated from the Jeongchon Tombs can be classified into purplish blue, light-purplish blue, greenish blue, green, and mixture of purple blue and purple, based on their color. These beads were made using a drawn and casting technique. In addition, blue glass fragments were primarily excavated form No. 3 tomb of Bogam-ri. However, red glass fragments were not excavated from either of the tombs. According to chemical composition analyses, soda glass group and potash glass group were common in both the tombs. Additionally, alkali mixed glass group and lead barium glass group were excavated from Jeongchon Tombs and No. 3 tomb of Bogam-ri, respectively. The glass fragments excavated from No. 3 tomb of Bogam-ri have more color variations than those excavated from Jeongchon Tombs.

본 연구는 나주 정촌 고분군 1호 석실묘에서 출토된 유리구슬 편 19점에 대하여 형태적 특성 관찰과 화학 조성 분석을 통해 재질 및 특성을 밝히고, 이를 기초로 나주 복암리 3호분에서 출토된 유리구슬과 비교함으로써 마한 백제권에서 나타나는 고대 유리의 특성을 알아보고자 하였다. 정촌 고분군의 유리구슬은 감청색, 옅은 감청색, 벽색, 녹색, 감청색과 자색의 혼합색 등으로 구분할 수 있으며, 늘인 기법과 주조 기법을 사용하여 제작되었다. 복암리 3호분도 청색계 위주로 두 고분군에서는 모두 적색계 유리가 출토되지 않았다. 화학 조성에 따른 분류에서 정촌 고분군과 복암리 고분군에서는 공통적으로 소다유리군과 포타쉬유리군이 확인되었으며, 그 밖에 정촌 고분군에서는 알칼리혼합유리군, 복암리 고분군에서는 납바륨유리군이 확인되었다. 두 고분군의 유리 문화를 살펴보면 나주 정촌 고분군에 비하여 복암리 3호분이 색상별로 다양한 유형의 특성을 지녔다.
