Abstract

In this study, glass beads from Osan Sucheong were classified according to color into 10 groups. Among these groups, reddish brown, bluish green, and purplish blue were identified as the main colors of glass beads based on their large quantities in Osan Sucheong. The glass beads of these main colors were then classified according to their chemical compositions and and looked at the changing process. Based on the results, reddish brown and bluish green glass beads can both be divided into five types, and purplish blue glass beads can be divided into four types. Furthermore, according to continuity of type, it was identified as the main attributes that the reddish brown beads belong to two types, whereas the bluish green and purplish blue each belong to one type. Based on a review of primary attributes, beads of these three colors were identified as soda glass and high-alumina glass. The results indicate that these beads came from a single, consistent route of origin into the region. However, it is possible that glass beads came through various routes into Osan Sucheong in the $4^{th}$ century, because many types of chemical compositions have been detected for beads from this time.

본 연구에서는 오산 수청동 유적에서 확인된 10가지 색상 중 다수를 차지하는 적갈색, 벽색, 감청색을 연구시료로 선정하여 화학 조성을 중심으로 각 색상별 유형을 분류하고 이에 따른 시기별 전개 양상을 살펴보았다. 유형 분류한 결과, 적갈색과 감청색은 5가지, 벽색은 4가지 유형으로 구분된다. 이를 출토 유구의 시기별로 살펴볼 때, 적갈색은 2가지, 벽색과 감청색은 1가지 유형이 시기의 연속성을 보여 각 색상의 주된 유형으로 판단된다. 주된 유형은 산화알루미늄($Al_2O_3$)의 안정제 함량이 높은 소다유리군인 공통적 특징을 보여 본 유적 조영집단은 지속적으로 유리구슬을 교역한 경로를 가지고 있었을 것으로 추정된다. 또한 오산 수청동 유적은 4세기 후엽 유구에서 다양한 유형이 확인되어 이전시기에 비하여 다양한 유통 경로를 통해 유리구슬이 유입되었을 가능성이 높다고 할 수 있다.
