In this study, we analyzed the cross-sectional characteristics and chemical composition of glass bead fragments excavated from the 3rd and 4th excavation sites of the Daeseong-dong Tombs in Gimhae, South Korea. Consequently, comparisons were made with previously studied glass beads from the 6th and 10th excavation sites. We examined 45, 11, and 5 samples from wooden coffin, wooden chamber, and stone chamber tombs, respectively. The color purple-blue and drawing techniques were predominant among all samples, with casting techniques observed in the wooden chamber tombs. Based on a chemical analysis, 52 and 9 samples were categorized as potash and soda glass groups, respectively. The stabilizers included 45 type I potash, 7 high-alumina potash, 1 high-alumina soda, 2 low-alumina (Mineral) soda, and 6 lime (Natron) soda samples. Based on burial type, only the potash group was detected in the wooden coffin tombs whereas the soda group and casting techniques were observed in the wooden chamber tombs. Both the glass groups were present in the stone chamber tombs. Differences in the chemical composition and making techniques were observed across excavation periods. In the higher-elevation burial sites, the 6th excavation site predominantly featured the potash group and drawing technique whereas the 3rd and 10th excavations featured the soda glass group coupled with casting and winding techniques. Furthermore, the 4th excavation featured a drawing technique with diverse chemical compositions.

본 연구는 김해 대성동 고분군 3, 4차 발굴에서 출토된 유리구슬 편의 단면 특성과 화학 조성을 분석하고, 기존에 연구된 6차, 10차 출토 유리구슬과 비교하였다. 연구 대상은 목관묘 45점, 목곽묘 11점, 석곽묘 5점을 선정하였다. 분석 결과, 감청색 계통과 늘린기법이 주를 이루 며, 목곽묘에서 주조기법이 확인된다. 화학 조성은 포타쉬유리군 52점, 소다유리군 9점으로 구 분되며, 안정제는 포타쉬 Ⅰ형 45점, 포타쉬 고알루미나계 7점, 소다 고알루미나 1점, 소다 저알 루미나(광물성) 2점, 소다 라임계(네트론) 6점으로 분류된다. 묘제별로 목관묘는 포타쉬유리군 만 확인되며, 목곽묘는 소다유리군과 주조기법이 추가로 확인되고, 석곽묘는 포타쉬유리군과 소다유리군이 모두 나타난다. 발굴 시기에 따라 화학조성과 제작기법의 차이를 보인다. 구릉의 높은 지대로 올라갈수록 6차는 포타쉬유리군과 늘린기법, 3차, 10차는 소다유리군과 주조와 말은기법. 4차는 다양한 화학 조성과 늘린기법이 확인된다.
