Glass pieces excavated from Mireuksa Temple dated 7th century A.D. were characterized by chemical composition, specific gravity and melting point. Lead isotope ratios of lead glasses were also compared with those of lead ore to attribute which lead ore was delivered for making lead glass. It was known that some lead glasses found in Japan were similar with those of Mireuksa Temple as comparing the data of chemical composition and lead isotope ratios. Characteristics of lead glass from Mireuksa Temple Thirty five glass pieces of Mireuksa Temple were analyzed for five oxides and found that all was lead glass system(PbO-SiO2) with the range of 70∼79% for PbO and 20∼28% for SiO2. The concentrations of oxides such as A l2O3, Fe2O3 and CuO were below 0.4%, 0.3% and 0.9%, respectively. Principal component analysis(PCA) as a statistical method was carried out to classify glasses with the similarities of chemical concentrations. The result of PCA has shown that three groups of glasses were created according to the excavation positions and two major oxides(PbO and SiO2) greatly contributed to the dispersion of glasses on principal component 1(PC1) axis and trace element oxides(Al2O3 and Fe2O3) for PC2 axis. Most of lead glasses were greenish by the efficacy of iron and copper oxides and some showed yellowish-green. The gravity of lead glasses was about 4.4∼5.4 and estimated melting point was near 670 ℃. Lead isotope ratios of glasses were analyzed and found quite close to a lead ore from the Bupyeong mine in Gyeonggi-do. Comparison with lead glasses found in Japan Lead glasses of Mireuksa Temple were compared with those of Japan on the basis of chemical and physical data. Chemical compositions of Japanese lead glasses dated 7th ∼8th century A.D. were nearly similar with those of Mireuksa Temple but lead isotope ratios of those were separated into two groups. Three distribution maps of lead ores of Korea, Japan and China with lead isotope ratios were applied for lead glasses found in Japan. The result have shown that the locations of lead glasses from Fukuoka Prefecture coincided with the region of northen part of Korea and similar with those of Mireuksa Temple and lead glasses from Nara Prefecture dated 8th century A.D. were located in the region of Japanese lead ore. This research has demonstrated that lead glasses of Mireuksa Temple conveyed to Miyajidake site, Fukuoka Prefecture around 7t h century A.D. and glass melting pots and glass beads excavated from Nara Prefecture confirmed the first use of Japanese lead ore for production of lead glasses from the end of 7th century A.D.

Thirty six samples of Western asia glass vessel shards which were excavated from South Mound of Hwangnamdaechong were each measured for thickness, pore size and specific gravity and analyzed for ten major compositions and thirteen trace elements. The glass samples with colorless, greenish blue and dark purple blue were well classified by principal component analysis(PCA). All glass shards of Hwangnamdaechong belonged to Soda glass system ($Na_2O-CaO-SiO_2$) which have the range of 14~17% $Na_2O$ and 5~6% CaO. The corelation coefficients of (MgO, $K_2O$) and (MnO, CuO) showed above 0.90. The concentrations of thirteen trace elements apparently differentiated from colorless, greenish blue and dark blue glasses. We found that thirteen trace elements were very important indices for studying raw material of glass and the origin of glass making. Colorless glass : The specific gravity is $1.50{\pm}0.04$. Circle or oval circle pores are observed with regular direction in internal zone and the longest one is about 0.35 mm. The raw material of sodium must be the plant ash because sodium glasses contain HCLA(High CaO, Low $Al_2O_3$) and HMK(high MgO, high $K_2O$) and suggested to Sasanian glass. The total amount of coloring agent of colorless glass is below 1 % which is too small to attribute to the color. Greenish blue glass : The specific gravity is $1.58{\pm}0.04$. The fine pores which are 0.1~0.2mm are dispersed in internal zone. Sodium glasses are distributed to HCLA and HMK. Therefore the greenish blue glass also have used plant ash for raw material of sodium with the same as colorless glass. It was also suggested to the glass of Sasanian. The total amount of coloring agent of greenish blue glass is about 4% under the influence of working MnO, $Fe_2O_3$ and CuO. Dark purple blue glass : The specific gravity is $1.48{\pm}0.19$. There are rarely pores in internal zone. They are distributed to HCLA and LMK(Low MgO, Low $K_2O$) and suggested to Roman glass. The raw material of sodium is estimated to natron. The total amount of coloring agents of greenish blue is about 3% by $Fe_2O_3$ and CuO. These studies for western asia glass shards from South Mound of Hwangnamdaechong could be used in the future as the standard data which could be compared with those of other several graves in Korea and dispersed in foreign areas.

전남 영광군 화평리 수동마을 움무덤에서 출토된 유리 시료 18점의 화학조성을 분석하기 위하여 주사전자현미경에 부착된 파장분산형 X-선 분석기를 사용하였다. 유리구슬의 색깔은 크게 녹청색, 감청색, 감색 및 투명한 것으로 나뉘었다. 각 시료에 대하여 10종의 산화물을 분석한 결과 투명유리를 제외하고는 모두 칼리계 유리로서 K2O 함략이 17.2~19.6% 범위였다. 투명유리는 다른 유리구슬에 비해 실리카 함량이 93~94%로서 높고 K2O 함량이 2~4%인 비결정성 물질임을 X-선 회절분석으로 확인하였다. 녹청색 유리는 구리가 착색원소로 착용한 것이며 감청색 및 감색은 미량의 코발트 성분이 착색원소로 작용한 것으로 추정되었다. 감청색과 감색의 차이를 성분 함량으로 살펴본 결과 감청색은 망간의 농도가 1% 이하이고 감색은 1.4~1.8%의 농도를 나타내었다. 이 분석결과는 전남 영광지역의 철기시대 유리제작기술을 알려주며 이러한 분석 사례가 쌓이면 시대별, 지역별 유리의 특성을 밝히는 연구도 가능할 것이다.

Sixty three potsherds from Chejudo island, Kurimji and Kungokni sites haven been analyzed by instrumental neutron activation analysis. Obtained data by INAA have been used to classify potsherds by multivariate analysis. The mathematical approaches employed are principal component analysis(PCA) and statistical linear discriminant analysis(SLDA). The plot of PCA has shown that the three distinct groups were created among potsherds of Chejudo island. Kurimji and Kungokni and some samples Irom Kungokni were includcd to Chejudo group. Seven trace elements such as Sm, K, La. Ce. Lu, Rb, Co were selected to be the main contributors for the classification of three groups by SLDA.
