Sixty-four obsidian artifacts found in the Korean Peninsula have been characterised by a study of their minor elements and Sr isotope ratio. The artifacts are from the following locations: Yondaedo Island; Yokjido Island; Sangnodaedo Island, Tongyeong, Gyeongnam; Dongsamdong, Busan; Songdo Island, Yeosu, Jeonnam; Suyanggae, Danyang, Chungbuk; Sangmuyongri, Yanggu, Gangwondo; Paektusan Mountain; Kyushu region, Japan. The study of minor elements and Sr isotope ratio recognised three distinct major groups. This result suggests that there are no correlations among the three groups whose provenances are different. But as a result of classification using Sr isotope ratio, obsidian artifacts found in the southern part of the Korean Peninsula classified two groups within C group. This research will furnish scientific datum to be able to mutual comparison of obsidians excavated from other site.

Mireuk temple site is located in Iksan, on the North Jeolla province in Korea, and confirmed tiles, potteries, metals, glasses and other materials that are remaining between Baekje Kingdom and Joseon period after excavations. It is also detected that production and supply of the materials in this era were started inside the country(domestic) at that time. This is important information for the understanding of the production and circulation systems. In this study, lead isotope ratios of 18 samples includedlead glass, crucibles and glazed rafter tiles excavated from Mireuk Temple Site of Baekje era were analyzed for the provenance study of raw glass material supply and distribution of glass products. The results of lead isotope ratio analysis have shown that all raw materials were located in the distribution area of Baekje region and also confirmed to be accord with the previous research results. As comparing the lead isotope ratios of glass and glass materials excavated from Mireuk Temple Site with Miyajidake tomb from Fukuoka Prefecture in Japan, it is found that the same raw materials were used for glass production. It means that there is the active connection between Mireuk temple site and Miyajidake and that these areas are sharing the same materials at the same period. It also shown that artifacts excavated from Miyajidake were strongly influenced from Baekje culture. And it is estimated that there is a possibility of the use ofsame materials whether the supplies of them are from a specific place of Baekje or not

This paper tried a detailed approach to identify the correlation among basic elements that influenced the change of forms of the Po. To this end, the subjects were limited to the clothing from the 15th to the 18th century, which was found in the tombs of the period of Pyeonbokpo. The total number of excavated artifacts measured directly is 6 and other correctly described excavated artifacts for a total of 54 items. Per period and element, the types of collars and Seop were presented by classifying collars in 4 types, and Seop in 3 types. On the basis of the classification, the relics selected in this paper were analyzed considering the appearance, period, and rate per type of each element. The type and the change of forms of each element per period, with the focus on the appearance, were identified and the factors influencing the change of forms per element and the correlation between such factors were investigated. The representative type in the first period included dual collars, dual Seop and the representative type in the second period was characterized by a shawl collar and a dual Seop joining the pieces. The representative type in the third period was characterized by round collars and a short Seop. The elements determining the forms of Po, including collars and Seop, had a correlation to the lapse of time and had been systematically influencing each other. Furthermore, the overall change of form was caused due to the social functions as well as the supplementary function of keeping balance among the elements and accordingly, the change of forms was think characterized per period.

This paper confirms characteristics of lead isotopes of bronze artifacts excavated from Korea peninsula using 673 data classified according to Age, type and region. Lead isotopes data in Early iron ages are distributed in the southern Korean peninsula, but data in Joseon ages are concentrated in zone 3. Also Bronze artifacts excavated from Seoul, Gyeonggi, Chungcheong, Jeolla and Gyeonsang are manufactured using raw materials of the entire Korea peninsula, but bronzes excavated from North Korea aren't produced using raw materials of Gyeonsang provinces. Lead isotopes data will be able to find moving routes of raw materials and to separate the period of mixing and recycling of lead.

Archaeological investigations carried out in the Chilgok Housing Land Development Area have identified large-scale settlements from the Bronze Age and Three Kingdoms periods. The settlement site in Dongcheon-dong, Daegu was found to include sites of pit dwellings, buildings with elevated floors, stone coffin tombs, wells, catchment basins, stone mounds, furrows, cropland, moats, and river channels. These findings offer insight into diverse aspects of settlements during the Bronze Age. This study analyzed the species of trees that produced the materials for eight wooden artifacts excavated from a Bronze-Age river channel site. The analysis identified two examples of Pinus spp., two examples of Abies spp., and four examples of Quercus sp. The three artifacts of undetermined use were made using wood from Pinus spp. and Abies spp. Among the five artifacts identified as building components, one was made from Pinus spp. and four were made from Quercus sp.

The Sudang-ri Site in Geumsan is considered the historic site where Baekje dominated the inland traffic route to Gaya through Geumsan and Jinan in the 5th Century. This study identified the production techniques of iron by conducting an analysis of metallographical microstructure of the artifacts such as an iron sword and an iron sickle that were excavated in Sudang-ri Site, Geumsan, one of the regions ruled by Baekje, and tried to figure out the characteristics and the technical systems of Baekje's ironmaking around the 5th Century by comparing them with other iron artifacts produced around the same time. The analysis showed that various production techniques were applied to the artifacts excavated in Sudang-ri Site, Geumsan. Depending on the production techniques, they can be divided largely into three methods: the simple shape-forging method, the steel manufacture method after forging, and the steel manufacture & heat-treatment method after forging. The iron sickle from the stone chamber tomb No. 1, which was produced only through forging, is mostly composed of soft ferrite at both edges of the blade and at the rear making the use of the weapon impractical. From this fact, it is presumed that they were produced as burial objects or ceremonial accessories for the person buried. The iron axe from the outer stone coffin tomb No. 1 and the iron swords and sickle from the outer stone coffin tomb No. 12, which were produced through the steel manufacture method after forging such as carburizing, did not go through the heat treatment such as quenching, but applied different production processes to each part. Therefore, it is deemed that they were produced as daily tools for cultivation rather than burial objects or ceremonial accessories. The production techniques following the forging process - carburizing and heat treatment - can be found on the iron swords from the outer stone coffin tomb No. 5 and the outer stone coffin tomb No. 12. The sturdy structure of the blade part and the durable structure of the rear processed with heat are deemed to have been produced as weaponry and used by the person buried. Based on the analysis of the iron artifacts excavated from Sudang-ri Site in Geumsan, the characteristics of iron production techniques were investigated by comparing them with the artifacts from Yongwon-ri Site in Cheonan, Bongseon-ri Site in Seocheon, and Bujang-ri Site in Seosan that were made around the same time as the cluster of Baekje tombs examined by the metallographical microstructure analysis of this study. For the iron artifacts analyzed here, the changes in the techniques were investigated using the iron swords common in all of the tombs. In the case of the iron swords, it was identified the heat treatment technique called tempering was applied from the 4th Century.

Excavated archaeological iron artifacts are usually conducted the conservation treatment for removal of chloride ions in the corrosion products. However, some iron artifacts are corroded again even after the conservation treatment due to unremoved chloride ions. Therefore, it is important to prevent desalinized artifacts from the occurrence of corrosion after the treatment. In this paper, we investigated the characteristics of corrosion products on salinized iron artifacts and evaluated the variety of desalination methods such as autoclave, intensive washing and NaOH. It was also found that ${\beta}-FeOOH$ (Akaganeite) played an important role on the occurrence of corrosion and the treatment for removal of chloride ions. The extents of desalination were compared between the desalination methods. Results showed that the autoclave method represented the highest efficiency for desalination while the intensive washing method was the lowest.
