  • The Mireuksaji stone pagoda is constructed Baekje Period in the 7th century which is located in Iksan, Korea. This stone pagoda designated by National Treasure No. 11 is the only remaining pagoda. This pagoda has lost the original form in part and the whole stonework wase dismantled. Work for the restoration is currently in progress. This study was divided into soil strata such as construct layer of the temple site, foundation layer of the pagoda basement, and construct layer of the stylobate by stratum to interpretation the skill of rammed earth and making techniques. The of physical, mineralogical and geochemical characteristics of soil samples were identified. Five pieces of soil in and around the Mireuksaji temple site was selected for the comparative study to interpretate the mutual homogeneity among soil stratum. As a result, artificial addition has not been identified in all soil samples using rammed earth. The soils used for the basement of the stone pagoda (construct layer of the temple site, foundation layer of the pagoda basement, construct layer of the stylobate) were confirmed to be the same origin as soil in and around Mireuksaji temple site. Thus these results indicate that the basement of the pagoda was constructed using soils in and around the Mireuksaji temple site without work as careful selection.

  • This research was to suggest the types according to structural system of the pagoda in ancient East-Asia and analyze the pagoda to the west of Mireuksaji temple site by these types. It will be possible to understand consistently the relation of the various form of the pagoda. The results of this research were described separately as follows. 1. The Buddhist pagodas founded in the ancient East Asia can be categorized according to their structural system, which provide us with insight to understand the interrelationship of categories. The pagoda is mainly classified into three categories. The first consists of two structures, an internal and an external structure. The second exposes its internal structure to the outside, and the third has the external components changing into the internal ones. 2. Although the pagoda to the west of Mireuksaji Temple Site have an internal and an external structures, it actually solves the structural problem by adopting the masonry structure in the outside as well as in the inside. Especially in this structural consideration can be found in the stylobate and the foundation structure of the pillar. The plan of the pagoda to the west of Mireuksaji Temple Site was intended to reveal the plane of the post-lintel layered construction which has a member, a main pillar, and the inner space in the cube with stones.

  • By analyzing the chemical compositions of bronze mirror presumably excavated from Mireuksaji temple site, Iksan, we have surveyed what alloy composition was used in casting the mirror, and also tried to estimate the manufacturing technique of the bronze mirror, through the observation of microstructure, as well as which region$^{\circ}{\emptyset}s$ galena the lead used in the mirror belonged to, by analyzing the ratio of the lead isotope. The content analysis result of bronze mirrors shows that it consists of 68.8 to 73.3wt% of Cu, 21.6 to 24.9wt% of Sn. In particular, the content of Pb of Mireuk 2 and 3 Samples are higher than those of Miruk 4. The observation result of microstructure demonstrates that Mireuk 2 and 3 consist of ${\alpha}$ and ${\alpha}+{\delta}$ eutectoide phase made through casting process. But Mireuk 4 show other process employed, such as quenching though martensite structure. In the analysis result of provenance though the lead isotope ratio, the origin of the used in bronze millers excavated from Mireuksaji temple site is presumed to be from galenas of Japen, like this those, the chemical competition, microstructure, and lead isotope ratio of bronze mirrors excavated from Mireuksaji can be utilized at fundamental data to compare mutually with other remains.

  • 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

  • Mireuksa Temple was founded during the reign of King Mu of Baekje(AD 600-641). The circumstance of the construction of this temple is documented in "Memorabilia of the Three Kingdoms (Samgukyusa)". The pagoda named stone pagoda at Mireuksaji temple stands outside the main sanctuary of the western area. The south and west sides of the stone pagoda have completely collapsed, leaving only the eastern facade of six of its levels intact. Through the recent discovery of sarira reliquary we can see that the erection of this pagoda was in 639. So owing to accumulation of excavation results about Baekje temple site and vigorous academic exchange, it is possible that architecture of western pagoda at Mireuksaji temple can be understood in connection with the architectural development of wooden pagoda from 6th to early 7th century in East Asia. So this study is on the consideration of building of this pagoda putting first structure of upper part and cross-shaped space in 1st floor. It was considered that the material characteristics as stone could be applied to the temple pagoda architecture of large scale. The results are as follows. First, it had been built in recognition that the outer and inner part of pagoda should be separated. As it is the expression of structural system in temple pagoda architecture of large scale at that time. In pagoda there was a self-erected structure and the members of outer part of it were constructed additionally. Second, in Mireuksaji stone pagoda there is central column with stones. With inner part of pagoda it can be regarded as mixed structural system that constitutes central contral column and inner structural part. And it could be a kind of middle step to more developed structure of whole as wooden pagodas in Japan. Third, as the sarira reliquary was in central column on the first floor, the cross-shaped space could be made. The formation of this space was so on the natural meaning of sarira that the concept as memorial service of graves could be apllied to the pagoda. The style of tomb in Baekje was expressed to the space of 1st floor in pagoda where Sarira had been mstalled. That was not only effective presentation of symbolic space but also easier method in the use of same material.

  • The Mireuksaji stone pagoda in Iksan is the largest stone pagoda existing in Eastern Asia. It was assumed that originally it had been established in the shape of nine-storied pagoda but as time went by only six-storied pagoda remained partially due to collapsing, repair and reconstruction. According to the reference, we can't make sure when its modification happened. The form that the pagoda is having now, was modified with concrete by the Japanese during the 1910s. The materials mixed in concrete were mixture of Portland cement, all sorts of stone, sand, and a little bit of new building stone, additive and compound. And also these materials were applied to cultural assets without any experiment at the time of 1910s as maintenance, which are still used recently. To prevent the change of its shape, the west side, south side and the north side which is partially destructed was rebuilt and reinforced with concrete and some of the deformed parts were also filled. The amounts of concrete used were about 200 tons. Such method had prevented the pagoda from destructing, however, by choosing a wrong repair method, its surface of the stone has secondary contaminants and precipitation caused by concrete. This kind of contamination speeds up the weathering which accelerates the aging mechanism of the stone to make it even harder to revive the absence of historical nature. Therefore, we are to find the best cleaning method to remove the secondary hazard contaminants.

  • The Mireuksaji stone pagoda of the Iksan was built in Muwang King of Baekjae Kingdom and has maintained its present status through several rebuilding process. Recently, the structural unbalance of the pagoda has worsened, so for scientific maintenance recovery of its original pagoda form, the pagoda is under dismantling process. The original form of this pagoda is being presumed to be a plane square pagoda of nine stories, though only a portion of six stories remains until today. The destroyed part from collapse was liked in insecure pagoda form by Japanese in year of 1915. On the surface of the stone which has gone through the present time, efflorescence appeared as precipitation substance over crusted and due to this phenomenon, the structure and color of thee original stone haven't been preserved. Therefore, quantitative analysis on its kind, emitted status and contamination type of secondary inorganic contamination substance of the over crusted surface were analyzed. Also through reaction experiments, contamination type was defined and tests have been applied to find the requirements that will wash out the contaminants. The result of this study will provide the base of quantitative analysis on the kind of inorganic contamination of the surface of stone assets, and it shall also contribute to the application of scientific maintenance recovery of surface cleaner for efflorescence.
