  • This study is aimed to investigate the provenance of raw materials and firing temperature of jar coffins excavated from the Oryang-dong kiln site and Jeonchon tomb site, Naju, Korea. Most of jar coffin samples shows same range of magnetic susceptibility and have gray color, while 404 and 405 of Jeongchon site are reddish yellow. In some samples fired at high temperature, the water absorption at the mouth rim and body part of same jar coffin were 3.50% and 7.56% respectively. It means that heat transfer and equilibrium in the kiln was not properly continued and the heat energy transferred to the mouth rim and the body part was different. In the petrographic analysis, As a tempering materials, biotite, weathered quartz and feldspar were added in the jar coffins of Oryang-dong site, and biotite, polycrystalline quartz and feldspar in it of Jeongchon site. Tempering materials were found more in the body than in the mouth rim of same jar coffin of Oryang-dong site. It seemed that some samples were fired at over 1,000 to $1,100^{\circ}C$, which showed vitrified texture in the scanning electron images and the rest of samples were fired at below $900^{\circ}C$. Due to similarity of chemical compositions, it is estimated that jar coffins of Jeongchon tomb were produced and supplied from Oryang-dong kiln site. However, the slight difference of some trace elements distribution of samples is attributed to the selection of clay depending on the location.

  • The 5th century kiln that produced pottery coffins was found for the first time in Korea, located in the Oryang-dong remains in the city of Naju. This kiln, located in the central area of the Yeongsan River, provides important data for research on mortuary practices in prehistoric society, including the structure of production and patterns of distribution and consumption. For this study, the remains of five ancient tombs and pottery coffins excavated from the 4th century Mandong archaeological site were chosen to determine the area of consumption of pottery coffins produced at the Oryang-dong kiln. The samples from each area of remains were analyzed for minor elements using neutron activation analysis method, and from these results, the identities of the corresponding production areas were investigated using the multi-variant statistical analysis of discriminant analysis. The evidence strongly suggests that pottery coffins produced at the Oryang-dong kiln in Naju were used in ancient tombs of the Bannam mound in Naju, the Okyari mound in Yeongam, and the Banam mound in Hampyeong, reaching those sites through trade and distribution. The findings also suggest that pottery coffins from the Mandong archeological site in Gochang and the Inpyeong mound in Muan were not produced at the Oryang-dong kiln in Naju, but rather were brought from pottery kilns in different production areas, through trade and distribution.

  • Large Jar had been manufactured and used broadly in Mahan area from late second century. At first, it was used for various purposes, for example storing utensils at household and religious service at tombs. But it's usage was shifted with the political expansion of Baekje. In late third century, large jar coffin appeared in tombs as an important burial unit at Yeongsangang river valley. It has specific traits such as saw blade-shaped design etc. That style is distinguished from Baekje's. Unification of form and style of large jar coffin signify the socio-political distinction between Yeongsangang river valley and Baekje. Large jar coffin was used emblemic style for this purposes by the political elites of the Yeongsangang river valley. This process was caused by political reason, that is, need for integration of the Yeongsangang river valley communities against the territorial expansion of Baekje state.

  • The objective of this study is to find out geomorphological characteristics of historical ruins where people produced and consumed large jar coffins excavated in the Yeongsan river basin using Fluvio-Marine Plains from detailed soil map. For this purpose, we chose the 21 consumption sites. The results are as follows. 21 consumption sites located in the region of upper limit of tidal internal in Yongsan River and tributary rivers. Among these, 18 Consumption sites has high accessibility with Fluvio-marine plains. This means that Consumption remains of Yongsan River basin have been located to area available for distribution from production sites.

Interpretation of Material Homogenity and Making Techniques of the Jar Coffins from the Oryangdong Kiln Site and the Ungokdong Tomb Site in Naju, Korea (나주 오량동 가마와 운곡동 분묘 유적 출토 대형전용옹관의 재료학적 동질성과 제작기법 해석)

  • The pupose of this study was to identify the material characteristics, firing environments and making techniques for the jar coffins from the Oryangdong kiln site and the Ungokdong tomb site in Naju. All jar coffins had very similar physical, mineralogical and geochemical characteristics, although it was excavated from the different sites. The wall thickness of the jar coffins was about 2.3 to 5.3 cm. Under the microscopy, the jar coffins include a large quantity of various quartz with some microcrystalline and showed partly orthoclase and biotite. It is presumed that the mineral sherds added to maintain the thick wall and to control the percentage of contraction during drying and firing of jar coffins and it has contained about 11.4 to 19.8 %. Firing temperature of the jar coffins is estimated as 1,000 to $1,150^{\circ}C$. Also, all jar coffins and soils show similar geochemical behavior of elements and clay-mineralization degree within the site. This indicates making that the soil is probable to be a raw material of the jar coffins. But it shows different characteristics in major elements of soils which is collected at the kiln floor and the trench region of the Oryangdong kiln site because of the lack of quartz and feldspar in the soils. Therefore, it can use of the jar coffins making clay, if it goes through a simple special process such as mixing temper.

  • The purpose of this study is to apply one of the geophysical methods, GPR to archaeology. Time slice of analysis method was used to interpret archaeological feature before excavation. Study areas are Pubcheonri burial mound group in Wonju, Songhakdong no. 1 tomb, Gosung in Kyungsangnamdo, and Yoshinogari 2 rows of jar-coffins burial in Saga Prefecture, Japan. We found a stone tomb, spreaded and piled stones from spoiled tombs of the Baekje Dynasty as archaeological features in Pubchonri, Wonju. Songhakdong no. 1 tomb in Gosung was the unique keyhole-shaped tomb in Kyungsangnamdo as we know. But we found that the tomb consists of 3 tombs and there are lots of stone tombs according to the GPR and excavation. From the GPR exploration and excavation, it turned out not be a keyhole-shape tomb. We also found jar-coffins burial in Yoshinogari, Japan. As a result GPR was very helpful to detect archaeological features and pattern before excavation in advance.
