This study aims to comprehend the transition patterns of various forms of red burnished pottery discovered throughout the Chungcheong and Jeonbuk provinces in the Middle Bronze Age and understand regionality through pottery style, paying particualr attention to the distinctiveness and universality of red burnished pottery. For this purpose, the Chungcheong and Jeonbuk provinces were further divided into the Asan Bay area, the west coast area, the area of the upper and middle reaches of the Geum River, the area of the middle and lower reaches of the Geum River, and the Mangyeong River area. To understand the transition patterns of each type over time, occurrence seriation was applied to each type and the order of arrangement was compared to archaeological features and artifacts. Radiocarbon dating was used to verify the temporal context of each type.
Each type of red burnished pottery developed in various ways in each regional unit, this presumably being related to the social-cultural changes that took place in the Middle Bronze Age. The decrease in the spread or exchange of resources and technologies in the Middle Bronze Age, accompanied by an increase in the number of kilns, is considered to have provided the foundations for more distinctive regional characteristics. These distinctive developmental aspects are considered to have affected the social use of red burnished pottery as burial goods. At the same time, this regionality was also accompanied by the sharing of technology for red burnished pottery, encompassing several regions. This reflects the commonality that existed among regions during the Middle Bronze Age. Differences in the use and type of red burnished pottery among regions can be interpreted as archaeological data reflecting the specific nature of the region.
