In this study, the analysis of the characteristics of production techniques of the plain roof-tiles, a beating patterns in difference eras and examination of the changing process were performed based on the existing analysis and research done during the Kyoro Dynasty in Yeongsan river basin. In addition, the result of the analysis will help us verify the process of technical development as well as regional characteristics. This will further contribute to the first attempt to depict the general characteristics and differences in the field of roof-tiles research.
To do this, the present conditions of the Kyoro dynasty sites in Yeongsan river basin were identified first before subdividing the properties found in the excavated area. The result of the reviewing of these properties was as follows. The flat shape of the a convex roofing tile in non-tiered a convex roofing tile without upper raied spot for put on a convex roofing tile was changed to tiered a convex roofing tile with upper raied spot for put on a convex roofing tile. Also, it has ben identified that a beating patters changed from single pattern to two to three patters in a compound pattern. The production technique also changed from med-sized plate to a floor. Lateral separation method used outer side on one side and the other side used only inner separation method on the inner split.
Inner bottom adjustment was also found to have changed from either non-adjusted or shearing to manual water adjustment. Inner technique also experienced the changing process that can be seen in the inner title similar to the circular wooden case used as make roof tiles change in the horizontal hollow title. Based on these pattern changes and the production technique properties and a beating patterns centered around the analysis in the Koryo dynasty of Yeongsan river district the evidence and the time frame were measured.
The analysis of the excavated sites can be divided into three different stages. First stage, during the first half ninth century through first half tenth century. Second stage, mid tenth century through the first half twelfth century. Third stage, during the mid-twelfth and through chronological years.
The first stage characterizes the usage of the mid-sized a beating being standardized, but the floor a beating also started to emerge during this period. The inner bottom adjustment method used the non-adjustment and shearing adjustment. The flat shape of a convex roofing tile was found only as the non-tiered a convex roofing tile without upper raied spot for put on a convex roofing tile. The changing process of the separation method went through various separation methods such as both sides being the inner sides or one side the inner and the other the outer. In a concave roofing tile, the horizontal hollow which shapes the frame of the circular wooden dase used as make roof tiles was not found and the patter is mostly single door, following the traditions of Three Kingdoms period which maintained the lattice door and linear design. However, we see some changes into lattice design and avertical line design, as well as a phase of sophistication on the surface of a beating patterns. The a pattern of plumage shape started to appear after the eighth century in the form of a single door.
In the second stage, the length of the a beating plate and the usage of the mid-sized plated increased. For the inner bottom adjustment method, we see the appearance of the manual water adjustment and the flat shape tiered a convex roofing tile. The change in the separation method goes through the same phase as the previous stage, but the rate of the inner side is quite high and by the eleventh century, inner separation was standardized. In tiered a convex roofing tile, the horizontal hollow was found, but this predicts the change of the circular wooden dase used as make roof tiles. Also we see the limited patter that is unique in this period. a pattern of plumage shape together with the single door can be seen as compound doors in the form of flip vertical and vertical separation. The second stage, in coexistence with the first, is also known as a period in which the replacement of the new production technique took place as the previous one became extinct.
In the third stage, the production technique was standardized. The length of the a beating plate is only found as floor plate, and even the inner bottom adjustment method is only done through the manual water adjustment. The flat shape of a convex roofing tile coexists as non-tiered a convex roofing tile and tiered a convex roofing tile, but the rate of the tiered a convex roofing tile is higher and the separation method only uses inner separation method. In a concave roofing tile, the horizontal hollow is found as it is in the second stage. For the patterns, the rate of the single door decreases, and we see the change in the patterns centered around the a pattern of plumage shape. Moreover, either two to three patterns are combined or the rate of the geometrical patterns of the compound doors increases together with the a pattern of plumage shape, and by the fourteenth century, we see an appearance of the collective lines.
The shift of the plain roof-tile in difference eras reflect the significant changes in the society and archeological materials, however, the change of the tile is certainly in correlation with the change of the trade system .
