Similarity and Difference on Making Techniques of U-Shape Jar Coffins in Yeongsan River Basin, Southwestern Korea by Quantitative Analysis

摘要

Background/Objectives: This study is to compare the differences and commonness between the affinities of making techniques through a quantitative analysis of jar coffins in the 5th to 6th century of Yeongsan river basin. Methods/Statistical Analysis: The only known as production site to Oryangdong have a variety of occurrences and making skills. There are composed mainly of quartz, alkali feldspar and biotite, which can be found in all jar coffins around the Najucentered consumption sites. Findings: Their firing temperature is divided into five groups, which widely vary at 700 to 1,200 ?°C. The consumption sites were rather high with 700 to 1,150? °C while Naju-centered area. Bannam and Yeongam area showed higher range of 1,050 to 1,150? °C in firing on jar coffins. Meanwhile, jar coffin tombs in the Yeongsan river basin don?ft have distinct local colors except main areas of Naju and each site shows various features. There are some differences in characteristics of jar coffin remains excavated from many tombs in the Yeongsan river basin if we look into them mainly with U-type jar coffins which are representative malformation of jar coffins excavated from production sites. Applications/Improvement: It is a little unreasonable to say that U-type large jar coffins produced in Oryangdong were widely distributed in the whole area of the Yeongsan river basin, and it is thought that they were distributed in some adjacent area.
