Reconstructing Field-firing techniques of Jomon and Yayoi pottery and Hajiki ware pottery.

这项研究的目的是建立从生态功能角度分析陶器的方法，关注功能效率、耐用性和成本之间的平衡。我们的研究方法的独特之处在于：(1)详细观察考古陶器中发现的烧制痕迹，(2)旨在帮助解释考古陶器中发现的各种模式的一系列野外烧制实验，(3)系统地比较研究稻农的民族田野烧制技术，本研究的另一个特点是举办了一系列研讨会，向对这类课题感兴趣的考古学家介绍上述研究方法和射击痕迹分析的诀窍。在两年任期内共举办了8次讲习班。幸运的是，一些考古学家对我们的研究方法产生了兴趣，并在研修班结束后参与了分析和撰写报告。首先，关于弥生时期初期朝鲜半岛开始的隐蔽射击，很明显，日本西部的第一个弥合人接受了与韩国几乎相同的隐蔽射击技术，因为消耗了较多的柴火，稻草盖不是很紧。然而，在日本西部稻作农业发展的过程中，最初的遮盖射击逐渐转变为覆盖范围更紧、耗油量更少的遮盖射击，表现出与韩国遮盖射击更明显的区别。

The purpose of this research is to establish the method to analyze pots from an ecological- functional viewpoint, focusing on the balance between functional efficiency, durability and cost.Our research method is unique in that it consists of (1)detailed observation of firing traces found in archaeological ceramics, (2)a series of field firing experiments which are designed to help interpret various patterns found in archaeological pots, and (3)systematic comparative studies of paddy-rice farmers' ethnographic field firing techniques, which enables us to demonstrate fundamental structure and variations of covered-firing techniques.Another characteristic of the present study is a series of workshop were held in order to introduce the above research methods and know-how of firing-trace analysis to archaeologists who are interested in this kind of topics. A total of 8 workshops were held during the 2 years term. Fortunately, some archaeologists got interested in our research method, and took part in analyzing and writing reports after the workshops.As a result of these workshop research, the following points have been demonstrated. First, concerning the inception of the covered firing from the Korean Peninsula at the beginning of Yayoi period, it became clear that the first Yayoi people in western Japan accepted the covered firing technique which was almost same as that of Korea in that relatively large amount of firewood were consumed, and the rice-straw cover was not very tight. However, in the course of the development of paddy-rice farming in western Japan, the original covered firing gradually changed into a less-fuel consuming ones with tighter coverage, showing more distinctive differences from Korean covered-firing.
