On the study of restoration of pottery technology by natural scientific approachs.

在古陶器上，用考古学方法研究其产地的确定、原料粘土的选择和形制技术的鉴定，都不是很确定。本研究的目的，是以自然科学的方法来辨识与陶器制作有关的技术。目前还没有系统的方法来识别这些主体。在此，我们试图寻找更有效的方法，并在古陶工艺方面取得一些成果，作为今后这类研究的标准，我们注意到以下几点：1。对日本各地陶器产地的确定和各种陶器上原料粘土的鉴定，用岩石学方法对岩手县冰馆和中敷遗址的翁贺川型陶器，以及冈山立月遗址的礼器和壶架进行了分析。这些结果在“兵库县和梅之田第二遗址发掘报告”（1993年）和“弥生时代立月冢”（1992年）中有报道。本文用X射线荧光分析法对宫城县大仁寺古窑址窑壁和未熔瓦样品中的海水粘土和高温烧成的溶解陶泥的元素组成关系进行了分析。结果表明，窑壁样品中的S、Cl、Ca等元素含量与未熔窑瓦粘土样品中的含量存在差异.陶质粘土线团结构的重建。通过将甲基丙烯酸甲酯与荧光树脂混合填充到陶质中，并在紫外线下观察所制备的样品，可以更清楚地观察线团单元和线团之间存在的孔隙。

On the ancient pottery, it is not very certain to research for the determination of provinience, identification of selection of raw material clay and techniques of shape formation by the archaeological method. The object of this study is to identify of technology concerning pottery making by natural scientific approaches. There are not systemetic methods to identify these subjects now. Here, we try to find out more effective approaches, and get some results on the ancient pottery technology ; as the standard for future studies of this kind, we note following points for each analysis :1. Determination the pottery provinience in each parts of Japan and identification of raw material clay on a variety of pottery types.The Ongagawa type pottery from Hyogodate and Nakayashiki sites in Iwate prefecture, and ceremonial pots and pot stands from Tatetsuki site in on Okayama prefecture were analyzed by petrological method. These results were reported on "Report for Excavation of Hyogodate and Umenokidaich II Sites"(1993) and "Tatetsuki Mound of Yayoi Period"(1992).2. Relation bettween element constituents of the marin water clay and dissolved pottery paste by fired under high temperature.Samples of melted kiln wall and nonmelted roof tiles from Dairenji ancient kiln site in Miyagi prefecture were analyzed by X-ray fluorrescent method. As a result, there was difference in some element contents, for example, S, Cl, Ca, between the kiln wall sample and the nonmelted roof tile clay.3. Reconstuction of clay coils building of pottery.By the test of filling the methylmetaacrylate mixed with fluoresent resin in the pottery body and visualizing these prepared samples under ultraviolet ray, the unit of coils and pores of which exist between the coils can be examined more clearly.
