项目摘要

Thirty four Vietnamese pottery sherds used in this study are unglazed, fired at good temperatures in the kilns and classified as stoneware. Those samples were collected from the old kiln sites and excavated at the archaeological sites both in the central Vietnam, and also excavated at different archaeological sites in Japan, Nagasaki, Sakai and Kyoto. l In this study energy-dispersive X-ray fluorescence analysis has been used for determination of 8 major elements in the bodies of samples such as Si, Ti, Al, Fe, Mg, Ca, Na and K. Almost al]. samples show irregular structures in appearances, then measurements were carried out 3 times at, 3mm diameter different portions in cross section of each sample for getting average composition. Micro-beam X-ray fluorescence analysis focusing 1.8 or 0.1mm diameter on targets was done for some of samples to know irregularities found in the parts of surface, inner and cross-section of them.X-ray diffraction analysis was carried out to identify the mineral compositions in these samples. Minerals found are quartz and mullite in the most of the samples showing they were fired at some higher temperatures in the kilns. The estimation of firing temperatures of this kind of pottery sherds can be tried by combination of mineral compositions and the results of differential thermal analysis (DTA). It is confirmed all samples were fired at good temperature conditions in the kilns.As a result of the cluster analysis of the element contents of the pottery sherds, almost all of samples found in Japan were identified as those from the kilns of the central Vietnam.

这项研究中使用的34架越南陶器棚是无上釉的，在窑炉的良好温度下发射，并被归类为stone器。这些样品是从旧的窑炉遗址收集的，并在越南中部的考古遗址进行了挖掘，并且在日本，长崎，萨凯和京都的不同考古遗址也进行了挖掘。在这项研究中，l使用了能量分散性X射线荧光分析，用于测定Si，Ti，Ti，Al，Fe，Mg，Mg，Ca，Ca，Na和K等样品体内的8个主要元素。几乎是Al]。样品在外观中显示出不规则的结构，然后在每个样品的横截面中直径为3mm的不同部分进行了3次测量，以获得平均组成。对某些样品进行了靶标的微束X射线荧光分析，以1.8或0.1mm的直径为目标，以了解在其表面，内部和横截面部分中发现的不规则性。进行X射线衍射分析以识别这些样品中的矿物质组成。在大多数样品中，发现的矿物是石英和mullite，表明它们是在窑中较高温度下发射的。可以通过矿物组成和差分热分析（DTA）的结果来尝试这种陶器饲养温度的发射温度的估计。证实所有样品均在窑中的良好温度条件下发射。作为对陶器植物元素含量的簇分析的结果，在日本发现的几乎所有样品都被确定为越南中部窑炉的样品。
