“…The sample was probed at the same position of SEM-EDS using a signal detector of Si(Li) with 6.2 mm in diameter and 3 mm thick (Model SL30170, Canberra Industries Inc., Connecticut, USA). Silicon with known concentration was used as a standard reference for PIXE analysis as conducted in previous research [27][28][29][30][31][32][33]. Quantitative analysis of chemical composition (for Z ≥ 13) was performed using GUPIXWIN code (GUPIX software for Windows version, Department of Physics, University of Guelph, Ontario, Canada) [34][35][36].…”

Ancient potteries found at Ban Muang Bua, located in northeastern Thailand, associate with Thung Kula Ronghai culture. Most of them are products used in daily life and grave goods. The potsherds were examined using techniques based on X-ray spectroscopy. Elemental composition and morphology were analyzed using proton-induced X-ray emission spectroscopy (PIXE) and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS). Three-dimensional analysis was performed using X-ray tomographic microscopy based on synchrotron radiation (SR XTM). Irregular plate-like particles of composites with a wide range of size distribution were found in the potsherds. The major (O, Si, and Al), minor (C, Fe, Ca, and K), and trace elements (P, S, Ti, Na, Mg, and Zn) which were observed can provide the information about raw materials and production of pottery. The 3D tomographic images show the internal feature of these samples. The combination of SEM-EDS, PIXE, and SR XTM is a powerful tool for archaeological research especially in terms of composition and internal structure. The results imply that the raw materials of pottery were sandy soil derived from marine sands, clays, and salt deposits that were mostly iron-rich-kaolin clay. The production was carried out with low firing temperatures (~600–900 °C) in open-air kilns.

The five thousand years of Chinese culture has congealed countless crystallization of wisdom, and glass is also one of the products. However, because in ancient times the technology of the China glass production failed to reach the current level, it is highly susceptible to be weathered by the burial environment. The paper provides theoretical support for the archaeological study of ancient glass by correlating the relationship between surface weathering and the features of glass artifacts and by exploring the classification rules of ancient glass of known glass varieties (lead-barium glass and high-potassium glass). For the relationship between color and surface weathering, the most suitable AHP model is selected in the paper, while the importance scale of AHP is quantified by combining the physical model. Secondly, the Kendall coefficient consistency test model was used to analyze the correlation between glass varieties and surface weathering. Finally,the chi-square test model was used to analyze the correlation between ornament and surface weathering. The paper draws a conclusion that the surface weathering of glass relics has more correlation with its color, the deeper the color, the greater the possibility of surface weathering; the correlation between lead-barium and weathering is high; and the degree of correlation between glass ornamentation and weathering is very low in agreement.In view of the classification problem, the paper uses linear discriminant analysis (LDA) to establish a linear classifier and quantify the classification rule, in order that data with low frequency are not reduced, so as not to truly reflect the classification law, and finally the paper obtains a linear classifier with accurate classification.
