A combined analytical study of potsherds excavated from different archaeological sites of Tamilnadu (Kavalapatti, Nattapuraki and Thamaraikulam villages), India are analyzed by spectroscopic techniques such as FTIR, X-ray diffraction, thermogravimetric analysis (TGA) and Scanning Electron Microscope (SEM) coupled with Energy Dispersive Spectrometer (EDS). FTIR and XRD techniques have been attempted to characterize the mineralogical composition, firing temperature and firing conditions of the archaeological potsherds. Thermogravimetric analysis (TGA) is the complementary study to estimate the firing temperature from characteristic thermal reactions in potsherds under controlled firing in inert gas atmosphere. Further, Scanning Electron Microscopy (SEM) equipped and coupled with an Energy Dispersive Spectrometer (EDS) to analyze internal morphology and chemical composition of the potsherds was used. From the results of the above techniques, the firing temperatures of potsherds were found to be greater than 650°C.
对从印度泰米尔纳德邦不同考古遗址（卡瓦拉帕蒂、纳塔普拉基和塔马莱库勒姆村）出土的陶片进行了综合分析研究，采用了傅里叶变换红外光谱（FTIR）、X射线衍射、热重分析（TGA）和扫描电子显微镜（SEM）结合能谱仪（EDS）等光谱技术。已尝试用FTIR和XRD技术来表征考古陶片的矿物成分、烧制温度和烧制条件。热重分析（TGA）是一项补充研究，用于在惰性气体气氛中控制烧制条件下，根据陶片中特征热反应来估算烧制温度。此外，还使用了配备能谱仪（EDS）的扫描电子显微镜（SEM）来分析陶片的内部形态和化学成分。从上述技术的结果来看，陶片的烧制温度高于650°C。
