Abstract: The systematic and scientific study of artifacts reflects technological development and civilizations during the past. The importance of pottery artifacts as indicators of the artistic and technological advances reached by the ancient culture is investigatedby a number of techniques. Spectroscopic studies have been performed on recently excavated archaeological pottery samples from Thiruverkadu, Tamilnadu, India. The clay mineral type and its structural deformation due to firing have been studied from their Fourier transform infrared (FT-IR) spectra. The maximum firing temperature attained during baring, firing conditions (open/reduced atmosphere) and iron mineral phase changes is well established. X-ray diffraction (XRD) is used to identify minerals in the potsherds. Further scanning electron microscope (SEM) studies on potsherds pave the way to microstructural analysis and trace the subsequent development of virtification stages, thereby firing temperature is being confirmed. The results obtained from the different techniques provide the information for understanding the technological conditions implemented for the production of pottery and are found to give useful information about the analytical composition of potteries.
