We report the spectroscopic investigation of ancient potteries excavated in Tamilnadu. Qualitative analyses were carried out to determine the major and minor constituent minerals present in the samples based on the band position or location of IR absorption peaks. From the prominent i.r. absorption peaks, the minerals were identified from the available literature. The constituents of minerals present in the potteries are further confirmed by XRD technique. Both FT-IR and XRD techniques reveals the mineral composition of ancient potteries. Energy dispersive X-ray fluorescence (XRF) was used to determine the major, minor and trace element composition of potsherds of ancient potteries. The concentration of trace elements is helpful for the characterization of pottery produced in a given region. The combined techniques are very much useful for the characterization of potteries.
