Abstract

The aim of this paper is to assess the full potentialities of spectroscopy techniques in the art work investigation and to explore the capabilities in the determination of the chemical and mineralogical composition of ancient pottery excavated from Kottapalayam village, Karur district, Tamilnadu. Spectroscopic techniques such as FT-IR. X-ray diffraction, thermal gravimetric analysis and scanning electron microcopy (SEM) coupled with energy dispersive X-ray spectrometer (EDX) are utilized in this work. The constituent of the minerals is identified with help of FTIR and compared with XRD. The combined mineralogical results showed that the pottery samples from Kottapalayam were fired in between 800ºC-850ºC. The microstructure and elemental composition of the pottery sample were evaluated from their microphotograph by Scanning Electron Microscope (SEM) along with energy dispersive X-ray spectrometer (EDX). The results are discussed and the conclusion is drawn.
