Abstract :

The present work is aimed to investigate the ancient pottery from Alagapuri, Sivaganga District in Tamilnadu in order to study the materials used for firing, the technology of firing (either controller firing or open firing) and art of controlling the firing using spectroscopic techniques. The FT-IR and XRD spectrum are recorded in received state as well as re-fired state of the potsherds to study the thermal transformation of the minerals in determining the firing temperatures. The constituent of mineral present in the ancient potteries and also the estimation of firing temperatures are studied by FT-IR and XRD techniques. Further the TG-DTA was used to study thermal characterization of the samples. The combined methodology gives a complete spectrum for the estimation of firing temperatures of potsherds. Spectroscopic results revealed that ancient pottery was fired to a temperature greater than 750C.
