the present investigation is carried out to estimate the firing temperature and conditions of firing of ancient pottery shreds excavated recently from sembiankandiyur, tamil nadu, india. ftir and xrd studies have been attempted on these shreds to characterize the mineral composition of the pottery artifacts in respect of their different physical attributes. the firing temperature and conditions were inferred from the mineral phases of the samples exhibited by the infrared spectra and x-ray diffractograms recorded in as received state. tg-dta is the complementary technique to elucidate the firing temperature from the thermal characteristic reactions such as dehydration, decomposition and transformations of minerals under the controlled firing of the samples in inert atmosphere.
