Spectroscopic and porosimetry studies to estimate the firing temperature of some archaeological pottery shreds from India

Assessment on the Characterization of Mineralogical Phase of Ceramic Tiles Available in Kathmandu Valley (Nepal) Using XRD and FTIR Analyses

“…On the other hand, there is a weak and very broad absorption peak in the range of 550-545 cm -1 in the tile samples indicated that the fired tile bodies available in Kathmandu valley contains a trace amounts of hematite. The similar result of the FTIR absorption peak at 540-550 cm -1 due to the presence of hematite in the fired ceramic bodies was reported in previous works also (Velraj et al, 2009a(Velraj et al, , 2009b.…”

FT-IR spectroscopic study of terra-cotta sarcophagi recently excavated in Ainos (Enez) Turkey

“…The shoulder around 914 cm À1 is assigned to Al-O-H libration vibration in the octahedral sheet. This band begins to decrease in intensity with increasing temperature [21,27]. Presence of this band indicates that the firing temperature of the CK-M23 should be less than the dehydroxylation temperatures of clays.…”

Application of various spectroscopic techniques to characterize the archaeological pottery excavated from Manaveli, Puducherry, India

“…The presence of bands 427, 591 and 1050 cm −1 are due to microcline, orthoclase at 465, 645 & 730 cm −1 and albite 725 cm −1 indicate feldspar group of minerals in the samples. The presence of absorption bands around 580 and 540& 476 cm -1 are due to magnetite and hematite, respectively, stated by Velraj et al [10]. The weak band at 3445 cm −1 is along with 1645 cm −1 due to OH stretching of hydroscopic water.…”
