FT-IR spectroscopic analysis of archaeological pottery from Arikamedu, Puducherry, India

摘要

The present work deals with the FTIR spectroscopy study of the ancient pottery from excavated from Arikamedu, Puducherry, India. This technique is a power full tool for assessing both chemical and mineralogical composition of the archaeological materials. The firing methods and firing conditions of potsherds at the time of manufacture by a potter were inferred from the characteristic absorption peaks and the bands observed due to the presence of magnetite and hematite in the samples. FT-IR spectroscopic results revealed that archaeological samples were fired to a temperature greater than 800°C.
