Spectroscopic Analysis of Ancient Ceramic From Agror Valley Khyber Pakhtunkhwa, Pakistan

Abstract

\n The study of material remains has been very essential to reconstruct the past human lifestyle. Archaeologists use different scientific techniques to analyze the elemental composition of the material remains to locate the raw materials, to discover production sites and to understand ancient manufacturing technologies. Of these, Laser Induced Breakdown Spectroscopy (LIBS) method have been extensively used for the compositional analysis of different crystalline and non-crystalline materials of archaeological, historical and artistic interest for the last two decades. The present study was carried out to investigate the elemental composition of ceramic potsherds collected from the historic period. The present paper focuses on the major and minor elements identified through LIBS in the ceramic samples collected from different archaeological sites located in Mansehra, the easternmost district of Khyber Pakhtunkhwa Province of Pakistan. The LIBS results show the presence of Fe, Mg, Ca, and Na as major elements in the ancient ceramic along with traces of Si, Ti, Al and K. LIBS results show differences in the concentration of each elements present in every selected ceramic potsherds which indicates the source of raw material, production strategies and time periods of these objects were related to each other.
