Chemical and Microstructural Analysis of a Tin Coin of Sangam Period

An ancient coin from the Tamirabharani river bed was analysed for microstructure and chemical composition with an objective of understanding the nature of manufacture, and for corroborating information on the trade routes between Rome and South India. Advanced synchrotron X-ray and electron microsco...

More Information
Summary:An ancient coin from the Tamirabharani river bed was analysed for microstructure and chemical composition with an objective of understanding the nature of manufacture, and for corroborating information on the trade routes between Rome and South India. Advanced synchrotron X-ray and electron microscopy techniques were employed to evaluate the phases and their crystal structures, microstructure and chemistry. The study helped to identify the process route for the manufacture of the coin.
