Hardcover. Zustand: New. Contents: Foreword. Preface. 1. Microstructural studies of composite Mughal period cannons of Daulatabad Fort, India by electron backscattered diffraction and scanning electron microscope. 2. Examination and analysis of Indian silver punch-marked coins employing WD-XRF and other non-invasive techniques. 3. Medieval silver coins of India: composition and authentication. 4. Analysis of Kushan coins (1st-3rd century CE) by Multi-spectroscopic techniques. 5. Chemical analysis of lead coins of the Ikshwaku period (3rd-4th century AD). 6. Scientific examination and analysis of some ancient coins. 7. Method for stabilization of leaded bronzes affected by corrosion of lead. 8. Poly [bis (benzotriazolato) di-u-oxa-dilead (II)]: a new corrosion inhibitor for the highly leaded object. 9. Technical studies of copper coins from Pirvitani Sarif Bahraich U.P. India. 10. The authenticity of copper coins from Kushan period. 11. A study of environmental acidification on copper: their detoriation and protection. 12. Identification of fake gold coins by micro XRF system.l 13. Corrosion and corrosion control of copper by nBTA in storage and the atmospheric environment by electrochemical technique. 14. Lead in various environments: their corrosion and mitigation. The book exclusively deals about the various advance instrumental techniques applied for the examination of historic Indian coins for their composition and microstructure. Based on the author s more than 37 years of experience in the field of metal conservation, the book highlights the type and source of minerals for minting the coins, fabrication technology and discrimination between the fake and old coins based on scientific examinations. Few newer methods for the preservation of ancient coins, leaded bronzes, and metal artifacts have been highlighted based on field trial. The book also incorporates about the cannon metal and fabrication technology used for bimetallic medieval cannons using advanced instrumental techniques like Electron Back Scattered Diffraction (EBSD) and Scanning Electron Microscope (SEM). The authors have compiled all their international and national publications for this book project for the benefit of researchers, metal conservators and scientific institutions working in the field of metals and alloys.
