Most studies of ancient technology have hitherto been based on the civilisations of the Mediterranean and Middle East, especially those of Egypt, Greece and Rome. In this volume the extraordinarily well preserved remains at three major mining and metal production sites in the Aravalli Hills of Rajasthan (Agucha, Dariba and Zawar) were revealed. At these sites, by survey and archaeological excavation, the authors, studied the long-term development of mining and smelting activity over 3000 years. At Dariba and Agucha silver was mined by the Mauryan Empire on a colossal scale over 2,000 years ago. At Zawar the Mauryan mines seem to have produced mainly zinc oxide, but in the Medieval period zinc metal was produced by advanced processes of high temperature distillation, almost certainly the earliest commercial zinc production in the world. Here the laboratory processes described in the early Indian scientific works were developed into major industrial processes, the birth of chemical industry at least 500 years before similar developments began in Europe. The authors also analyse the decline and rebirth of extractive metallurgy in India.

This book presents a comprehensive overview of non-ferrous metallurgy, especially its core principles and fundamental aspects, in a concise form. The book covers all basic concepts and definitions related to metal extraction, and provide succinct summaries of relevant metallurgical processes. It also covers the scientific and engineering aspects of nuclear processes and features special chapter on ultra-high-purity metals. The book employs a step-by-step approach, is written in an easy-to-understand style, and discusses significance of core concepts. As such, it not only offers a valuable guide for professionals and researchers working in the areas of metallurgy, mining, and chemical engineering, but can also be used as a core text in both graduate and professional coursework.

This book provides a comprehensive introduction to the metallographic study of ancient metals. Metallography is important both conceptually as a microstructural science and in terms of its application to the study of ancient and historic metals. Metallography is a well-established methodology for the characterization of the microstructure of metals, which continues to be significant today in quality control and characterization of metallic properties. Not only does the metallographic examination of ancient metals present its own challenges in terms of sample size and interpretation of evidence, but it must be integrated with archaeological data and cultural research in order to obtain the most meaningful results. Issues of authentication and the establishment of fakes and forgeries of metallic artefacts often involve metallographic evidence of both metal and patina or corrosion interface, as an essential component of such a study. The present volume sets out the basic features of relevant metallic systems, enhanced with a series of examples of typical microstructural types, with illustrative case studies and examples throughout the text derived from studies undertaken by the two authors. This book provides a comprehensive presentation of metallography for archaeologists, archaeometallurgists, conservators, conservation scientists and metallurgists of modern materials.
