Metallography And Microstructure In Ancient And Historic Metals

David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.

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.

This is a review of 190 years of literature on copper and its alloys. It integrates information on pigments, corrosion and minerals, and discusses environmental conditions, conservation methods, ancient and historical technologies.

The sixteen essays in this volume reflect a wide range of research concerning methods for metals conservation, particularly in respect to ancient and historic objects. The variety of issues discussed includes considerations in the cleaning of ancient bronze vessels; the processes involved in bronze casting, finishing, patination, and corrosion; studies of manufacturing techniques of gold objects in ancient African and medieval European metalworking; techniques of mercury gilding in the 18th century; an investigation of patina in the classification of bronze surfaces from land and lake environments; an examination of bronze objects from the Benin Kingdom, Nigeria; the history of restoration of the Marcus Aurelius monument in Rome; the corrosion of iron in architecture; and applications of radiographic tomography to the study of metal objects.

The study of ancient metals in their social and cultural contexts has been a topic of considerable interest in archaeology and ancient history for decades, partly due to the modern dependence on technology and man-made materials. The formal study of Archaeometallurgy began in the 1970s-1980s, and has seen a recent growth in techniques, data, and theoretical movements. This comprehensive sourcebook on Archaeometallurgy provides an overview of earlier research as well as a review of modern techniques, written in an approachable way. Covering an extensive range of archaeological time-periods and regions, this volume will be a valuable resource for those studying archaeology worldwide. It provides a clear, straightforward look at the available methodologies, including: • Smelting processes • Slag analysis • Technical Ceramics • Archaeology of Mining and Field Survey • Ethnoarchaeology • Chemical Analysis and Provenance Studies • Conservation Studies With chapters focused on most geographic regions of Archaeometallurgical inquiry, researchers will find practical applications for metallurgical techniques in any area of their study. Ben Roberts is a specialist in the early metallurgy and later prehistoric archaeology of Europe. He was the Curator of the European Copper and Bronze Age collections at the British Museum between 2007 and 2012 and is now a Lecturer in Prehistoric Europe in the Departm ent of Archaeology at the Durham University, UK. Chris Thornton is a specialist in the ancient metallurgy of the Middle East, combining anthropological theory with archaeometrical analysis to understand the development and diffusion of metallurgical technologies throughout Eurasia. He is currently a Consulting Scholar of the University of Pennsylvania Museum, where he received his PhD in 2009, and the Lead Program Officer of research grants at the National Geographic Society.

This book provides a solid overview of the important metallurgical concepts related to the microstructures of irons and steels, and it provides detailed guidelines for the proper metallographic techniques used to reveal, capture, and understand microstructures. This book provides clearly written explanations of important concepts, and step-by-step instructions for equipment selection and use, microscopy techniques, specimen preparation, and etching. Dozens of concise and helpful “metallographic tips” are included in the chapters on laboratory practices and specimen preparation. The book features over 500 representative microstructures, with discussions of how the structures can be altered by heat treatment and other means. A handy index to these images is provided, so the book can also be used as an atlas of iron and steel microstructures.

Describes the metallography and microstructure of ancient metals with several case studies included. The first volume in this series is devoted to the alloys of copper with silver, lead, tin, zinc, antimony and arsenic.
