New insights into the trade and processing of mineral raw materials for glass making This book presents a reconstruction of the Hellenistic-Roman glass industry from the point of view of raw material procurement. Within the ERC funded ARCHGLASS project, the authors of this work developed new geochemical techniques to provenance primary glass making. They investigated both production and consumer sites of glass, and identified suitable mineral resources for glass making through geological prospecting. Because the source of the raw materials used in the manufacturing of natron glass can be determined, new insights in the trade of this material are revealed. While eastern Mediterranean glass factories were active throughout the Hellenistic to early Islamic period, western Mediterranean and possibly Italian and North African sources also supplied the Mediterranean world with raw glass in early Roman times. By combining archaeological and scientific data, the authors develop new interdisciplinary techniques for an innovative archaeological interpretation of glass trade in the Hellenistic-Roman world, highlighting the development of glass as an economic material.

How an initially valueless object becomes worth hundreds of millions. And vice versa.The art world is a multi-billion-dollar industry which captures world headlines on a regular basis, for both good and bad reasons. This book deals with one of the most-discussed areas of controversy: high-profile objects that have experts arguing about their veracity. Some may have been looted, others may be fakes, some may be heavily restored or misattributed. Often, in these cases, analytical science is called on to settle a dispute. The authors of this book have decades of experience in this field, working on a range of objects dating from prehistory to the twentieth century. They present seven of the most famous cases from the Getty Kouros to the Turin Shroud – some of which are still contested, and examine how a few words from a connoisseur or scientist can make a virtually valueless object worth hundreds of millions. And vice versa.Read the introduction of the bookListen to an interview with Andrew Shortland and Patrick Degryse at New Books Network: https://newbooksnetwork.com/when-art-isnt-real

The historical and technological significance of cobalt and its compoundsCobalt: named after goblins, allotted to gods.Cobalt and its compounds have had a long and important part to play in history. Metallic cobalt is a modern innovation, vital in the green energy transition. However, cobalt compounds have been used for 3,500 years to create deep-blue pigments, featuring in many important works of art and religious artefacts, associated with heaven, eternity and the divine. Cobalt ores are rare, and their exploitation is a dangerous pursuit. Their co-occurrence with arsenic has led to severe health consequences for workers, which were blamed on supernatural spirits and goblins, “kobolds”, from which the name cobalt is derived. Of Goblins and Gods discusses the state-of-the-art of the extraction and use of cobalt ores through history, alongside the technology involved in making and applying cobalt pigments in many man-made materials across all regions and periods, from the Death Mask of Tutankhamun and pre-Islamic tiles to Indian manuscripts and the windows of Canterbury Cathedral.

Since 1990, the ancient city of Sagalassos in southwestern Turkey has been the focus of an interdisciplinary archaeological research project coordinated by the Katholieke Universiteit Leuven. The papers collected in this volume reveal how the meticulous systematic and interdisciplinary reconstruction of the ecology and economy of the site and its territory has enhanced our understanding of the ancient settlement and its inhabitants beyond the traditional aspects of classical archaeology in Asia Minor. Highlighting geo-archaeological, archaeometrical, and bio-archaeological work performed within the framework of excavations and surveys between 1996 and 2006, this important book's insights greatly enhance the promotion of real interdisciplinarity in classical archaeology.
