James Matthews excavation A second interim report

Les fouilles de James Matthews. Second rapport prelimhaire P. BAKER AND G. HENDERSON Les auteurs décrivent dans ce rapport les méthodes utiliées et les résultats obtenus en 1975–77, sur une épave coulée par faible fond sur la côte ouest d'Australie. Ils présentent, en détail, l'utilisation d'un carroyage rigide, facilement manoeuvrable et servant en même temps de plate-forme pour une tourelle - photo pyramidale. Les avantages et les limites de la photogrammétrie, pour les relevés subaquatiques, sont aussi exposés.     

The Archaeometry and Archaeology of Ancient Chinese Glass: a Review

This paper provides a new review of archaeometric research carried out on glass found in China, set in an archaeological context, from its earliest occurrence to the Song dynasty. It is set within a broad geographical context taking the terrestrial and maritime Silk Road contacts into account. We discuss chemical and isotopic compositional contrasts in glasses from different periods found in different parts of China, the glasses that were almost certainly made in China and those that were imported. A theme that runs through the paper is the problem of provenancing glass found in China, along with a lack of evidence for primary glass‐making sites and minimal evidence for secondary glass production. We discuss the glass artefacts that are of typical Chinese types and contrast these with imports; the structure reflects this contrast. We discuss potential new scientific and archaeological approaches to Chinese glass.
