This study investigates the earliest surviving Tibetan paper, from the Dunhuang cave library, using paper fibre analysis combined with codicological, palaeographical and textual information. The hypotheses tested by this method concern the regional origins and production centres of early Tibetan paper and methods for dating this material. Using overlapping typologies, we classify a sample of manuscripts into coherent groups, relating them to particular 'book cultures'. By linking three main manuscript groups to different geographical regions, we offer new insights into an important manuscript collection, and show that the method of overlapping typologies has the potential to yield further insights.

One hundred and sixty-nine fibre samples from books in the Korean collection and 68 samples from books in the Japanese collection at the British Library were analysed. A further 15 samples of Korean paper from a private collection were also examined. The analysis confirmed that most of the papers contained mulberry species (Moraceae family) as the main papermaking material, and other materials, such as hemp, rice straw and reed, which have been commonly known as supplements to traditional Korean papermaking. However, 15 Korean papers and one Japanese paper dating betweenad 1498 and 1798 appeared to include coniferous wood fibres. This substantial find supports a previous single find of a coniferous wood fibre in Korean paper. The dates of most of these papers containing wood fibres precede the use of wood pulps in European paper. [ABSTRACT FROM AUTHOR]

Tinning copper and copper alloy objects by putting them into (electrical) contact with metallic tin in a boiling aqueous solution of potassium hydrogen tartar is a very old technique, but is nowadays almost forgotten. It was possibly invented by the Gauls and used intensively until the 20th century. This paper first briefly recounts the history of this galvanic process. To understand better the parameters influencing the thickness of the coat and thus to reconstruct this ancient technique, laboratory tests were undertaken by varying a series of parameters. The results are then presented with a short interpretation. [ABSTRACT FROM AUTHOR]

This paper traces the events leading up to the formation of a project in 1954, in the Chemistry Department at Brookhaven National Laboratory, dedicated to the application of those new developments that were rapidly transforming postwar nuclear science to the parallel humanistic disciplines of archaeology and the fine arts. The further evolution of this effort involved the enlightened support of the Department of Energy (then AEC and ERDA) coupled with the lively interests of the archaeological, fine-arts and art-historical communities, their professional academics and the many graduate and undergraduate students who participated in the Brookhaven project. But more than new scientific methodologies, concepts and instrumentation were deployed. What developed was a large-scale, truly interdisciplinary effort, where scholars of the humanities and sciences worked side by side in a remarkable way, each led by the other, to the mutual benefit and increase of their knowledge and understanding. A paradigm of co-operation between arts and sciences was initiated: this paper presents a record of the process and its outcome, a novel blending of science and humanism that is very much taken for granted by research workers today.

Neutron activation analysis has been an important analytical technique for chemical characterization studies of archaeological materials since 1957, and remains one of the best analytical approaches for bulk chemical characterization of archaeological ceramics and other materials. This paper introduces a series of reports that document the history of NAA applied to archaeological materials. [ABSTRACT FROM AUTHOR]

In memoriam Tony ClarkSadly, this research marked the last field visit to the test site that the authors were able to share with their colleague Tony Clark. His enthusiasm, experience and encouragement inspired us to complete this project that, to many, must have appeared as grown men at play in a sand pit.A new approach to subsurface exploration has been developed, based on fixed-frequency radio-wave illumination from a buried transmitter. Data are collected from a buried, continuous wave source with a phase-coherent surface-scanning receiver and recorded in a digital archive from which images of the archaeological features are subsequently produced. An important feature of this approach is the opportunity to separate the data collection and archive functions, which form an uncompromised record of the site, from the more subjective image formation function. This paper reports the results of a feasibility assessment programme and discusses the future application of the method to real archaeological sites. [ABSTRACT FROM AUTHOR]
