Research Interests

Materials made or processed through pyrotechnology are an integral part of the last ten thousand years or so of human culture, and often form the majority of the material remains recovered from archaeological excavations. My interest lies in reconstructing and understanding of the processes used in the production of metals, glass and glazes, world-wide. Metal and glass artefacts are made typically through a combination of inexorable physico-chemical requirements (fixed laws of Nature), and organisational or behavioural aspects which are culture-specific and can therefore vary widely. Stripping out the fixed parameters in the technology gives access to the variable ones - revealing culture. I approach the interpretation of these materials and technological processes through data obtained by microscopic (optical and electron microscopy) and chemical analyses (by electron microprobe, X-ray fluorescence and other methods) of 'technical' finds, such as raw materials, intermediate and semi-finished artefacts, and waste products, where possible in conjunction with archaeological and historical textual sources. By identifying and defining the physico-chemical constraints I hope to isolate the culturally determined variables which can then be interpreted within a historically and theoretically informed research agenda. Current projects include work on glass and metal production in the Egyptian Late Bronze Age, the Iron Age to Classical Antiquity in SE Europe and the Mediterranean, and the Medieval Period in Europe and Central Asia.

Current Projects

The materials I am studying are drawn from a range of sources, including museum collections, surveys, rescue and research excavations. Currently, my primary involvement in archaeological fieldwork is the excavation of a Late Bronze Age (Ramesside) industrial and military complex in Qantir/Pi-Ramesse in the eastern Nile delta, directed by Dr. Edgar Pusch of the Pelizaeus-Museum Hildesheim. Since 1997, this has led to major new discoveries concerning the production of glass in New Kingdom Egypt, as reported in numerous papers and conference presentations, and a two-volume monograph following an AHRC-funded sabbatical in early 2007. The glass and faience-related research is still ongoing, and current work centres on the remains of the largest known pre-modern bronze casting installations, and the identification of lime kilns in Pharaonic Egypt.

Until recently, I co-directed several excavation seasons in Eastern Uzbekistan, focussing on the investigation of the early Islamic steel-making industry, and glass and glazed pottery production in and around Akhsiket, a major site in the Ferghana Valley. This project was undertaken in cooperation with Dr. Abdulhamid Anarbaev from the Institute of Archaeology, Uzbek Academy of Sciences, Tashkent, and funded by the Gerda Henkel Foundation.

Collections-based current research includes the study of urban metallurgy in SE Europe, in co-operation with the Institute of Archaeology with Museum, Bulgarian Academy of Sciences, in Sofia, the 13th Ephorate for Prehistoric and Classical Antiquities in Volos, Greece, and the Department of Archaeology, University of Belgrade. Of particular interest at the moment is the study of the earliest metal smelting documented so far, from c 5000 BC in Belovode, Serbia, and the development of arsenical copper as a major alloy into the Early Bronze Age, from Serbia through Turkey into Iran.

More recently, I have gone back to South American metallurgy in Peru and Chile, building on earlier work in Ecuador and Bolivia. In Peru, I have joined a team from UCLA to study pre-Colonial silver production in and around Puno, and in Chile I am working with Dr Blanca Maldonado, currently an Alexander von Humboldt-Fellow based in Mannheim, to study early copper smelting in northern Chile.

My involvement in Chinese archaeology began with a collaboration some years ago with Professor MEI Jianjun from the Institute for Historical Metals and Materials at the University of Science and Technology Beijing; at present, I am Visiting Professor there, co-supervising the doctoral research of CHEN Kunlong on early bronzes and LIN Yi-Xian on early glass in China. Yi-Xian is now a Newton International Fellow at the Institute, extending her resaerch into early glass and pigment use for ebads in NW China. A formal co-operation agreement of the UCL Institute of Archaeology with the Museum of the Terracotta Warriors and Horses of Emperor Qin Shihuang has led to an ongoing doctoral study of the composition of the metal implements of the army by one of their staff, Janice LI (supervised by Marcos Martinón-Torres). Due to this involvement in Chinese archaeology, I have been asked to be the Executive Director of the ICCHA.
