On the provenance of stonepaste bodies of tiles from Takht-e Soleyman, northwestern Iran
A comparative compositional study of Egyptian glass from Amarna with regard to cobalt sources and other colourants
A selection of Late Bronze Age glass objects from the site of Amarna (Egypt) was analysed for their overall chemical composition, colourants and transition metals associated with the sources of cobalt ore. The objects were analysed by means of Particle Induced X-Ray and Gamma-ray Emission and Rutherford Backscattering Spectrometry at the IBC, HZDR, Dresden and the New AGLAE facility, C2RMF, Paris. The data was subsequently compared with further m…
Materials and technique of lajvardina ceramics from the thirteenth to fourteenth century Iran
Multi‐technical study of silver denars from medieval Poland for an improved understanding of their archaeological context and provenance
This paper discusses a methodology that involves the use of X‐ray fluorescence (XRF), high‐energy particle‐induced X‐ray emission (HE‐PIXE) and high‐energy particle‐induced γ‐ray emission (HE‐PIGE) spectroscopies for the study of historic denars with the aim of describing the advantages and limitations of each technique as well as arriving at an archaeometric interpretation of the compositions. A total of 39 medieval Polish denars minted by kings…
The use of Cobalt in 18th Dynasty Blue Glass from Amarna
Cobalt was commonly used as a colourant in the Egyptian glass industries of the 18th dynasty, dark blue glass being a regular find at palatial and settlement sites, including Amarna and Malqata. The main source of cobalt ore used during this period has been identified in the Egyptian western desert, around the oases of Kharga and Dakhla. In order to better understand the chaîne opératoire of Late Bronze Age glass production and -working, in parti…
Non-invasive scientific studies on the provenance and technology of early Islamic ceramics from Afrasiyab and Nishapur
Studying the process of enamel powder preparation for émail champlevé by colour measurements and μ‐X‐ray mappings
Colour measurements and non‐destructive μ‐X‐ray mappings have been used for the first time in a comprehensive study of medieval émail champlevé works from different production areas in France and Germany. This approach has given a new insight into the enamel powder preparation process of the glass material used for enamelling. Colour measurements demonstrated that all production centres used glass of very similar hues, but with large differences …
Product of the art market? The representation of silver corncobs at the Ethnologisches Museum in Berlin
In the 1960s two similar silver corncobs attributed to the Chimú-Inca period were sold by New York based art dealers to the Museum für Völkerkunde in Berlin, now the Ethnologisches Museum, and to the Denver Art Museum. The composition of the Berlin piece shows the use of different alloys, suggesting the reuse of different pre-Columbian objects. Only the hard-solders used to join the different parts of the corncobs contain an amount of zinc that m…
Dacian bracelets and Transylvanian gold
The recovery of the Dacian gold bracelets was the most thrilling archaeological event of the last years in Romania. The artefacts are exhibited in the Historical Treasure section of the National History museum of Romania, Bucharest, being recovered from the international antique markets through a concerted effort of the Romanian, French, and German authorities.This paper reviews the X-Ray Fluorescence (XRF) analyses carried out on these exquisite…
