MathRepo is a repository of the Max Planck Institute for Mathematics in the Sciences in Leipzig, dedicated to mathematical research data. Research data are all digital objects that arise during the process of doing research or are a result thereof. In particular, the purpose of this repository is to collect scripts and code, to explain applications of mathematical software, to showcase additional examples to paper publications, and more generally to host supplementary material developed for research projects or discussed in workshops.

The Research Data Centre (Forschungsdatenzentrum, FDZ) at the Institute for Educational Quality Improvement (Institut zur Qualitätsentwicklung im Bildungswesen, IQB) archives and documents data sets resulting from national and international assessment studies (such as DESI, PIRLS, PISA, IQB-Bildungstrends). Moreover, the FDZ makes these data sets available for re- and secondary analysis. Members of the scientific community can apply for access to the data sets archived at the FDZ.

Portable X-Ray fluorescence analysis of Late Bronze Age glass from Amarna

KBLT

Subject(s)
Country
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. The data presented here was obtained in order to better understand the chaîne opératoire of Late Bronze Age glass production and -working, in particular with regard to cobalt ore. For this purpose, chemical analysis by portable X-Ray fluorescence (pXRF) was carried out in the field on contextualised archaeological material excavated at the site of Amarna, which cannot be exported from Egypt for analysis. In addition, glass and other vitreous materials from the same site, but without a more precise archaeological context, were analysed in the Egyptian Museum and Papyrus Collection, Berlin. The results of this study demonstrate how cobalt ore from various sub-sources was used in the known workshop sites at Amarna, resulting in a deeper understanding of raw materials use and exchange across this settlemen
