This paper presents the results of elemental and lead isotopic analysis of copper alloys, copper-based pigments and an extremely rare tin-based alloy from the town of Amara West (Sudan), the centre for pharaonic control of occupied Upper Nubia between 1300 and 1070 BCE. It is the first assemblage of its kind to be analysed for Upper Nubia during this period. This research examines the selection and consumption of alloys in a colonial context, in light of earlier and contemporaneous practices and patterns in both Egypt and Nubia, to assess broader systems of resource management and metal production. Drawing on the complementary information obtained from pigment analysis, novel insights into interactions between different high-temperature crafts are obtained, particularly in terms of shared provisioning systems. From this unique perspective, pigment analysis is used for the first time to illuminate copper sources not reflected in metal assemblages, while scrap copper alloys are identified as a key colourant for Egyptian blue manufacture. The integrated application of strontium isotope analysis further highlights the potential for identifying links between glass, faience and Egyptian blue production systems within Egypt and for distinguishing these from other manufacturing regions such as Mesopotamia. The analysis of a tin artefact further expands our understanding of potential tin sources available during the New Kingdom and their role in shaping copper alloy compositions. Overall, this holistic approach to copper alloys and their application in other high-temperature industries ties together different strands of research, shaping a new understanding of New Kingdom technological practices, supply networks and material stocks circulating throughout the Nile Valley. • New Kingdom copper provisioning and alloying at a colonial settlement in Nubia. • Novel cross-craft approach to copper alloys, pigments and faience in the Nile Valley. • Integrated trace element and Pb & Sr isotopic analysis of Egyptian blue. • Rare tin-based artefact.
