Recent archaeometallurgical investigations in Sudan have provided 97 radiocarbon dates which are used here to present a new chronology for ancient iron production associated with the Kingdom of Kush. Understandings of the formation, stratigraphy and dating of metallurgical waste deposits are used to demonstrate that iron production was practiced in the Meroe area for more than 1000 years, potentially starting as early as the 25th Dynasty period. Likely dates for the emergence and ending of iron smelting are considered in relation to political, economic and socio-cultural developments. The value and potential of this new chronology are explored, for example, in terms of insights into scale of production over time and resulting indications of organisation and management of this ancient technology.
