N2  - Based on excavations, excavation documentation and archaeometallurgical analyses, this thesis aims to characterise Nok iron production in central Nigeria through a contextually based investigation. 
In 2010, 2011, 2013 and 2016, the Nok research project at Goethe University Frankfurt/Main in collaboration with the National Commission for Museums and Monuments, Nigeria excavated 27 iron-smelting furnaces from 8 sites 60 kilometres north of Abuja. All furnaces date around the middle of the first millennium BCE. Absolute dates, relative pottery chronology and terracotta figurine finds in furnace contexts suggest their affiliation to the Nok context. In comparison, all 27 furnaces resemble each other closely regarding their design and spacial arrangement. The numbers of furnaces per site, furnace width, furnace wall angle and thickness as well as pits beneath the furnaces are just some features with similar qualities. The similarities of the smelting sites also extend into their finds: the structure of tuyères and their position in situ as well as macroscopic slag morphology and distribution. Find morphology and distribution as well as furnace structure suggest a highly standardized way of Nok iron production. However, archaeometallurgical analyses show heterogeneous use of raw materials between sites and/or furnaces. In similarly structured furnaces different kinds of iron ore were smelted leaving a high iron content in the respective slags. This hints at an early stage of iron production in which the smelting process was limited to one operative set-up.
