The Ghana National Museum is exhibiting materials excavated from Nasia by Mustapha Kofi Mohammed in its renovated facility. The exhibition includes two tuyere pipes excavated by Mustapha during his Ph.D. fieldwork at the Nasia region, an ironworking hub in the Mamprugu region. Tuyere pipes are part of the superstructure of ironworking, serving as the channel through which air is taken into the furnace chamber in which iron ore stones are smelted to produce an iron bloom. The tuyeres are exhibited in the Iron Age section of the museum, where samples of tools and equipment produced by ironworkers to engender complexities during the period are displayed. Intensive Ironworking activities at the Nasia area is radiocarbon dated ca. 1300 AD - 1700 AD impacting significantly on social transformation in the region.
