Interior view (left) and exterior view (right) of a partial pottery jar. The pot was found insitu near an anvil/grinding stone in an area interpreted by archaeologists as a metallurgical workshop. The jar' s everted rim is rounded (right, top). Its exterior surface (right, bottom) shows evidence of layering, with an upper layer of clay added to a leather-hard lower layer before the pot was fired. The pot' s walls are thicker than typical domestic pottery. Its find location suggests that it was probably made for an industrial rather than domestic purpose (possible pot bellow?). Dark smudging on the exterior surface affected both the upper and lower layers of clay, implying that it was exposed to high heat in a reducing atmosphere after manufacture. Striations on the vessel' s interior (left) are the result of smoothing and forming during manufacture, with a small area of post-manufacture smudging visible (upper left). The vessel' s ceramic fabric is tempered with laterite and crushed slag inclusions. It was found in close association with an anvil/grinding stone (GS 09-15), a circular iron disc (SF 09-370) and an irregularly shaped flat piece of iron (SF 09-371). Intact rim' s diameter (exterior lip): 13.5 cm. Photo scale in cm. Site Ngre Kataa. 4 July 2009.
