- Description:
- Several grinding stones, a whole pot and a cluster of pottery sherds have been exposed in situ at the base of level 3, unit 44N 4W at Mound 6, Ngre Kataa. The large grinding stone in the foreground (grinding stone 1, NK-08-112) is oriented with its grinding surface facing down. Another smaller stone rests on a soil pedestal created as archaeologists excavated surrounding soil to a lower level. Upper right, a whole pottery jar (NK-08-176) sits next to a large grinding stone (grinding stone 3, NK-08-173) oriented with its grinding surface up. To the far left, above the photo scale in centimeters, archaeologists have exposed the edges of a pottery jar, broken in half and lying on its side. As excavations extended into the adjacent unit (42N 4W, to the left), this broken pot was found to be associated with two tuyere fragments. This cluster of grindstones, tuyeres and nearby burned features is interpreted as part of a larger metal-working workshop, the activities of which led to the build up of mound 6. The soil on the right side of the unit is darker because it is moister than that on the left. View to west. Site Ngre Kataa. 1 July, 2008.

- Description:
- The circular outline of a burned basin (Feature 3) is bracketed by photo scales (left of center) in unit 50N 4W (130 cm below the unit datum) at Mound 6. A pottery jar sits to the right side of the basin, its opening covered by a potsherd lid. To the left, a grinding stone sits, grinding surface down, over top of another pottery jar. Another grinding stone (far left) sits at a higher level in unit 50N 6W. A second burned feature is associated with a grinding stone tipped on its side, far right. Another pottery jar sits nearby, also lidded with a broken sherd. Burned features like these were associated with metal working in this Mound 6 workshop area. Photo scale at bottom in centimeters.

- Description:
- Partial iron projectile point, the tip of the head (left) broken off. The base of the head forms a right angle barb with the short tang. The tang (right) would have been inserted into a shaft made of bamboo, reed or lightweight wood to form an arrow. This point was found in an area (mound 7) that archaeologists interpret as a house mound. The artifact is corroded by rust. Scale in cm. Length: 9.1 cm. Weight: 13.6 g. Site Ngre Kataa. 4 June 2009.

- Description:
- A large insitu anvil/grinding stone in an area interpreted by archaeologists as a metallurgical workshop. It is associated with several smaller stones that show signs of use as grinding or hammer stones. On the northwest side of the stone is a partial pottery vessel--unusual for its layered construction (NK 09-787). To the right of the partial pot are two flat iron discs (larger, above, SF 09-370 and smaller, below SF 90-371). The smaller grinding stone (upper left of photo) rested, grinding surface down, on top of a pottery jar (NK 09-788) which was exposed in the next excavation level. Photo scale bar in 5 cm increments. Photo arrow pointing north. Site Ngre Kataa. 4 July 2009.

- Description:
- 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.

- Description:
- A piece of a copper alloy (brass) bar, found in association with burned features that archaeologists interpret as linked to metalworking (left: side view; right, end views). The bar is square in cross-section (right). One end appears finished and has a slight circular depression or dimple (bottom right). The other end (top right) is jagged and appears to be broken from a longer bar. The artifact was recovered from soil associated with an amorphous burned feature, underneath which were a series of burned basins likely created by forging activities. The object is similar in appearance to brass bars known from the Ma'adin Ijafen cache of brass ingots documented by Theodore Monod in eastern Mauritania in the 1960s. As such, this may be the form in which metalworkers got the copper alloys that were worked at the site. Length: 1.7 cm. Weight: 2.8 g. Scale in cm. Site Ngre Kataa. 25 June 2009.

- Description:
- A large insitu anvil/grinding stone in an area interpreted by archaeologists as a metallurgical workshop (two views). It is associated with several smaller stones that show signs of use as grinding or hammer stones. On the northwest side of the large stone (GS 09-15) is a partial pottery vessel--unusual for its layered construction (NK 09-787). Sitting adjacent to the partial pot are two flat iron discs (larger one, above in photo 1, SF 09-370 and smaller, below in photo 1, SF 90-371). A smaller grinding stone (GS 09-24) sits northeast of the anvil stone, positioned with its grinding surface down. It rested on top of a pottery jar (NK 09-788) which was exposed in the next excavation level. An area of fire-hardened sediment to the southeast of the anvil stone (photo 2) is interpreted as part of a forging feature. Photo scale bar in 5 cm increments. Photo arrow pointing north.

- Description:
- A flat, thin iron disk. The object is corroded by rust. Its function is unknown. The disc was found in close association with a large anvil or grinding stone and adjacent to a distinctive pottery vessel and a smaller, irregularly shaped piece of flat iron (SF 09-171). This group of objects was located within an area (mound 6) that archaeologists interpret as a metallurgical workshop. Scale in cm. Width: 9.4 cm. Thickness: .2 cm. Weight: 49.3 g.
