Excavations in units 42N 4W and 44N 4W have exposed clusters of pottery, grinding stones, tuyeres and an area of burned soil associated with metal working at mound 6, Ngre Kataa. Foreground, bottom right, are a partial pottery jar (NK 08-520) and a small flat grinding stone (GS 08-12; partially visible). To the left (west), framed by photo scales, is a burned feature. Next to it sits a hand-held hammerstone (GS 08-11). Above (to the north), a cluster of pottery and a partial tuyere (NK 08-284) are visible along the boundary between excavation units (marked by stakes). To the right of that cluster (east), a grinding stone (GS 08-10) has been pedestaled where it was found, resting with its working surface face down. Two pottery vessels sit at a slightly lower level (NK 08-406). Top center of the photo, at the far end of the excavated area, a cluster of anvil stones is visible (GS 08-05 to 08) in excavation unit 46N 4W. Photo scale adjacent to burned feature marked in 5 cm intervals. View looking north. Site Ngre Kataa. 7 July 2008.
Wide view of excavation unit 44N 6W in an area (mound 6) that archaeologists interpret as a metallurgical workshop. Lower left, below the unit's corner stake (44N 6W), the partial rim of an everted jar (NK 08-408) has been pedestaled. It rests with its rim down. Between it and a large anvil stone (GS 08-25, center photo) is a smaller light-colored stone (GS 08-21) and piece of a jar rim. Another jar rim (NK 08-409) has been pedestaled in place to the left (east) of the anvil stone. Behind the anvil stone, an everted-rim jar (NK 08-407, photo stick in front) has been partially exposed. In the unit's center, to the right of the anvil stone, the rounded edge of a burned feature is visible. To the right (west) and in front (north) of that, a photo scale sits alongside an iron projectile point (SF 08-112). The soil around it has been dampened to aid excavation (dark circular area). To its right (west) is another piece of a worn grinding stone (GS 08-20). Visible in the adjacent units (left, east) is a grindstone (GS 08-10) which has been pedestaled in place and to its right a cluster of pottery and a tuyere (NK 08-284). View looking south. Photo bar marked in 5 cm intervals. Site Ngre Kataa. 7 July 2008.
An iron bangle (SF 08-182) made by coiling a flat iron rod with thinned pointed ends. The bangle was found in association with pottery, other bangles and artifacts (cluster A). Archaeologists interpret this context as part of a larger shrine feature (clusters A-D) that capped a metallurgical workshop. The bangle shows signs of corrosion by rusting. Scale in cm. Width: 8.2 cm. Weight: 38.8 cm. Site Ngre Kataa. 15 July 2008.
An iron bangle (SF 08-183) made from a spiral-twisted round iron rod with overlapping ends. The bangle was found in association with pottery, other bangles and a dog cranium and jaws (cluster B). Archaeologists interpret this context as part of a larger shrine feature (clusters A-D) that capped a metallurgical workshop. The bangle shows signs of corrosion by rusting. Scale in cm. Width: 9.5 cm. Weight: 115.5 g. Site Ngre Kataa. 15 July 2008.
A pottery lid (NK 09-626) is positioned vertically with its interior surface facing south. Above it (slightly right) is a poorly preserved, friable dog skull. A large tree root has been truncated above and left of the pot lid. Beneath the lid is an iron bangle (SF 09-219), angled upward. The bangle is pressed up against a dog mandible, which has been placed at a diagonal angle below the pot lid, its mandibular joint oriented upward. Several teeth remain in the mandible. A burned feature can be seen immediately below this assemblage of objects. This cluster (B, 11) was part of a larger set of clusters (A-D) that archaeologists interpret as a shrine in a metallurgical workshop. Photo scale at top in cm. Arrow pointing north. Site Ngre Kataa. 16 June 2009.
A fragmented pottery lid (NK 09-626) is positioned vertically with its interior surface facing south. A large tree root is visible behind the lid, below the sign board. A dog cranium positioned above and an iron bangle placed below the lid have been removed. Additional excavation has exposed several pottery rim sherds below a dog mandible, which is positioned diagonally below the pot lid with its mandibular joint oriented upward. Several teeth remain in the mandible. A second less well-preserved dog mandible has been exposed below this. A burned feature can be seen immediately below this assemblage of objects. This cluster (B, 11) was part of a larger set of clusters (A-D) that archaeologists interpret as a shrine in a metallurgical workshop. Photo scale marked in 5 cm increments. Arrow pointing north. Site Ngre Kataa. 30 June 2009.
An iron bangle (SF 09-219) made from a round iron rod, its ends fused to create a continuous circle. The bangle was found beneath a pottery lid in a composition that included a dog cranium and jaw bones (cluster B/11). Archaeologists interpret this context as part of a larger shrine feature (clusters A-D) in a metallurgical workshop. The bangle shows signs of corrosion by rusting. Scale in cm. Width: 7.6 cm. Weight: 26.8 g. Site Ngre Kataa. 16 June 2009.

An insitu anvil stone (GS 08-25) is surrounded by several fragmentary and one complete pottery vessel (NK08-407) in an area that archaeologists interpret as a metallurgical workshop. At the top and center (southeast) is a cluster of sherds from a broken pot and a piece of a tuyere. In the lower right, to the west of the anvil stone and framed by photo scales, is a circular burned feature (Feature 2) with an outer ring of oxidized red sediment (Munsell 2.5YR 5/6) and a yellowish red (Munsell 5YR 4/6) center. Features similar to this appeared across this workshop area and may have been created by exposing rounded base containers to high heat. A yellow glass bead (SF 08-234) was found in the fill of a shallow feature characterized by ashy soil and charcoal located immediately south (lower right) of the burned feature. Black-and-white photo scale marked in 5 cm increments. View looking southeast. Site Ngre Kataa. 8 July 2008.
A barrel-shaped drawn glass bead (SF 08-234), opaque yellow in color. The bead is somewhat asymmetrical in shape and has angled ends. Compositional analysis of the bead (via LA-ICP-MS) showed it be made of mineral soda alumina (m-Na-Al) glass, probably produced in South Asia. The bead was found in the fill of a feature adjacent to a circular area of burned soil in a context (mound 6) that archaeologists interpret as a metallurgical workshop. Scale in cm. Length: 4.6 mm. Weight: 0.18 g. Site Ngre Kataa. 17 July 2008.
