Photo of a pottery jar with a slightly everted rim (NK 08-406), found insitu in an area that archaeologists interpret as a metallurgical workshop. Above its rounded shoulder, the jar's surface is undecorated, with the possible exception of traces of red pigment in some areas. The jar's shoulder is decorated with a band of circular punctates interspersed with cross-hatched designs, repeated twice around the jar's circumference. Its base and lower body are surface treated with cord roulette in a zone bounded by a band of diagonal impressions which create a zigzag design ("/\/\"). The jar is fire-clouded in zones across its surface. The jar was found in the vicinty of a grinding stone (GS 08-10), a partial tuyere (NK 08-284) and a burned feature. Rim diameter at exterior lip: 20 cm. Vessel height: 19 cm. Site Ngre Kataa. 15 July 2008.
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.
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.
The body and base of a large pottery bowl has been exposed by exavation in unit 46N 8W. Surrounding this bowl was a cluster of sherds from other pottery vessels, now removed to expose several iron bangles of different shapes and sizes, seen insitu here. Between the bowl and the photo scale is an iron bangle (SF NK 08-169) formed from a spiral-twisted rod. Pedestaled to the right of the bowl (east) is an iron bangle (SF NK 08-140) made from a round rod that was coiled. Visible in the wall behind and to the right of the bowl (north) is a smalled coiled iron bangle made from a flattened piece of iron (SF NK 08-182). This cluster (A) was part of a larger cluster (A-D) of artifacts that archaeologists interpret as a shrine placed in a metallurgical workshop. Rootlets are visible in the wall and floor of the unit. View looking north. Photo scale in 5 cm increments. Site Ngre Kataa. 9 July 2008.
An iron bangle (SF 08-184) made by coiling a flattened iron rod, its ends rounded and overlapping. 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: 6.9 cm. Weight: 39.2 g. Site Ngre Kataa. 15 July 2008.

A cluster of four large insitu anvil/grinding stones in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The stone at the bottom of the photo (GS 08-06) was oriented with its grinding surface down (not, therefore, visible in the photo). The middle right stone (GS 08-07) also rested with its most-used grinding surface down. The largest stone (middle, left, GS 08-05) had no clear working surface. The stone at the back (GS 08-08) was associated with a fist-sized round quartz hammerstone, seen insitu slightly above. Later exavations (2009) revealed a perforated pot (NK 09-750), lidded with the base of another pot (NK 09-750), adjacent to but approximately 40 cm below this cluster in the next excavation unit. Photo scale in 5 cm increments. Arrow pointing north, view looking east. Site Ngre Kataa. 3 July 2008.
