Two views of a serpent-like figure made from an iron rod. The "head" of the direct metal sculpture resembles a triangular-tipped iron projectile point, similar to those found on the same site during the same time period. The body is formed by undulating S-shaped loops which are stacked atop one another to form the "tail." Kuulo Kataa, Mound 118, Unit 62W 4N, Level 1. Scale in cm. Length: 8.4 cm. 39.6 g.

A perforated pottery jar lidded with the pedestaled base of another pot sits in situ at the base of level 6, unit 46N 2W at Mound 6. The pot contained eight cowries and is interpreted by archaeologists as a shrine pot placed in association with metalworking facilities. Photo scale in 5 cm increments.

Side view of a broken pottery sherd with a large slag inclusion. The use of crushed slag as a tempering material included in potting clay is first seen in pottery associated with Ngre phase sites in the Banda area. The use of crushed slag as a temper intensifies during Kuulo phase times, after which it becomes uncommon. Ngre Kataa, June, 2008.
Iron slag is formed as a byproduct of iron smelting. Here a large slag nodule has broken in half, revealing its interior texture. At the archaeological site of Ngre Kataa, large chunks of 'bubbly' slag like this were occasionally found in household and other contexts, away from areas otherwise associated with metal-working activities. Potters at the time of the site's occupation had begun to use crushed iron slag as a tempering agent in their potting clays, which may explain why large nodules were being carried and cached in areas away from metal-working locations. Ngre Kataa, June, 2008.
An iron artifact (SF 09-031) recovered from screened soil taken from the southern end of excavation unit 50N 2W where two large boulders used as anvil/grinding stones were located. In the unit's northwest corner was a burned feature interpreted as the remains of a forge in an area where metalworking took place. The flat iron object is pointed on one end and has two rounded lobes at the other, perhaps to facilitate turning (like a key?). Its function is unknown. The object has been corroded by rusting. Scale in cm. Length: 5.7 cm. Weight: 9.3 g. Site Ngre Kataa. 30 May 2009.
Excavation of a shrine cluster, two images. The image on left shows a pottery cluster, first exposed in June 2008, as it appeared on 10 June 2009. At bottom center of this image is a pedestal base, above which is a tight cluster of rim sherds. The curved sherd on the far right in this image is the outer edge of the pedestal-handled lid, which is fully exposed in the photo on the right, taken on 16 June 2009. A dog skull in a highly friable state is visible above and to the right of this lid in both photos. In the imgae on the right, an iron bangle (SF 09-219) can be seen resting in an angled position, below and left of which is a dog mandible. These were uncovered by excavation below and behind the pedestal base seen in the picture on the left. Photo scale marked in 5 cm increments. Site Ngre Kataa. 10 and 16 June 2009.
An iron bangle (SF 09-132) made from a flattened iron rod with overlapping ends. One end of the bangle is bent inward.

Width: 7.9 cm. Weight: 25.6 g. Site Ngre Kataa. 6 June 2009.
Broken bowl of a locally made clay smoking pipe, 2 views (left: bowl interior; right: bowl exterior). Pipes like this were made across West Africa after Europeans learned the practice of smoking tobacco from First Peoples of the Americas and introduced it to Africa in early centuries of the trans-Atlantic trade. This pipe bowl has a flared pedestal base decorated with red paint. The oval bowl is decorated with vertical rows of triangular impressions, above which are two grooved lines and an area with red paint. The bowl's interior is blackened from use toward its base.

Tanged iron blade with pointed tip (left) and rounded shoulders. Two large concretions adhere to the blade's corroded surface. The tang (right) would have allowed the blade to be hafted to a wooden or bamboo shaft or handle. If hafted to a long shaft, it may have been used as a spear (chombo in Nafaanra).

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.
A flat, thin iron disk. The object is corroded by rust. Its function is unknown.

A flat, irregularly shaped iron with circular depression. The object is corroded by rust and its original form and function are unknown. It was found in close association with a large anvil or grinding stone (GS 09-15), a circular iron disk (SF 09-370) and a distinctive pottery vessel (NK 09-787).

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.

Flat, thin iron disk (SF 09-159). The object is corroded by rust and its edges notched in two spots. Its function is unknown. The disc was found in a cluster (cluster D) with an iron bangle (SF 09-158) and two stones whose surfaces showed evidence of grinding. The cluster was part of a wider feature (clusters A-D) that archaeologists interpret as a shrine, which overlaid stratified deposits in a metallurgical workshop (mound 6). Scale in cm. Width: 8.1 cm. Thickness: .2 cm. Weight: 29.8 g. Site Ngre Kataa. 9 June 2009.
A tri-looped iron bangle (SF 09-158). The bangle was formed from a single round iron rod, looped three times at the top (detail, left). The rod is joined with a single twist at the base, with each end of the rod overlaid by a thin iron strap (bottom), causing slight thickening on either side of the twisted base. The bangle was found in close association with a flat iron disc (SF 09-159) and two stones whose surfaces showed evidence of grinding (cluster D). 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: 8.5 cm. Weight: 30.2 g. Ngre Kataa. 9 June 2009.

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 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.
