Two views of a twinned lost-wax cast copper alloy figurine from Kuulo Kataa, Mound 118, Unit 62W 4N, Level 3. Lower "foot" plate broken off from figurine body. Height: 3.7 cm. Weight: 13.2 g. Kuulo Kataa, 15 June, 1995.
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. Kuulo Kataa, 15 June, 1995.

A copper alloy finger ring made from a rod forged into undulating S-shaped loops and joined at its ends by a flat metal plate. Two views. From Kuulo Kataa, Mound 101, Unit 2W 2S, Level 7. Height: 1.4 cm. Width: 2.6 cm. Weight: 8.4 g. Kuulo Kataa, 9 June, 1995.
Miniature lost wax cast spoon, perhaps a gold weight. From Ngre Kataa, Mound 7, Unit 14N 22E, Level 8. Length: 4.3 cm. Weight: 2.1 g. Ngre Kataa, 27 June, 2009.
A crucible used to process copper alloys from Kuulo Kataa, Mound 130, Unit 95E 102N, Level 12. Crucibles like this would have been used to heat copper alloys to a liquid state for use in casting, including casting through a lost-wax process. Scale in cm. Kuulo Kataa, 27 June, 2000.

Finger ring made from twisted copper alloy wire. From Ngre Kataa, Mound 6, Unit 44N 4W, Level 5. Width: 2.3 cm. Weight: 1.6 g. Ngre Kataa, 8 July, 2009.
A twinned lost wax cast copper alloy figurine from Ngre Kataa, Mound 6, Unit 44N 6W, Feature 5 cluster. Archaeologists interpret the Feature 5 cluster as a shrine placed among metalworking facilities. Height: 5.9 cm. Weight: 31.3 g. Ngre Kataa, 19 July, 2008.
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. Site Ngre Kataa. 24 June, 2009.
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.

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. The bangle occurred as an isolated find in the upper levels of an area (mound 6) that archaeologists interpret as a metallurgical workshop. The bangle has been corroded by rusting. Scale in cm. Width: 7.9 cm. Weight: 25.6 g. Site Ngre Kataa. 6 June 2009.
A short-stemmed, locally made clay smoking pipe, 4 views (1: front; 2: side view, pipe bowl on left; 3: stem end; 4: top, looking into pipe bowl). Pipes like this were inspired by those used by America's First Peoples from whom Europeans learned about tobacco. Europeans introduced tobacco smoking to West Africa during the early centuries of trans-Atlantic trade. This pipe's straight-sided cylindrical bowl has a flat, circular base with traces of red pigment. The bowl's rim has broken away. The stem joins the bowl above the base (referred to as a "double-angled" form). The stem flares slightly outward toward its rim. The stem's lip shows traces of red paint. The pipe's surface is unevenly blackened. The bowl is decorated with incised lines. Two horizontal lines bound a zone of repeated "X" incisions marked by traces of red pigment. Photo scale in cm. Site A212. 18 February, 2001.
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. The bowl's rim and its stem are missing. The potting clay used to make the pipe is tempered with fine white grit. Photo scale in cm. Site Kuulo Kataa. 28 June, 2000.
