Two views of a twinned lost wax cast copper alloy figurine from Ngre Kataa, Mound 6, Unit 44N 6W, Feature 5 cluster. Height: 5.9 cm. Weight: 31.3 g. Ngre Kataa, 19 July, 2008.
Banda Research Project team members Kofi Paul and Kofi Nsia screen soil from a Mound 7 excavation unit at Ngre Kataa as team member Idrusu brings another headpan of soil. The excavated soil is sieved through 1/4 inch mesh screen in order to recover artifacts (fragments of pottery, metals, beads, animal bone) that will be bagged, cataloged and studied. Studying these objects and the contexts from which they were recovered (their provenience) helps archaeologists to learn about the daily lives of past people. Ngre Kataa, 9 July, 2008.
Archaeological team member Enoch Mesah (left, white shirt) explains what archaeologists have been learning through excavation of Mound 7 at Ngre Kataa. He addresses Tolɛɛ Gbankama, chief of Nyire (standing, center, white shirt) and accompanying Nyire elders during a site visit. Archaeological team member Kofi Nsia pauses excavation during the conversation, the short-handled hoe with which he is working resting on the ground in front of him. Ngre Kataa, 6 July, 2009.
Archaeological excavations of Mound 6 at Ngre Kataa in 2009 expose a workshop where blacksmiths produced iron and copper-alloy tools and ornaments. The mound is being excavated in 2 x 2 meter units named for the coordinates of their northeast corner. In unit 50N 0W (foreground), an area of burned soil marks the location where blacksmiths heated metals. A pottery jar sits in place to the right. In surrounding units (50N 2W, 48N 0W, 48N 2W) are large anvil stones where the hot metals would have been hammered and shaped through forging. The mound's stratified deposits suggest that the workshop area was used for many decades, and perhaps centuries, between the years of about 1350 and 1520 CE (Common Era). View across the mound from the northeast looking towards the southwest. Site Ngre Kataa. 27 June, 2009.

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.
Banda Research Project team members Amanda Logan (right) and Amy Groleau (left) draw a plan map of units 44N 4W and 44N 6W, Mound 6, Ngre Kataa. They map in situ artifacts and features, including several large grinding stones, a whole pot, pottery clusters and a tuyere fragment. Wooden stakes mark the corners of 2 x 2 meter excavation units. A photo scale place near a partially exposed everted rim jar in unit 44N 6W (NK-08-407) is in 5 centimeter increments. Ngre Kataa, 7 July, 2008.
Excavations in unit 42N 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, left, a grinding stone (GS 08-10) rests with its working surface face down. It sits at a slightly higher level than a nearby (left) whole pottery jar (NK 08-406). To the right of these, a partial pot (NK 08-282) and a tuyere fragment (NK 08-284) are clustered together with two halves of a broken pottery jar, lying with its exterior surface facing down. To the south (behind), near the sign board and framed by photo scales, is a burned feature. Next to it sits a hand-held hammerstone (GS 08-11). Another partial pottery jar (NK 08-520) and a small flat grinding stone (GS 08-12) have been exposed to the left of the sign board at 77 cm below the unit's datum. The narrow dark bands visible in the soil are the traces of animal burrows. Photo scale adjacent to the sign board in centimeters. View looking south. Site Ngre Kataa. 7 July 2008.
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 deeply worn grinding stone (grindstone 1, NK-08-112) removed from levels 1-2, unit 44N 4W, Mound 6, Ngre Kataa, photographed at the side of the excavation unit. The grinding stone was found in association with other grinding stones, tuyere fragments and whole and partial pots. When found, the grinding stone was oriented with its working surface facing downward. It was located adjacent to a concentration of dark soil (feature 1) that contained abundant oxidized sediment, slag and broken pottery. Archaeologists interpret the features at Mound 6 as facilities used to make and process metals. Photo scale in 5 centimeter increments. Ngre Kataa, 2 July, 2008.
The circular outline of a burned basin (Feature 3) is bracketed by photo scales (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. Burned features like these were associated with metal working in this Mound 6 workshop area. Photo scale at bottom in centimeters. Site Ngre Kataa. 29 June, 2009.

The mouth of a perforated shrine pot (left) is covered with the pedestaled base of another pot. It remains in situ as the surrounding areas of unit 46N 2W are excavated to lower levels. Behind, the stratified layers of Mound 6 are visible in the unit's north wall. Center (back) are a series of anvil and grinding stones exposed at higher mound levels in other excavation units. During excavations in 2008, a cluster of four anvil/grinding stones was found at a level slightly higher than but adjacent (left/west) to the perforated pot. At right, in lower levels, two grinding stones rest at an angle in association with a burned feature. Archaeologists interpret Mound 6 as a metallurgical workshop at which stratified levels built up through repeated use of the same location. Photo scale in centimeters. Site Ngre Kataa. 2 July, 2009.
Photo of a partial rim and neck of a mica- and red-slipped everted jar, with vessel profile depicted, left. Red slip has been applied to the rim. Overall mica slip covers the area from the neck down. The neck area is decorated with closely spaced horizontal grooves, with mica slip applied over top. A row of dentate (comb) impression marks the transition to a mica-slipped, but otherwise undecorated, body. INAA sample ("Banda 40-11") assigned to the "L" group of ceramic fabrics; therefore, likely made from clays mined west of the Banda hills. Rim diameter 24 cm at exterior lip. Neck diameter 16 cm at interior constriction. Scale in cm. Ngre Kataa (Banda 40), 30 March, 2001.

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.
Photo of an everted-rim jar excavated from Ngre Kataa, Mound 1, Unit 1, levels 3-6. The jar (Vessel 1) was found upside-down, resting on its rim and in association with a cluster of several other complete (Vessels 2 & 3) and broken pots in what has been interpreted as a kitchen area. The round-based jar is decorated on its lower surface by faint twisted cord-roulette impressions. The zone of cord rouletting is separated from the undecorated surface above by three arching grooves or channels. Multiple small circular punctates mark the place where grooved lines meet. Whole pot. Rim diameter c. 30 cm at exterior lip. Photo scale in cm. Site Ngre Kataa ("Banda 40"). 5 April, 2001.
A light-colored slurry plaster marks the outlines of earthen walls exposed through excavations at Mound 7, Ngre Kataa. The upside down "T" shape shows the intersection of two walls. The vertically oriented wall is made from a lighter colored clayey soil compared to the darker horizontally oriented wall. Both walls were coated on the inside and outside with a thin plaster, appearing as a light-colored thin line exposed as archaeologists excavated the horizontal level. A red-and-white photo scale lies across one of the walls near a north arrow and a photo board with provenience information. Ngre Kataa, 6 June, 2009.

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.

Ann Stahl takes notes on excavation Unit 1, Mound 1 at Ngre Kataa ("Banda 40") in preparation for further excavation of the unit, originally opened in March 2001 by Leith Smith as part of a regional site testing project. A partially complete everted-rim jar ("Vessel 4"), oriented with its mouth down, is visible in the profile wall (left). Two trowels rest on the ground surface just above the jar. To the right on the ground surface is a Munsell Soil Color Charts book resting on top of a clip board and graph paper used to draw a profile map. Ngre Kataa, 19 June, 2001.
Insitu pottery and iron artifacts associated with clusters B and C of what archaeologists interpret as a shrine (clusters A-D) which capped stratified deposits in a metallurgical workshop. Far left in unit 48N 10W, the flat surface of an anvil/grinding stone (GS 09-32) is exposed, to the left (west) of which a poorly preserved portion of an elephant tusk was found (now removed). To the right (east) of the large stone is Cluster B, which includes the group of sherds seen in the vertical exposure in front and left (west) of the tree stump. Behind the tree stump is a large cluster (C) of pottery lids, partial pots and iron objects. Photo scale marked in 5 cm increments. View looking towards northwest. Site Ngre Kataa. 10 June 2009.
Insitu pottery and iron artifacts associated with clusters B-D of what archaeologists interpret as a shrine (clusters A-D) which capped stratified deposits in a metallurgical workshop. Bottom left, at the base of a balk supporting the unit peg, is cluster D, comprised of two stones flanking an iron disc, laid flat (SF 09-158), and a tri-looped iron bangle (SF 09-159). In front and left (east) of the tree stump is a large cluster (C) of pottery lids, partial pots and iron objects, including an iron bangle (SF 09-148) and a pair of miniature iron manacles (SF 09-171, "B"-shaped object). To the right (west) of the tree stump, another cluster of pottery and iron objects can be seen. Top right of the photo, a yellow notebook rests on top of an anvil/grinding stone (GS 09-32), next to which rested a poorly preserved section of an elephant ivory tusk. North arrow photo scale marked in 5 cm increments, arrow pointing north. View looking towards southwest. Site Ngre Kataa. 10 June 2009.
Photo of an everted-rim pottery jar excavated from Ngre Kataa, Mound 4, Unit 1, Levels 5-6. The jar (Vessel 1) was located in the north profile wall of the unit, together with another vessel (Vessel 2).
The jar has a carinated shoulder and a rounded base. To the right and below the carination, a portion of the exterior surface has broken away. The upper area of the jar is decorated with three horizontal grooved lines, inbetween which are lines of dentate impression. Just above the carination is another line of dentate impression and a grooved line. To the left and right, on the upper side of the carination, sets of two triangular designs were applied, consisting of three punctates connected by two short grooved lines. The area inside the triangle is marked by crossed dentate impressions, forming an "X" inside the triangle. This design was repeated twice on the recovered portion of the jar. It was likely repeated a third time on the missing portion. Below the carination are two shallow horizontal grooves. The jar's base is smooth, with no surface treatment applied. Roughly 65% of the vessel was recovered. Rim diameter 25 cm at exterior lip. Photo scale in cm. Site Ngre Kataa ("Banda 40"). 5 April, 2001.
Photo of an everted-rim pottery jar excavated from Ngre Kataa, Mound 4, Unit 1, Level 5. The jar (Vessel 2) was located in the north profile wall of the unit together with another vessel (Vessel 1). The jar has a carinated shoulder and a rounded base. The upper area of the jar is decorated with three horizontal grooved lines inbetween which are lines of dentate impression. The base of the jar is surface treated with a twisted cord roulette. Two roughly parallel horizontal grooved lines separate the cord rouletted zone from a plain zone below the carination. A hole in the base of the pot (ca. 7 cm across) may have been deliberately broken in this otherwise whole pot. Rim diameter 22 cm at exterior lip. Photo scale in cm.

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.
View across open excavations in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The photo centers on units 46N 8W (foreground) and the southern half of 48N 8W, the north wall of which (at 47N) can be seen behind the sign board. The exposed areas were excavated in 2008 and the photo taken in preparation for 2009 excavations. Traces of circular burned features, red-orange and yellow in color, can be seen in the freshly scraped surface of these units. The uppermost north arrow sits to the right (east) of the circular outline of a still-buried everted-rim jar. Another everted-jar rim can be seen exposed in the north wall at 47N. This rim and associated artifacts formed cluster B, part of a larger shrine feature (clusters A-D) that extended across the northern half of unit 48N 8W (beneath and behind the small tree trunk visible above and left of the sign board). Cluster A (unit 46N 8W) comprised a large pottery bowl surrounded by six iron bangles that was removed in 2008. It was positioned above and slightly west (left) of the burned feature (center photo) that is intersected by a tree root. Cluster B included the artifacts seen here in the north wall at 47N, together with an associated cluster of a pedestal-handled pot lid, dog skull and jaw bones revealed by further excavation beneath and west (left) of the tree stump. In the upper right of the photo (north and east), insitu anvil (GS 09-15, left) and grinding (GS 09-12, right) stones are visible in unit 50N 6W. Photo scales marked in 5 cm increments and measuring tape marks 2 m. Arrows pointing north. Site Ngre Kataa. 6 June 2009.
Insitu pottery and iron artifacts associated with clusters C and D of what archaeologists interpret as a shrine that capped stratified deposits in a metallurgical workshop. Cluster D appears in the foreground, left, below unexcavated soil remaining around the 48N 8W unit peg. Here two small stones flank a flat iron disc (SF 09-159, left) and a tri-looped iron bangle (SF 09-158, right). Cluster C is a large grouping of pottery and iron objects located north of the tree stump, center photo. Included were several whole pottery lids, a broken but mostly complete jar associated with an iron bangle (SF 09-148) and a pair of miniature iron manacles (SF 09-171). The bangle is visible, resting on a soil pedestal in front of the tree trunk's center. In the photo's upper right, a large anvil stone (GS 09-32), on which sits a yellow notebook, is visible. Flanking this stone on its western edge was a portion of an ivory tusk. Photo scale marked in 5 cm increments. Arrow pointing north. Site Ngre Kataa. 10 June 2009.
Insitu pottery and iron artifacts associated with cluster C of what archaeologists interpret as a shrine (clusters A-D) that capped stratified deposits in a metallurgical workshop. Center photo are two large pieces of an everted-rim jar, its exterior surface facing outward. Immediately above is a large portion of the same pot, its interior surface facing outward. Found positioned against the jar's interior surface was a pair of miniature iron manacles (SF 09-171, "B"-shaped object). An iron bangle (SF 09-148) was positioned at the jar's mouth, above the manacles. To the left of the bangle is the upper edge of a large grinding stone (GS 09-26), which later excavations revealed to be oriented with its grinding surface down. To the right of the bangle, a pedestal-handled pot lid (NK 09-381) rests with its interior surface oriented upward. At center photo, bottom, a pot lid with a strap handle (NK 09-382) rests on its side. To the right of the north arrow, portions of an another pedestal-handled pot lid lie with its interior oriented upward. Photo scale at upper right marked in cm. Arrow pointing north.

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 cluster of burned features is exposed in the northwest corner of excavation unit 50N 8W in an area interpreted by archaeologists as a metallurgical workshop (mound 6). Along the unit's west wall (left in photo) is an amorphous zone of fire-hardened red (Munsell color 2.5YR 3/6) matrix. A piece of brass bar (SF NK 09-293) was found in soil associated with this burned feature. Above and to the right (northeast), two circular burned features are visible in outline. These basin-shaped features had a thin lining of fire-hardened sediment, red to dark red (Munsell 2.5 YR 3/6 & 4/8) in color. The basins were filled with loose ashy sediment and small pieces of charcoal. A sample of burned matrix from feature 1 (top right basin) yielded a thermoluminescence (TL) age estimate of 1500 +/- 40 CE (Univ. Wash. 2455). Further excavation revealed additional basin-shaped features beneath the amorphous burned feature. The excavation unit's northwest corner peg is visible, upper left. View looking north.

Excavations uncovered three insitu boulders placed in a row that were used as anvil stones in an area interpreted as a metallurgical workshop. Multiple surfaces of the boulders show signs of wear caused by hammering and grinding. Repeated use of the anvil stone in the foreground (GS 09-03) has created a clear depression on its upper surface and its left side is flattened by wear. The middle anvil stone (GS 09-02) has multiple depressions created by use on its upper surface. The anvil in the rear of the photo (GS 09-01) shows wear on its top and side surfaces, with dirt still embedded in a deep cup-shaped depression on its south-facing side in this photo. To the east (right) of the boulder in foreground, the flat surface of a grinding stone (GS 09-04) is visible in the east wall of the excavation unit. A broken pedestal base of a pot sits on its side to the east (right) of the middle anvil stone. In the upper left corner of the photo, a burned feature interpreted by archaeologists as the remains of a forge has been exposed. The red-and-white band above the photo sign is a two meter scale, marked in 10 cm increments. View looking north across two exavation units: 50N 2W (top of photo) and 48N 2W (bottom of photo).

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.
The southeast corner of excavation unit 50N 0W in mound 6 shows stratified layers that accumulated in an area interpreted as a metallurgical workshop (mound 6). An anvil stone (top of photo; GS 09-06) is pedestaled insitu in the adjacent excavation unit (48N 0W). This stone was found immediately below the mound's top surface. A smaller grinding/anvil stone is visible in the east wall of unit 50N 0W, at a depth of one meter below. Burned orange-red lenses that archaeologists interpret as features associated with processing metals are visible in the strata between the stones. Evidence suggests that these layers built up through repeated use of this location for metalworking activities. Stadia rod numbered intervals of 10 cm. View looking south. Site Ngre Kataa. 9 July 2009.
The south wall of excavation unit 50N 0W in mound 6 shows stratified layers that accumulated in an area interpreted as a metallurgical workshop. An anvil stone (GS 09-06; left of the sign board) is pedestaled insitu in the adjacent excavation unit (48N 0W). Other pedestaled grinding stones are visible to the right and behind the sign board. These stones were found just below the mound's top surface. A smaller grinding/anvil stone is visible in the east wall of unit 50N 0W, at a depth of one meter below the anvil stone. Burned orange-red lenses that archaeologists interpret as features associated with processing metals are visible in the strata between the stones. Ashy lenses are visible in the south and west walls. Evidence suggests that these layers built up through repeated use of this location for metalworking activities. Width of unit: 2 meters. Site Ngre Kataa. 9 July 2009.
View across four excavation units, looking west across an area interpreted as a metallurgical workshop. An anvil stone (GS 09-01) sits insitu in the foreground in unit 50N 2W. In the northwest corner of the same unit (below the roll of red flagging tape, right), the remains of a partially excavated burned feature interpreted as a forge are visible. A pottery jar (NK 09-686), lidded with a broken rounded base of another pot, is visible in the next unit (50N 4W). It sits adjacent to another burned feature in the unit's northwest corner (behind the pot, not visible in this photo). The jar is overlaid by another burned feature (visible as a layer of orange soil). A second pot (NK 09-685), to the left of the first, is covered by a flat stone (GS 09-13) whose lower surface shows evidence of grinding. A larger flat U-shaped grinding stone (GS 09-12) sits insitu atop a soil pedestal in the northeast corner of the next unit (50N 6W). To the south (left) of the stones, a partially exposed jar rim (NK 09-749) is visible close to the eastern edge of unit 50N 6W). Behind it, a large anvil/grinding stone (GS 09-15; faintly visible because it blends into the surrounding soil color) is partially exposed, with a smaller hammer/grinding stone (GS 09-16) sitting in front and left (south) of the large stone. A smaller grinding stone (GS 09-19; upper left of photo) has been pedestaled insitu in the farthest unit (50N 8W). Subsequent excavations in unit 50N 8W revealed a series of burned features in its northwest corner. A two meter yellow tape is extended along the edge of unit 50N 4W (right).

Three burned features are visible at the base of level 6 in unit 46N 2W. Two circular features (F1, right & F2, left) have been cross-sectioned, creating a straight edge. Burned feature 3 is an irregularly shaped (rectangular) area pedestaled on the east (right) side of the excavation unit. Along the unit's west wall (left) is an unexcavated rectangular area. Within this matrix was a perforated pot (NK 09-789) lidded with the pedestal base from another pot. The perforated pot contained cowries and small fragments of iron. In units to the north (behind), a row of insitu anvil stones (GS 09-03, -09-02 and 09-01, near to far) is visible in units 48N 2W and 50N 2W. To the east (right) of these, a flat grinding stone (GS 09-08) and an anvil stone (GS 09-06) can be seen insitu in units 48N 0W and 50N 0W. A pottery jar (NK 09-790) rests insitu in the center of unit 50N 0W. To the left of the archaeologist in the blue shirt (Abass Iddrisu), a flat grinding stone (GS 09-12) and a pot (NK 09-685) lidded with a grinding stone (GS 09-13) are visible on the boundary between units 50N 4-6W.

Two views of a burned basin-shaped feature (Feature 2) in mound 6, unit 46N 2W, part of an area that archaeologists interpret as a metallurgical workshop. The feature has been sectioned to reveal its profile. Viewed from the top, the circular feature consists of a ring of fire-hardened yellowish red (Munsell color 5YR 5/8) sediment. The fire-hardened matrix is thicker at its top edge than it is at the bottom of the basin, where its color is dark red (Munsell 2.5YR 3.6). In profile view (second photo), the basin appears as a narrow band of yellowish red fire-hardened sediment. The fire-hardened sediment is thin and rounded at the base of the basin, suggesting that it may have formed around a round-based vessel used to heat metals. A thermoluminescence sample of the burned matrix yielded a date of 1490 +/- 50 years (Univ. Wash. 2364). Photo scale in cm. Site Ngre Kataa. 23 June 2009.
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.
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.

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 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.
A tree that took root atop a shrine cluster has been cut back to a stump (center photo). Most of the objects in the shrine clusters (B-C) have been removed. To the left and below the tree stump, clusters of pottery (10 & 11) can be seen, including a red-colored pottery lid oriented vertically (cluster 11). An iron bangle, a dog cranium and dog mandibles were found associated with that lid. To the right (north) of the stump, a tri-looped iron bangle (SF 09-218) has been pedestaled (left of the black-and-white photo scale stick). The level above this had been covered by a cluster (cluster C) of pottery, including several pot lids, together with an iron bangle and a miniature pair of iron manacles. To the east and west, two large anvil stones are visible, one to the right (east) of the tree stump (GS 09-26) and one to the left (west, GS 09-32). To the left of the stump, a burned feature is visible below the pottery cluster (cluster 11). Photo scale bar marked in 5 cm increments. Arrow pointing north. Site Ngre Kataa. 16 June 2009.

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.
A small round stone (GS 08-11) rests insitu next to an irregularly shaped area of burned fire-hardened sediment in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The stone has wear consistent with use as a hammerstone. The burned sediment was next to a circular area of soil that showed signs of oxidation through exposure to high heat. A small piece of copper alloy metal lies at the edge of the fire-hardened sediment, to the left of the hammerstone and above the right site of the photo stick. The feature is likely associated with forging activities. Photo scale at bottom marked in 5 cm intervals. View from above, north at top of photo. Site Ngre Kataa. 5 July 2008.
