11. Excavations at a metal working area, Ngre Kataa, 2009

Description:
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.

18. Copper alloy (brass) bar, Ngre Kataa, 2009

Description:
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.

19. Brass casting mold and bottle opener, Kumasi, 2009

Description:
Skilled craftsmen at the Centre for National Culture in Kumasi, Ghana demonstrate techniques of lost wax casting by making souvenir items like the brass bottle opener pictured here (bottom left). To the right (and top left) is a discarded lost-wax-casting mold that has been broken open to remove the finished objects. This mold produced two bottle openers. The inside of the mold shows the impressions left by the original wax models when they were encased in ashy clay (black matrix). Visbile toward the base of the casting mold are impressions of the tubes, out of which the melted wax drained and through which the molten brass was poured to fill the mold. Brass bottle opener height: 9 cm. Kumasi, Ghana. 4 July 2009.

20. Insitu grinding stone, Ngre Kataa, 2008

Description:
A large grinding stone (GS 08-04) rests insitu along the south edge of unit 48N 4W in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The stone's visible surface is concave in profile, a result of use. The surface that is oriented face down exhibited greater wear from grinding. The white marks on the stone's upper surface were created by excavators' tools as they dug. A piece of copper alloy rod (greenish in color, SF 08-53) is visible insitu in soil below the center of the grindstone. Root fragments are seen in the surrounding soil. Photo scale in cm. View looking south. Site Ngre Kataa. 1 July 2008.
