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.
A potter sits on a stool as she molds the upper body of a clay water jar (chͻkoo in Nafaanra). In her right hand she uses a maize cob (bledjukaan in Nafaanra), pulling it against the exterior surface to smooth and thin the clay. In the foreground are water jars whose leather-hard upper body and rim have been joined to a rounded base, their clay bases still moist and not yet smoothed. Large wooden mortars and a headpan containing moist clay sit nearby as she works in the shade of an open-sided room. Dorbour, 1994.
This short video made from still photographic images illustrates the firing techniques of Banda-area potters. It shows examples of bonfire firing and post-firing treatment of vessels in a solution of pounded bark. Images include a 1982 sequence following Mo potters in Bondakile and 1994 images of Nafana potters in Adadiem and Dorbour, featuring Afua Donkor and Yaa Nsiah Adiemu from the latter. Original images used to make the video are available in the Banda Through Time Repository. Bondakile, 1982. Adadiem, Dorbour, 1994. Length: 4.22 minutes.
