A group of unfired clay pots to which red slip (chuma in Nafaanra) has been applied prior to firing. The string of Babobab tree seeds (foreground) is used to burnish the slip. By rubbing the dried slip vigorously with the seeds, the slip adheres to the surface and becomes shiny. To the right rear are several unfired clay eating bowls (kpokpoo in Nafaanra). Dorbour, 1994.
