Large, shallow blackened clay bowls with interior striations are used in cooking and for eating. Cooks use them together with a small double-sided wooden pestle to grind pepper and cooked vegetables like "garden eggs" (small eggplants) for soups. They are also used as men's eating bowls (pԑԑ in Nafaanra). Bowls with striated interiors are occasionally found on archaeological sites in the Banda area, but this particular blackened form was not common until the 20th century when it was introduced from areas to the south. Potters in the region began to produce the bowls for sale both locally and at regional markets. During the 1980s and 1990s, this became one of the most popular pots made for market sale.
