Clay pots of this shape are used for cooking soup over a hearth fire. The relatively wide opening of soup pots (chiin sinyjͻlͻ in Nafaanra) makes it easy to add ingredients and stir the soup as it cooks. These soup pots are blackened, a fashion that took hold during the 20th century. Unblackened pots of similar shape are found on archaeological sites dating to the 19th century and earlier.
