Clay pots of varied sizes used to store water (chͻkoo in Nafaanra). The exterior surface of these everted-rim jars is textured with maize cob roulette and their surface is decorated with shallow grooved lines. The porous walls of these pots helps keep the liquid storied inside cool. For this reason, these pots are not treated with the bark solution used to finish cooking pots. Also, the narrow opening (neck) of the jar reduces evaporation and conserves water. Ahenkro, 1986.
