Source notes [1,2,8-10]: “”This pot of a distinctive yellow clay and the striking and unusual decoration is achieved by splashing the surface with a very thick, resinous, vegetable decoction while it is still hot from baking. The vegetable matter boils off rapidly, leaving an effect almost of wood grain. It is a technique used by a number of peoples around the mouth of the River Zaire” - T. Phillips (ed.), Africa, the art of a continent (London, Royal Academy, 1995) pp:255”
Source notes [3-5]: “The film documents the making of three pots by hand. It follows the work of the woman potter from the beginning of shaping the clay to the baking and cooling process. The pots are hand spun on a rock and coiled built and then fired in an open stack of twits and logs. The hot pots are plunged into bowls of liquid. The heat of the pot causes the liquid to boil leaving the surface with wavy pattern”
