Odundo's ceramics are made using hand-building and coiling techniques. She purposefully chose not to use the wheel, preferring instead to shape her vessels without its restraints of rotational symmetry. Several pieces are produced simultaneously, often taking days or even weeks to complete. When leather-hard, each is burnished, covered with slip, and burnished again. The work is then fired in a gas kiln-in an oxidizing atmosphere for the bright red-orange terracotta color, or they are multi-fired in an enclosed chamber with wood chips and shavings to create a carbonizing atmosphere for the black and semi-black pieces. Because of the alchemy of the oxygen reduction in the container, the carbonization is not entirely predictable, certain areas of the surface have wonderfully unexpected variations in coloration or even dramatic flashes of red.
