Skilled craftsmen at the Centre for National Culture in Kumasi, Ghana demonstrate techniques of lost wax casting by making souvenir items like the brass bottle opener pictured here (bottom left). To the right (and top left) is a discarded lost-wax-casting mold that has been broken open to remove the finished objects. This mold produced two bottle openers. The inside of the mold shows the impressions left by the original wax models when they were encased in ashy clay (black matrix). Visbile toward the base of the casting mold are impressions of the tubes, out of which the melted wax drained and through which the molten brass was poured to fill the mold. Brass bottle opener height: 9 cm. Kumasi, Ghana. 4 July 2009.
