(十字架状)耶稣受难像 - 贝宁 (没有保留价)

For ages, African bronze artifact have been made using the “lost wax method.” First a model of the object is made from beeswax, then dipped repeatedly in a solution of fine ash or charcoal powder mixed with water. This forms a mold, or “crucible,” which is allowed to dry and harden. As the molds harden,  channels are left in them  to enable the wax to drain out during the heating process which takes place in a kiln. As the wax melts and is “lost”, molten brass or gold is poured into the mold to form the ornament. When the metal has cooled, the molds are broken open and cleared away and the new art object is thoroughly cleaned and shined before it is presented to the world. In some cases the final product is gilded for an especially rich finish.
