Describe the lost-wax casting process in sculpture. This casting process used for many centuries probably originated in Egypt. Later, it found it s way around the world as its popularity spread. The metal used is bronze, an alloy of copper and tin or sometimes brass, an alloy of copper and zinc. Start with a clay core.
Wax covers core and is carved into.
Rods and a pouring cup made of wax are attached to model formed by wax-covered clay. Damp sand is pressed firmly to the surface of the wax model and then model, rods and cup are encased in thick layers of clay. When the clay is dry, the mold is heated to melt out the wax. The mold is then turned upside down to receive the molten metal, heated to the point of liquification. The cast is placed on the ground to cool.
