The lost-wax process is a method used to create metal sculptures and objects. It begins with making a model from wax, which is then covered in a heat-resistant material to form a mold. Once the mold is set, the wax is melted and drained away, leaving a hollow cavity in the shape of the original model. Next, molten metal is poured into the mold to fill the space left by the wax. After the metal cools and solidifies, the mold is broken away, revealing the finished piece. This technique is often used in creating bronze sculptures and jewelry, allowing for intricate details and designs.
