Lost-wax casting technique

Definition

Lost-wax casting is a metalworking process used to create intricate metal sculptures and objects by forming a wax model, which is then encased in a mold. When heated, the wax melts away, leaving a hollow space that can be filled with molten metal, allowing for precise and detailed designs. This technique was vital for creating official portrait types of Augustus, enabling artists to replicate his likeness with remarkable fidelity.
