Detailed Solution

The above statement is true.
A duplicate metal sculpture can be made from an original sculpture using a process called lost-wax casting. This technique can be used to create intricate masterpieces. The oldest specimens of this method are thought to be about 6,500 years old and were found on gold artefacts at Bulgaria's Varna Necropolis. The lost-wax process, also known as cire-perdue, is a method of casting metal in which molten metal is poured into a mould that has been made using a wax model. The wax model is melted and then drained away after the mould has been created. Even though it is still commonly used today to create jewellery, dental implants, and works of art, it is one of the oldest known metal-forming techniques, dating back 6,000 years. Investment casting, its industrial form, is a typical method used in engineering and manufacturing to produce precision metal parts.
