Have you ever wondered how they make an Oscar statue? Below is a link to an interesting video from the Academy of Motion Picture Arts and Sciences showing how an Oscar Statuette is made.
The Oscar is first cast in Britannium, then electro-plated in Copper, Nickel, Silver, and finally, 24K Gold. They are then mounted on a black nickel-plated base. The personal engraved tags which identify the winners are engraved after the ceremony and attached later.
