Faux gold is a term used to describe a variety of materials that are made to look like gold. Oroide and ormolu are two of the most common types of faux gold. Oroide is an alloy of copper, zinc, and tin that is electroplated with a thin layer of gold. Ormolu is a brass alloy that is also electroplated with a thin layer of gold. Both oroide and ormolu are used to create decorative objects that have the appearance of gold without the cost.
