Rolled Gold/Rolled Gold Plate

The process in which a layer of carat gold alloy is mechanically bonded to another metal. In the United States the designation ‘rolled gold’ or ‘rolled gold plate’ means that the proportion of gold alloy to the weight of the entire article is less than one-twentieth; if it is over one-twentieth it will be designated gold filled. Elsewhere the term tends to be interchangeable with ‘gold fill’.
