mosaic gold[mō′zā·ik ‚gōld]
extremely thin metallic sheets having a golden color and used mainly for decorating both metallic and nonmetal-lic articles. Mosaic gold can be prepared from gold, from silver coated with gold, or from an alloy of copper with zinc and other metals. The sheets can also be prepared from a combination of silver and aluminum, in which case the sheet is applied to the article to be decorated and then covered with a transparent yellow lacquer.
Stannic sulfide (SnS2), used as a pigment in paints that imitate gilt, is also referred to as mosaic gold.
