Gold fill (also called gold overlay or gold-filled) is 50 to 100,000x longer lasting than gold plate. It's made by using heat and pressure to apply a layer of karat gold to a base of less costly metal (usually brass). This produces a surface with karat gold. The minimum layer of karat gold must equal at least 1/20 of the total weight of the item. See illustration for more info.
