What does Gold-Filled mean? How about Rolled-Gold Plate?
Gold-filled means gold bars are soldered to a base metal, then rolled into sheets to give a somewhat higher thickness of gold than any plating method. The resulting layer of gold is slightly thicker than a sheet of paper. Gold-filled cases were originally warranted to last a certain number of years in normal wear – e.g. 25 years, and are somewhat more durable than modern gold plating. This practice was common until the 1960’s, but has been largely replaced by plating processes. Rolled-gold plate was another vintage method of plating gold, except the gold was rolled out flat before being bonded to the base metal. This process has been supplanted largely by electrochemical plating and PVD.
