The process involves applying a thin layer of gold to a base metal consisting of primarily silver. The silver alloy, often referred to as “sterling,” typically contains 92.5% silver and 7.5% other metals, usually copper. An electrical current is used to deposit gold ions onto the surface of the silver, creating a durable and aesthetically pleasing finish. For instance, a piece of jewelry may undergo this process to enhance its visual appeal.
This technique offers numerous advantages, including providing the appearance of solid gold at a lower cost. It enhances the tarnish resistance of the silver base, extending the lifespan of the item. Historically, this method has been employed to create affordable versions of luxury items and to protect valuable metals from wear. The practice dates back centuries, demonstrating its enduring relevance in metalworking and jewelry making.
