Expanding Uses
In 1840, George Richards Elkington further developed gold plating for industrial uses. He was awarded a patent and began using the gold plating to make small gold-plated items like snuff boxes and picture frames. The first gold plating manufacturing plant was opened in St. Petersburg in 1844.

Modern Uses
As the electronics industry developed in the mid-20th century, gold plating found additional uses, though in different combinations. Electronic manufacturers focused more on conductivity and corrosion resistance than its decorative qualities. Elkington's original patent has now been modified to more than 300 different U.S. patents and 100 European patents.

Many people consider gold plating's origins to have begun with mankind's discovery of gold. Even in the Stone Age, craftsmen pounded gold into thin sheets that were used for decorative purposes. Though thin sheets of gold would later be used in gold plating, these first sheets of gold were not applied to other materials.

Gold plating as it is known today was first developed in 1800. Alessandro Volta discovered electrodeposition, the science known as electroplating. It allowed for two metals to be fused together. Three years later, Luigi Brugnatelli used electroplating to apply gold plating to silver medals.

Gold does not oxidize when exposed to air, so its electrical conductivity won't diminish over time. This makes it ideal for electroplating. Gold plating acts as an anticorrosive coating to the material to which it is applied. When bonded with cobalt, the result is a wear-resistant material. These advantages make gold plating ideal for electrical switch contacts and connector pins where electrical contact occurs.

Eleventh Five-Year period, the non-ferrous metal processing industry utilization and sustainable development.

Gold is a popular material for jewelry and other items. The problem is that solid gold is expensive. To get the look of gold without the cost, a technique called gold plating was developed. It is a technique that has been around for centuries and continues because it is effective. The underlying metal is made negatively charged through chemical baths and/or electricity. Once the metal has a charge, it will seek to balance its charge. This is done by applying gold. The two metals share electrons, which creates the bond.
