This ‘silver sandwich’ was then worked into finished pieces. At first it was only put on one side and later was on top and bottom. Modern electroplating was invented by Italian chemist Luigi V. Brugnatelli used his colleague Alessandro Volta’s invention of five years earlier, the voltaic pile, to facilitate the first electrodeposition.

Silver plate or electroplate is formed when a thin layer of pure or sterling silver is deposited electrolytically on the surface of a base metal. By , scientists in Britain and Russia had independently devised metal deposition processes similar to Brugnatelli’s for the copper electroplating of printing press plates.
Soon after, John Wright of Birmingham, England, discovered that potassium cyanide was a suitable electrolyte for gold and silver electroplating.
