How long ago did people start using electroplating to coat things in metal?

It was first invented in 1805

Explanation:

First attempt was done by making a thin layer of gold onto silver by Italian chemist Luigi Brugnatelli. The metals that can be electroplated are gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum and lead. Electrolysis is identical to the electrolysis, it is the reverse of the generation of the electric current. It is the process which uses the electric current so as to decrease the dissolved metal cations which can help in forming a thin layer of the coherent metal coating over the electrode. This is also called as the electrodeposition.
