Who Invented Electroplating Jewelry ??
It was the German Moritz Hermann von Jacobi who, in 1837, officially invented the electroplating procedure.
- when was electroplating invented?
- The method was disconcertingly simple.
It consisted of immersing in a bath, in which the electrolyte was the metal salt, the object to be coated, converted into a conductor of electricity, that is, acting as a cathode.
His first operation was silver, and for this feat, carried out in Russia, Jacobi won the esteemed Demidof award.
The procedure was quickly internationalized since it allowed obtaining copper or bronze medals and coins covered with silver. For example, making copies, creating the silver metal industry and, in the long run, allowed nickel plating and chrome plating of metal parts.
Origin of electroplating
For practical purposes, the origin of electroplating is found in the year 1800, when the first electric battery was manufactured by the Italian Alessandro Volta.
what is the origin of electrodeposition?
It was then observed that the zinc sheets, interspersed with the copper sheets, deteriorated rapidly.
From 1801, it was found that if a zinc, copper, or silver module was deposited on the cathode, it was soldered to it, and Jacobi’s specific invention consisted in fact in making the bath an electrolyte of the metal to be deposited.
- We can anticipate that the premises of electroplating were established by numerous physicists, who after the discovery of the voltaic pile, made various experiments with the help of the latter.
- But we can also admit that the origin of electroplating is older, dating back to the 16th century.
- At the time when the alchemists found that an iron rod immersed in “blue vitriol”, that is, in a solution of copper sulfate, was decomposing.
The iron became a kind of ferruginous paste (which was the beginning and the end of illusions about transmutation). This experiment indeed showed that it was possible to dissolve metal in a liquid.
Predecessors of electroplating
It is even possible to go back the electroplating procedure much further back, for example, to the electric battery of Parthian origin, discovered in 1957 among the artifacts preserved in the Baghdad museum.
It is supposed to date from 250-224 BC. of C. and could serve to provide electricity in silver operations if at least we allow ourselves to be carried away by speculation.
If we want to deepen the hypothesis practice of electroplating in antiquity, we see that there is no satisfactory explanation for certain plated steel gold and silver on objects of ancient goldsmiths. These plates are sometimes so thin that hammering cannot be used systematically.
