What's the history of industrial electroplating 

I am writing a paper for a graduate school class describing an electroplating system, and the interfaces within this system. Is there a reference source available that could discuss when electroplating got started? (I already have background material on Volta, Galvani and Faraday in relationship to electrochemistry/electrodeposition -- just need history on the practical applications).

Thanks in advance!

First of two simultaneous responses --   The closest thing I can think of to one-stop shopping for you is a VHS video called "History of Electroplating with Al Weisberg" available from www.aesf.org. But there are dozens of journal articles from numerous countries and in several different languages including "History of Electroplating & Electroforming in Russia", "Nickel Plating - Brief History", "Early History of Gold Electroplating", "The Origins & History of Gold Plating", "History & Introduction to Brush Plating", "History of Chromium Plating", "A History of Zinc Plating", etc. You probably need to do a published lit search (not a website search) incorporating the terms 'history' and 'plating'.   Ted Mooney, P.E. finishing.com Inc. - Brick, NJ Second of two simultaneous responses --   For reasons too complex to explain here I can not get to my reference collection. I do remember that in 1984 the AESF ran a history of the association and of plating in their 75th anniversary edition of Plating & Surface Finishing. A student of industry history, if you can locate him, would be Al Weisberg, retired from Technic, Inc. but probably still reachable through them. He set up a little museum of plating history, collects antique plating photos and apparatus and has, in the past made presentations to groups regarding the history of plating. The web address for AESF (American Electroplaters and Surface Finishers Society) is AESF.org Hope this helps. Gene Packman - Syosset, NY

In the name of god I'm a student of chemistry. I didn't study about history of electroplating, but last year I read a Persian magazine that wrote that Persian in about 2000 years ago done electroplating on some coins. I am sorry that I forget magazine's name.

Thank you, Mr. Ojaghi. I think that is very possibly true, but I haven't myself seen reason to believe it is definitely true.

I think it's possible that the early Chinese did some electroplating--but I don't see any reason at all to say that they "must have known about electroplating". Further, just because something is shiny doesn't mean it's actually chromium plated--maybe silver, nickel, or zinc. There is another technology not involving electricity that was used in early cultures, i.e., surface enrichment. There a typical gold and copper alloy was cast, then acid was used to dissolve the copper and thereby gold-enrich the surface. I heard that the Aztecs did that.

I would like to hear from anyone who knows whether the chromium plating of metallic objects was performed prior to the American / German introduction of the techniques during the 20th century.

I visited the famous 'Terracotta Warriors' museum near Xi'an in China at the end of 2004.
There is a display of weaponry in the Museum from about 2200 years ago
Amazingly, it is Chrome-Plated! I am currently trying to find out how they managed this feat!

I heard of The Baghdad Battery circa 250 BC
On the website: http://www.mpoweruk.com/history.htm#250bc there is an explanation.
There is also a disclaimer suggesting that this artifact was in fact a scroll-case and as the objects were plundered after the gulf war, we may never be able to find out just what they were or were used for!

It is my thought that the Chinese may have known something about electroplating?
There are some 1/2-size, gold-plated, bronze horses and carriages there.
Perhaps these were also electroplated?
The Chinese also invented the magnetic compass at about this time.

I finally caught the History Channel show about the Baghdad Battery, and here's the thing: it's total speculation, not fact. While we have no good reason to dismiss the possibility that the Persians could have invented a battery; all we really ever had so far were a few pottery shards, and a piece of iron and a piece of copper discovered in the area.

Some archeologists advanced a theory that the iron and copper could have been put into a pottery jar, and this filled with vinegar to make a battery. But we must not be fooled into thinking that the artist's conceptions are anything close to what was actually found. Other archeologists feel it was just a few ritual items and that there is no evidence whatsoever of the use of batteries.

Anything is possible, John, but just repeating assertions doesn't make them more true. You said the first time that they were chrome plated, and I replied that everything that is shiny isn't chrome plated. Is there any metallurgical analysis or metallography demonstrating that they are chromium or that they are electroplated?

I heard about the Baghdad Battery and how it was used to electroplate coins. How would I a 12th grade student do that?

The Baghdad Battery is a speculation, Rick. Nor have any electroplated coins been found from that era; they are speculation as well. But please see our FAQ, "Electroplating: How it Works", for instruction on electroplating of coins for a school science project.
