Looking for a way to discolor nickel
++++
Hello.
I have an older (1970's vintage) electric guitar. I am updating the hardware, but I would like the hardware to retain a "vintage" appearance. The older guitras all had nickel-plated steel hardware (most newer guitars have chrome-plated hardware). I am looking for a way to prematurely age the new nickel-plated hardware I have purchased for this guitar. I have seen vintage instruments with original discolored nickel hardware, and it really adds to the appearance. I know that letting sterling silver contact cooked egg yolks will hasten the tarnishing process (by adding a disproportionate amount of sulphur to its environment); does the same hold true for nickel?
Many thanks in advance for a reply.

The chrome plating on top of the nickel, if present, must be stripped first. Then the nickel will tarnish and yellow by itself. I don't think eggs will speed it up, but no harm trying.

If the nickel is allowed to be exposed tothe atmosphere, it will naturally tarnish. This can be enhanced by exposing it it an atmosphere rich in either hydrogen sulphide or sulphur dioxide. Both gases will produce a dark grey/black thin coating of nickel sulphide. Eggs may well do the trick, but could take some time.
