Subject: RE: Yay science -- could leftover chlorine on my skin be causing "gold smudge" under my jewelry? Originally posted by Miles around Midtown
I hit the pool this morning, showered and got ready for work. I put on a lovely bracelet that I assume is silver, aluminum or nickel coated.
A few hours later I noticed I had "gold smudge" (when your skin turns green or black from cheap gold) on my arm. I wore the bracelet yesterday and didn't get the smudge, but I didn't swim yesterday, either. Also, my wedding ring (white gold) doesn't cause my fingers to turn colors, and my cheap silver necklace (not sure of the exact metal) didn't cause my neck to turn colors.
Google seems to suggest that the leftover chlorine on my skin could be causing this. Has anyone else had this problem, and what did you do to solve it? Does it happen with some metals and not others?
Thanks!
Actually where I currently work we do refining and processing of gold and platinum products.
Chlorine is a very reactive chemical.
What your jewelry is for sure I do not know, so that's where things get fuzzy. Different jewelry is alloyed differently, such as the white gold you have. There are different ways to make white gold however for the most part gold or white gold should not have a problem with the chlorine. Nickel is very slow to react with chlorine in a molten state, and I don't think you would see a reaction as a solid.
Silver jewelry on the other hand is made often by alloying in copper which does react with chlorine. Also some jewelry is silver coated, so a scratch in the silver will expose the base metal whatever that may be.
If you know specifically what you jewelry is I can tell you if you have any issues with chlorine.
