Does copper migrate through silver?


Today I removed my ACME silver plated cryo receptacle from more than 20 days' burn in through my refrigerator. I noticed the silver was more 'orange' in color, as if copper had mixed with it. Is this possible or just an optical illusion?

Crump, I have two oil refinery less than two miles from me!

Should I do something about the air quality in my apt? I've been concerned about that.

So much for Audiogon's lawyer out of place comment...
Psychianimal, I live in Houston so enough said about air quality as I have gotten to the point I don't trust air I can't see :-) Time for us both to move.....
Well, Lak was here this afternoon and he told me the silver had indeed discolored. We got our outlets in the same Dutch auction last December.

He had a good time listening to my "DJ TT on steroids", too!
I have also seen silver oxidize heavily at room temperature. It can be polished back to shiny though.
Psychicanimal,

I was very impressed with the sound and looks of your system. I'm amazed at how detailed your system is with all types of music--CDs and vinyl. Very impressive! :-)

Let me know when you have your rig set up in the new location, and I'll bring over the digital camera so that we can put your system online.
