Science project, part deux
Coworker showed me this. She said a test for anemia is to rub sterling silver on your hand or cheek. If it rubs off, you're anemic. I don't know about all that, but it's cool anyway.When I got home from work, I tested different metals on my hand. You can't really tell from the picture, but the lines are slightly different colors. Platinum is a very pale gray, white gold is a bluish-gray, and sterling is a greenish/goldish-gray.
Silver, gold and platinum alloys differ in composition (silver + copper = sterling; gold + nickel + zinc = white gold; platinum + iridium or rhodium or titanium = platinum alloy). I guess the different compositions make the lines different colors.
Paul said he didn't know why it happened, but he'd ask some of the biochem students he teaches in quant lab.

Me know why.... but me not going to tell you.
...love the socks!
So, do different metals mean different things? I have a platinum wedding band, but it doesn't leave a mark, exept on my wife's eye (kidding!).
I dig your bracelets. Kinda punkrock.
monstee: do you really know? because i dont, my advisor doesnt, and my whiney students dont either (taking biochem)
Yes, me really know.
And me not surprised you whinny students not know. Biochem? What wussies! Now if you had asked geologist or even better metallurgist....
...or even persons who been like in retail jewelry for years....
RAWRARARARARRWWRWRARR!
tell us already :p
i figure it has something to do with the added impurities, but thats about as far as i got.
