From the Wikipedia Terms of Use: So, just put this link in the original post, and everything's fine: Zinc toxicity In fact, having it present...
Most metals can be toxic if they're converted into soluble form. Zinc is bad because it's quite reactive, and even very weak acids attack it. The...
Be sure to allow plenty of time for the coin to "dry off" after the xylene soak -- both xylene and acetone will attack the plastic of airtites. (A...
Ah, the infamous "Melthelegend", formerly known as "Mel-ko". She went inactive for a while, and I wondered if eBay had disciplined her for the AT...
Your condo association probably wouldn't approve of you keeping flammable liquids on your balcony, but it's probably marginally safer than keeping...
I think silver has taken off more than enough at this point. Time for it to start putting some back on.
Once again the conservative sandwich-heavy portfolio pays off for the hungry investor!
It's possible that this is what they mean, but it seems extremely unlikely. The discussion I've seen centers on the notion that alloying .999 down...
1. "Unique" means "the only one of its kind". You can't be "more unique" or "less unique"; either you are or you aren't. 2. Why did the 1794...
Okay, I think I see it now. When I'm at home I'll try highlighting the relevant features in Photoshop and posting the result here, just to make...
Rats, I bid conservatively on a couple of silver auctions last night and didn't land any of them. If I'd only known... but then others would've...
This is a good time to go back and look at those sites, and see if that's what they really say. (I'd like to take a look myself, if you feel like...
So, was Detecto pointing out a threadjack, or asking for a threadjack? :)
1) When do you "know enough" that you no longer benefit from the opinions of others? 2) How can you tell when you "know enough", as opposed to...
Found a small pile of change in the reject slot at the grocery-store CoinStar this evening. A few chewed-up Zincolns, two copper cents, a quarter...
I was mostly going by the EMF table. Aluminum's a lot more reactive than even zinc; if not for that oxide coating, it would displace hydrogen from...
Most of the PMs are resistant -- gold, platinum, iridium, rhodium, palladium. Silver's sort of a historic outlier -- it's not all that rare, but...
Someone probably ground down the rim, removing the copper layer and exposing the zinc core, which would look silvery.
You're probably thinking of GOLD as the metal that's resistant to chemical attack. Silver's not as reactive as copper, but it's still reactive...
That was my first reaction, too, but reread the comment. He's pointing out that sometimes circumstances prevent you from canceling the scheduled...
