	A nice idea for a quiz. Could you please fix the stray capitals (the O in object) and every chemical element name (they are only capitalized when they are at the beginning of a sentence). You could also include alnico, billon, Britannia metal, constantan, duralumin, electrum, flint (iron and cerium), German silver, invar, tombac, Stainless steel can also be called Nichrome as a tradename. Pinchbeck is another alloy of copper and zinc. Lead and tin can also be called terne.

	Sproutcm, I've fixed the O in object. The elements aren't in sentances, so I think the capitalization can stand. I was going to add more, but I don't thin they're widely known enough. There are already two that fewer than five percent get, and that means practically nobody gets it on their first try.
