What is this metal?
asmi:
I would also try making a hydroxide of that metal (Me + H2SO4 -> MeSO4, MeSO4 + NaOH -> Me(OH)n). Many of them have distinct colors and physical properties, which may help to identify the metal.
Refrigerator:
I put a piece of the metal on an old blade, gave it a bunch of heat with my butane burner and only when it got super hot did i see the slightest lick greenish/lime/cyan colour.
So it's between zinc and antimony.
T3sl4co1l:
Salts have poor solubility in ethanol so that doesn't say much. Take a few grains and hold them in said flame; as they get orange hot, they should burst into green-blue flames. Only zinc does this, the temperature and color being diagnostic. (Cadmium is close, but has a different color, and its oxide is yellow. Zinc oxide is yellow when hot, quickly turning snow-white on cooling.)

Make sure you run the control experiment with just the old blade :)

Haha, I was just thinking the same thing. :)
The look and SG of antimony and zinc are pretty close (what, 6.75 vs. 7?), but my personal guess is zinc. :popcorn:
