| What is this metal? |

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.) Tim |
