Homefire,
I agree, don't mess with something you know little about.
I like to think I know a bit about Mercury.
Mercury:
Formula:
Hg
System: Trigonal Colour: Tin white
Lustre: Metallic
Name: After the Roman messenger of the gods, Mercurius.
Mercury is officially classed as a mineral species for historical reasons, and also because it is distinctive in its chemical and physical properties. However, because it occurs as a liquid, it does not satisfy the normal criteria to be a valid mineral. It crystallizes at -40 degrees celsius, at which point is forms rhombohedral crystals. It is usually found as small isolated drops associated with cinnabar, but it can also be found as large liquid masses in rock cavities. Mercury is often found, along with cinnabar and other Hg minerals, as a precipitate from hot springs and in volcanic regions. Because of its rarity, it is not often used as an ore of mercury.
