Mercury

Mercurius
Formula:
Hg
Colour:
Tin white
Lustre:
Metallic
Specific Gravity:
13.596
Crystal System:
Trigonal
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.

Other Information

Special Storage/
Display Requirements:
Mercury should be coated with a plastic material or placed in a sealed container since the mercury will vaporize over time.
Health Risks:
Contains mercury - always wash hands after handling. Avoid inhaling dust of associated rock or matrix when handling or breaking. Never lick or ingest. Vaporizes with toxic vapours, do not inhale vapours and store under cover.
