Hardness, Cleavage, Fracture, Tenacity, Special Gravity

Tenacity may be tough as in jade, flexible as in gypsum, elastic as in muscovite, sectile as in gypsum, or malleable as in copper. Special Gravity The specific gravity of a mineral represents its weight compared to the weight of an equal volume of pure water. Thus, a mineral with a specific gravity of 5 is five times as heavy as water.
