Rock Salt Halite Mineral
Rock salt is composed of the mineral halite which is sodium chloride, or NaCl. Samples of rock salt can be white, clear, blue, pink, yellow, red and purple. On the Mohs Hardness Scale of 1 to 10, rock salt is a 2.5, which means it is a very soft mineral that is approximately the same hardness as your fingernail. You can scratch salt with a copper penny, pocketknife or steel file. Rock salt crystals have a glassy luster, white streak and are salty to taste.
An information card with details on the mineral formation, characteristics, and uses is included. Typical samples sizes are generally 1-2 inches in length or width but can vary based on availability and natural crystal shape.
