Salt is essential to health as a source of sodium; blood and all other physiological fluids are dilute salt solutions. One of the most widely employed materials of the chemical industry, it is used in manufacturing chlorine, caustic soda, sodium carbonate, bicarbonate of soda, soap, and chlorine bleach, as well as in ceramic glazes, metallurgy, food preservation, curing of hides, road de-icing, water softening, photography, and many consumer products, including mineral waters, mouthwashes, and table salt itself. It is mined, extracted from seawater, and obtained from dry salt lakes called pans. See also halite.
