The melting point of sodium chloride, commonly referred to as table salt, at standard pressure is 801 degrees Celsius. This represents the phase transition from solid, crystalline salt to a liquid. Liquid salt turns to a gas, or boil, at 1,413 degrees Celsius.
Solid salt is found abundantly throughout the surface of the Earth and is represented significantly in the salinity of the world's oceans. Salt comes from a variety of sources, including mining rock salt and desalinating ocean water. Approximately 270 million metric tons of salt are produced worldwide annually; China leads globally with 60 million metric tons produced.
