Wikipedia
Sea salt is salt produced from the evaporation of seawater, rather than by being extracted from sedimentary deposits. It is used in cooking and cosmetics. It is also called bay salt or solar salt. Like mineral salt, production of sea salt has been dated to prehistoric times. Some cooks believe it tastes better than salt from mines. However, there is little or no health benefit to using sea salt over other forms of sodium chloride salts.
