Sea salt

Sea salt is a crystalline mineral obtained from the evaporation of seawater. Primarily composed of sodium chloride (NaCl), it also contains traces of other minerals like magnesium, calcium, and potassium. Crystallizations can form cubic or pyramidal structures, often with an opalescent sheen. Historically, it has been used as a preservative, currency, and ritual tool in ancient cultures, from the Celts to the Egyptians.
