Rock Salt

Rock salt is a type of salt that is extracted from underground salt mines or salt deposits formed by the evaporation of ancient seas. It is a naturally occurring mineral that is composed primarily of sodium chloride and other minerals such as calcium, potassium, and magnesium. Rock salt is commonly used in the maritime industry for de-icing and anti-icing purposes, especially in colder climates where ice formation on ships and ports can be a major safety hazard. It is also used as a preservative for fish and other seafood during transportation and storage.
