Quick Summary

iodized salt — iodized salt Iodized table salt (left) and non-iodized sea salt (right).

Sea salt is a type of salt derived from seawater, primarily composed of sodium chloride along with other salts. It has been harvested for millennia, mainly through solar evaporation.12

Historically, sea salt production has been a significant industry in coastal regions, particularly around the Mediterranean Sea. Modern operations continue this practice, with large-scale production facilities in places like Colombia. Beyond sodium chloride, seawater is also a source for extracting other valuable minerals such as bromine and magnesium.2

While common salt (also sodium chloride) is essential for health and industry, sea salt is specifically used in cooking.31

History
…for a very long time: sea salt, industrial by-products, and oils were first employed. Selective control of broad-leaved weeds in fields of cereal crops was discovered in France in the late 1800s, and this practice soon spread throughout Europe. Sulfates and nitrates of copper and iron were used, and sulfuric…
