Salt - Occurrence | Britannica

Salt - Salt - Occurrence: Though the material that gives seawater its salty flavour is composed of many substances, sodium chloride, or common salt, is by far the predominant compound. On the assumption that 1 gallon (about 4 litres) of seawater contains 0.231 pound (about 105 grams) of salt and that rock salt on the average is 2.17 times as dense as water, it has been estimated that if the ...

Salt production method - The Salt Industry Center of Japan

Open iron kettles were replaced by salt-kettles with a steam heating system. Studies began into vacuum evaporation. Circa 1950: Sloping salt-terraces were developed for salt concentrate production, replacing the channeled salt-terraces which had been in use for a long time. The vacuum evaporation method became the usual method for boiling down.
