Contemporary salt pans on the island of Lanzarote.
Salt pans are large shallow open pans used to evaporate brine for the production of salt. They are usually found on the coast, where there is a steady supply of brine.

Lanzarote, a Spanish island, is the easternmost of the Canary Islands, in the Atlantic Ocean ca. ... Brine is water saturated or nearly saturated with salt. ... A magnified crystal of a salt (halite/sodium chloride) In chemistry, a salt is any ionic compound composed of positively charged cations and negatively charged anions so that the product is neutral and without a net charge. ...
Earliest examples date back to prehistoric times and the pans were made of ceramics known as briquetage. Later examples were made from iron. This change coincided with a change from wood to coal for the purpose of heating the brine. Brine would be pumped into the pans, and concentrated by the heat of the fire burning underneath. As crystals of salt formed these would be raked out and more brine added. In warmer climates no additional heat would be supplied, the sun's heat being sufficient to evaporate off the brine.

Abandoned salt pans are a major feature of the southwest coast of Taiwan.
In chemistry the term salt is given to a compound formed by substituting the hydrogen of an acid by a metal or a radical acting as a metal, or, what comes to the same thing, by eliminating the elements of water between an acid and a base (see Acid; Chemistry).
The Antrim salt was discovered in 1850 during a search for coal: one of the beds at Duncrue mine has a thickness of 80 ft. Important deposits of rocksalt occur in the Keuper at Berchtesgaden, in the Bavarian Alps; at Hall in Tirol and at Hallein, Hallstatt, Ischl and Aussee in the Salzkammergut in Austria.
Salt often occurs in association with petroleum and natural gas, and extensive beds were discovered in the Wyoming valley in boring for petroleum.
Such pans are often several yards in length, and may contain one large flue, or several small ones, according to the work desired; but this form of apparatus is expensive to build, and difficult to keep in repair.
The water is evaporated, and the solid matter is delivered into the pit or wagon (E) at the lower end of the furnace, in a dry and calcined state.
The pan is generally heated by steam coils within it, or by a steam jacket, or by both.
