Evaporate the water - Salins-les-Bains

Operational up to the 1960-ies

 

From the 8th century to 1962, the Great Saltowrks of Salins-les-Bains has used natural salty waters as raw material to make salt. The presence of salty waters in Salins-les-Bains is explained by the existence of a sea, which covered Jura 210 millions years ago. The salt remaining after the evaporation of this prehistoric sea became a rock, called rock salt, lying today at 246 meters depth. The rainwaters infiltrating the underground became salty through contact with rock salt and the, by pressure, rose up naturally on surface to give birth to salty springs.

 

The salt, called "white gold", was obtained by evaporation, using an artificial source of heat (wood, and from the 19th century coal).
