Rock salt

Rock salt is lost in the salt mines. Salt depots in the underground, the rest of the lost sea. Sea water is evaporated and the salt has wrinkled into the bedrock when the earth's crust has moved. In some places they may have sold the stocks to be very deep. In Germany, for example, 1000 meters deep layers, and also in Poland and Denmark are large salt deposits. Before rock salt is mined, when it still remains below ground, it is customary to call it rock salt. Rock salt used for roads with salts for snow melting and as raw material for vacuum salt.
