From where does the salt come?

Sea salt

It is in the oceans, most of the salt is. Man has since ancient times downloaded salt from there. A method for the production of sea salt, used for many centuries, are letting seawater evaporate into a kind of shallow ponds, called saline. It puts more saline in a row after another, leading the water from saline to saline. For each saline is the salinity of the water higher than the last. As the water evaporates faster is sold it is, the process goes faster like this than if we would let the water evaporate away in just a saline. It harvests salt around once a year. After harvesting, wash the salt Monday, dries it and strainers in order to obtain different grain sizes. In places where the climate is sufficiently warm and dry for the evaporation of this kind sometimes sea salt is produced by taking the sea salt in large pans and gently warm them from below so that the water evaporates. So produced, for example, the good Jozo Maldon Sea Salt produced in the village of Maldon, England.

Rock salt

Rock salt mined in the salt mines. Salt depots in the underground, the rest of the lost sea. Sea water is evaporated and the salt has been 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.

mines where salt is lost due to the geological composition ideal locations for perishable things, which can damage the surface. The abandoned mines are now archive, stamp collections, furs and petroleum products. For example. Some mines have also become popular tourist destinations. Europe's largest salt mine, Wieliczka mine, located outside Krakow in Poland. It has over the years developed into a fascinating labyrinth of passageways in the 12-13 mil, three Catholic chapel, a sanatorium and thousands of other mine rooms. Because the acoustics are fantastic has sometimes concerts down in the mine. Wieliczka mine is on Unesco World Heritage list.

Vacuum Salt

Vacuum salt is rock salt that has been refined. It pumps into clean water in the large salt deposits and dissolves the salt to a salt solution. This brine is purified from contaminants with special chemicals and then you let the water boil away, either under pressure or under vacuum (negative pressure). It should then be a salt that is> 99.9% pure sodium chloride. With the help of boiling, you can also control the size of salt grains, so as to obtain rough-grained or fine-grained salt, depending on what you want it to. One way used to break the rock salt is by drilling. The product you get then is just the vacuum salt. The remedy is to drill down into the salt layer in the rock and blow down water. The salt dissolves in water and taking up the solution through a tube. When we in Sweden talking about vacuum salt, we mean mostly rock salt, which is broken in this way. Since the vacuum salt is so pure, it is very useful. It has the food, chemical industry, softening, farming, fishing industry and much, much more.
