Commercially Available

When rock salt is commercially available, it is not made of the natural salt crystals, but rather, from the salt brine that is allowed to evaporate. This evaporated brine is then used to form commercial rock salt. This is the variety that, as an example, is commonly used to salt roads and driveways with; though its uses are numerous. Rock salt not only helps keep roads and paths free of snow, but can also be used to melt ice as well.

The lakes that it forms in have very high salt content and evaporate during the hot, dry summer months. When the evaporation occurs, salt forms on the lake-shores and the remaining salt is used by humans. Perhaps interestingly so, rock salt occurs in non-arid areas as well. When these deposits occur, they are underground and are normally mined by drilling into the salt layer, pouring hot water into the deposits to dissolve them and then pumping the briny, salty water out. Once the impurities have finally evaporated, what remains is salt that ends up being harvested for use.

Another place that halite forms is in what is known as salt springs, where the salt is naturally pumped from the water and allowed to evaporate. However, the most interesting occurrence of rock salt is in some of the underground deposits in the Southern United States; because these deposits are pushed out through underground forces that cause the salt to form domes. Not only are these domes extremely impressive and unique geological formations, they are also very important for salt miners.

It is quite possible to create artificial rock salt. In fact, some of the largest and best specimens of Halite are actually not produced naturally at all. Instead, a solution of saltwater is created and allowed to evaporate. Once the Bang Bros discount solution has evaporated, crystals will start to grow in what is commonly known as a hopper shape. Hopper-shaped crystals are actually interesting, cube-shaped crystalline structures that grow in patterns that are very pleasing to the eye.

While natural rock salt is more expensive than artificial, that is simply because of how long natural rock salt takes to form and how it is mined. Artificial rock salt grows more quickly and because its growth is carefully controlled, it is less likely to contain impurities or imperfections. A perfect, colorless piece of artificial rock salt can resemble an interesting piece of ice that has formed in an unusual manner. Both natural and artificial rock salt can be used interchangeably; their properties are so similar to one another that it can sometimes be impossible to tell the two apart.


Rock Salt

Available in every color of the rainbow, along with grey and clear, Halite is the name of rock salt; which is the natural form of salt. Extremely common and well-known by most people, with numerous uses, rock salt is found in oceans and salt lakes, where it grows in very large and solid masses. Despite the fact that it can be found in nearly every color other than black -and is occasionally even multi-colored- the crystals can be stunningly beautiful, rock salt cannot be used for ornamental purposes whatsoever. Something quite interesting about rock salt is that impurities, crystal defects, bacteria and algae are the reasons for the color variance.

Rock salt has various uses; the most well-known is that it is a component in making ice cream, regardless of whether an ice cream maker is used or not. Rock salt is used in making ice cream because it helps make ice cream become colder than it would have been under other circumstances. Another well-known use is that it can be used during the winter to clear driveways and roads.

Large, interesting chunks of salt can even be hollowed out and shaped into interesting lamps; however one must be careful when they are creating salt lamps, as it can be very caustic.One of its most interesting uses is as a weed killer: salt dries out plants and prevents them from growing where they are not wanted. However, one must be careful when using it as a weedicide, as it can completely stop plants from growing if too much is used at any given time.
