Pink Himalayan salt is a crystalline material that has a tendency to crystallize upon exposure to air. In the process of crystallization, the impurities found in sea water – dissolved minerals and other impurities that are not removed – are not trapped by the salt. Consequently, a flat, oily substance forms in its place, known as "his"hex".
The minerals found in the sea are imparted to the mineral salt by sea water, thus producing a long range of properties that can be found in this crystal. Himalayan salt contains up to six times more magnesium than table salt, or almost one-third of the amount found in saltpeter. It is a great conductor of electricity, and has been used since ancient times for surgical purposes. However, modern science has found a number of uses for this mineral, including pain relief, anti-bacterial, anti-fungal, astringent, and antiseptic.
Himalayan salt was first used for scientific experiments at the University of Washington in the 1950s. It showed very good results in reducing bacteria in water. One important use for Himalayan salt is in the production of cosmetic products, such as toothpaste and nail polish.
Himalayan salt has been used in China for a long time, and has even been a major part of the diet of the Chinese people. According to legend, the Chinese were so impressed with the results of Himalayan salt that they started referring to it as "puce", a light pink salt.
Most clinical research studies on Himalayan salt have focused on its antibacterial properties. It has proven to be especially useful against acne and other skin disorders. Pink Himalayan salt is a better antiseptic than iodine, and it resists the growth of bacteria that may cause acne.
When water is distilled using crystals water, it leaves behind a residue of crystal water, which can be found in contact lenses, laser, and disposable lenses. The crystals contained in crystal water are generally low in sodium, making it particularly beneficial in making contact lenses.
While the crystals are commonly used in contact lenses, they are also widely used in the manufacture of different types of glasses, such as water, thermochromic, and bistable glasses. This means that it is possible to make glasses that perform several functions in one device.
In addition to its antibacterial properties, Himalayan salt is also used in the creation of different shapes of glasses. For example, it is used in the creation of cylindrical, wine-glass-shaped, and even sand-glass-shaped glasses. Some of these glasses are used in the manufacture of restaurant glasses.
Hiss reduction, also known as hisschelite reduction, has been one of the most promising applications of Himalayan salt in recent years. Its effect on noise, which had been a problem with some types of lenses, has been improved considerably.
Glasses with the best hisschelite reduction usually have a number, called the "saltiness index", on them. The higher the saltiness index number is, the less noise there is, and vice versa.
Most modern lenses are made from glasses with high saltiness indexes. Because of this, most of the "white light" glasses we use are usually referred to as "high" hisschelite glasses.
This material is used in various applications. It is being used in the manufacture of laser lenses, as well as protective eye glasses, and other devices.
