Owl Salt Lamp is made from Natural Rock Salt. This is the common name for the mineral "halite". Its chemical formula is NaCl.
what is rock salt?
This is the common name for the mineral "halite". Its chemical formula is NaCl. You might know this substance as table salt. and... Actually, rock salt is not K2SO4; it is NaCl. It can have impurities of gypsum (CaSO4) and sylvite (KCl) but it is very rare to find potassium sulfate as a mineral, although occasionally polyhalite (K2Ca2Mg(SO4)4.2H2O) is found associated with rock salt deposits.
how is it formed?
It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions.
where does it form?
One finds rock salt deposits ringing dry lake beds, inland marginal seas, and enclosed bays and estuaries in arid regions of the world. At various times in the geologic past, very large bodies of water (such as the Mediterranean Sea and an old ocean that sat where the Atlantic Ocean sits now) also evaporated and made enormous deposits of rock salt. These deposits were later burried by marine sediments, but since halite is less dense than the materials that make up the overlying sediments, the salt beds often "punched up" through the sediments to create dome-like structures. These are now mostly burried by additional sediments.
what is it used for?
Table salt is essential for human life. A large amount of the comercially mined rock salt is prepared for human consumption. Rock salt is also applied to road beds in cold climates to help reduce the freezing point of water on the road, thereby allowing it to not freeze-over at 0 deg. C (although I have no first-hand knowledge of this since I live in Hawaii).
why is it important?
As I mentioned above, Table salt is essential for human life.
In addition, the formation of Rock Salt deposits from the world's oceans is the major mechanism through which the Ocean's can regulate their NaCl. content, thereby not becoming "overly" salty.
Salt formations are also important in the rock record because they form one of the most important "traps" for petroleum in the crust. Geologists often use a variety of techniques to try and locate salt domes in the subsurface when they are exploring for new oil and gas resources.
Scientific studies proves that salt crystal lamps can create a healthy environment around you.
In nature Negative Ions are created by means of wind, sunlight, surf, waterfalls and rainstorms. Generally, a negative ion is an electronically charged molecule made up of oxygen. A positive ion in the air is a molecule that has lost its electrons through process of air pollution. In fresh country air we find up to 4000 negative ions per cubic centimeter, the size of a sugar cube. Near strong surf or close to a waterfall up to 10,000 negative ions can be found, however the number of negative ions in major capital cities at rush hour does not event reach 100.
The impact of ion is powerfull. Originally, it was found to speed recovery in burn or asthma patients, but was later discovered to affect serotonin levels in the bloodstream, stablize alpha rhythms and to positively impact our reactions to sensory stimuli.
Ionised air also substantially reduces the number of airborne bacteria indoors. Dr. Albert p. Krueger, a microbiologist and experimental pathologist at the University of California, found that an astonishing small quantity of negative ions could kill becteria and quidkly take them out to the air so they were less likely to infect people.
Even though they are not a medical device, Salt Crystal Lamps, by emitting negative ions, significantly reduce a myriad of indoor air pollutants. Negative ions have known benefits, and may provide relief from sinus, migraine headaches allergies and hay fever, reduce the severtiy of asthma attacks, enhance the immune system, increase alertness, increase work productivity and concentration, increase lungs capacity and reduce susceptibly to colds and flu.
