Himalayan salt often found in your Natural Salt Rock Lamps, is rock salt also known as Halite, mined from the Punjab Region of Pakistan.
The salt often has a pinkish hue due to mineral impurities. It is primarily used as a as table salt, but is also used as a material for cooking and food presentation, decorative lamps, and spa treatments.
The salt is reported with claims that it benefits health, but no clinical evidence exists.
Geology of Himalayan Salt: Where The Salt Rock Lamps Come From
Himalayan salt is mined from the Salt Range mountains. This is known as the southern edge of a fold-and-thrust belt that is to the south of the Himalayas. Also known as the Pothohar Plateau.
Himalayan salt comes from a highly Faulted and Folded thick layer of Ediacaran to early Cambrian evaporites. These evaporites come to form the Salt Range Formation.
The notorious geological formation consists of crystalline halite intertwined with potash salts.
The crystalline halite is composed on top by gypsiferous marl and has imposed beds of dolomite and gypsum with occasional seams of oil shale.
These strata and the overlying Cambrian to Eocene sedimentary rocks have been pushed down southward over younger sedimentary rocks. These rocks have then eroded to create the Salt Range.
Himalayan salt is sometimes marketed as “Jurassic Sea Salt”, this salt precipitated in subsiding rift basins along the edge of Gondwanaland much earlier, between 600 and 540 million years ago.
Of note, 145-199 Million years ago, the Jurassic Period was present/took place.
Natural Himalayan salt lamps have history
The initial records of mining are from the Janjua people. The time period of these records dates back to be in the 1200s. Himalayan salt is mostly mined at the Khewra Salt Mine in Khewra, Jhelum District, Punjab.
This Punjab region is located in the foothills of the Salt Range hill system in the Punjab province of the Pakistan to the Indo-Gangetic Plain.
Himalayan natural Lamps: Their Composition
Himalayan salt is chemically familiar to our everyday table salt. Some salts mined in the Himalayas are of course, far from suitable for use as food or industrial use.
This salt is only suitable for industrial use when undergoing purification due to the inherent impurities.
The salt crystals from this region have an off-white to transparent color, while impurities in some veins of salt give it a pink, reddish, or beet-red color.
Reliable analysis shows the main content of Himalayan salt to be about 96% sodium chloride, with the remaining amounts consisting of typical minerals, most in minute quantity.
Himalayan salt is nutritionally similar to common table salt but it lacks the beneficial iodine added to commercial iodised table salt.
Salt found in lamps: everyday uses
Himalayan salt most commonly, is used to flavor our food. It is recognized by its distinctive pink hue, a fabled misconception that it is healthier than common table salt.
Unfortunately, scientific evidence is lacking mainly to marketing costs, pink Himalayan salt is up to 20 times more expensive than sea salt.
Whole chunks of salt are used as serving dishes, baking stones, and griddles.In the United States, the Food and Drug Administration about marketing the salt as a dietary supplement. This is because claims are hard to come by with empiric scientific evidence.
Natural Himalayan Salt Lamps are used in spas as decoration!
