HemingWeigh Natural Himalayan Salt Lamp Himalayan salt lamp emits number of negative ions into surrounding atmosphere when it is heated by an external source of electric or candles. The heat produced from the lamp breaks down Na CL Sodium Chloride in a process called ionization. This process is enhanced by the natural process of NACL resulting in the production of negative ions which eliminate the positive ions which are present in our environment, produced by computers, refrigerators, televisions and more. Thus these lamps make the air clean, fresh and healthy to live in.Natural salt crystal is found in ancient evaporated sea beds underneath great mountain masses, such as the Himalayas, where it has been compressed over time to form solid salt rock, with all the minerals structurally intact. Crafted Salt Lamps These are the most common shapes of the salt lamps we produce. In this category, Lamps are crafted with the machines by experienced crafters. So this is the why that most of the lamps come in the same size and shape comparing to natural shapes. Although the machines used are not digital, an experienced crafter is needed to shape them in a regular size. Here some of the shapes are displayed. If you are looking for any other which is not here, please do not hesitate to contact us. Our accuracy is up to 90% in shapes and weight categories. Benefits: Crystal Salt Lamps emit negative Ions to their surroundings. The ionization helps combat many of the harsh elements that assail our bodies, causing us to feel unwell. Placement of our salt lamp in an area that one uses frequently can help balance the body, boost our immune system and give back lost energy. Negative ions purify the air, reducing the effects of: Dust, Bacteria, Pet Dander, Odor, Allergies, Asthma, Sinus, Fatigue and even Colds. May also relieve symptoms of Anxiety and Insomnia.
