Salt lamps present a wonderful fusion of individualist style and function. The warm soft glow that eminates from the salt is, for many, a great source of therapy. The salt lamp, unique as a fingerprint and manufactured by hand would be a focal point in any therapy room or in the home. Why use a Himalayan rock salt lamp? Rock salt lamps are used for indoor illumination. Electrical appliances, tobacco smoke and inadequate ventilation increase the consideration of positively charged ions in the air. Rock salt lamps discharge negatively changed ions thereby re-establishing the natural state of equilibrium.
