Himalayan Crystal Salt is highly hygroscopic, which means that it naturally attracts moisture from the air. With the lamp switched on, any moisture is consistently evaporated and does not have a chance to accumulate. However, if a globe goes or the lamp is left switched off, the moisture starts to accumulate, drip, create small pools of water and initiate a crystallization of the salt on the lamp and around the base. If a lamp is going to be switched off for an extended period (a few days or longer), it is recommended that the lamp is covered with an air tight bag. This will ensure that the lamp is sealed off from the moisture in the surrounding atmosphere, keeping it dry, and preventing the accumulation of moisture.
