I have one salt lamp that does not sweat which is a really orange color. The one that is sweating is more of a whiter color. Does that have anything to do with it?
The sweat of the salt lamp can be of differing colors depending on the minerals in the salt. Some salt lamps are more white, others are more orange, and the sweat will match that. The color of the salt does not effect how much the salt lamp sweats. You can dry out your lamp by putting it in your oven at a very low temperature (150-175 degrees Fahrenheit) or by keeping it lit and away from open windows in damp weather.
