Salt lamps are created by illuminating salt crystals with a low-watt light bulb. These light fixtures provide a relaxing atmosphere for any room and may cleanse the air of allergens or irritants. Salt lamps are available in a variety of sizes and styles in stores and online. They can also be created easily and inexpensively at home by inserting a lamp kit into a bowl of your choice and filling the bowl with salt crystals.
Choose a bowl for your salt lamp. Sturdy options include glass and metal.
Drill a hole in the side of the bowl large enough to thread the lamp cord through.
Place the portion of the lamp cord containing the light bulb socket inside the bowl and thread the cord through the hole in the bowl's side.
Screw the light bulb into the socket. Low wattage bulbs, such as seven to 15 watts, are best for this project to avoid overheating.
Plug in the lamp cord to make sure the bulb is working properly before adding salt.
Pour the rock salt gently into the bowl until the bowl is full and the light bulb is completely covered.
Turn on the salt lamp. Remove a small amount of salt or choose a bulb with a slightly higher wattage if the light does not shine through the salt as desired.
