Using your Nataly's Exquisite Aged Green Ceramic Table Lamp is easy. Just plug it into a 110 - volt outlet and switch it on using the 3 - way socket. It comes with one TYPE A bulb, and you can replace it with a 150 - watt bulb when needed. When cleaning the lamp, use a soft, dry cloth to gently wipe the ceramic base and the brass accents. For the white linen shade, a soft brush can be used to remove dust. Be careful not to get the lamp wet as it has steel and glass parts. Also, keep in mind that due to the natural variation in the fired glaze, each lamp is unique. And because it contains nickel, follow the California Prop 65 warning and avoid direct and long - term contact with the chemicals.
