If you're using this bulb under an Aladdin mantle, please follow these instructions BEFORE using the bulb:
You'll need to burn the blue coating off your new Aladdin mantle before you put it over this bulb. To do this, set your lamp's gallery on a table and put the mantle on the gallery. Light a match and very carefully, touch the flame to the edge of the blue coating. Do NOT touch the match itself to the mantle, or it could break. The mantle will catch fire and the flame could be up to 6-10" high (so don't be startled by it). Once the blue coating is burned off, the fire will go out by itself. Once your mantle cools, it is now ready to carefully place over the bulb in your lamp. When turned on, the mantle will glow just as if you are using a wick.
