These effusion lamps are wonderful to fragrance your home. The fuel is alcohol based. After you start your fire and the burner gets hot, you blow out the flame and it just somehow burns internally. It's one of those magical things that I don't quite understand, but I do know it works. If you need the fuel, I have a very good price on lamp avenue fuel in my store. All the easy fusion lamps are the same no matter the brand name. They all work the same way and one is just as beautiful as the next note. 39
