ABSTRACT:
The present invention provides methods and apparatus for controlling a flame. One embodiment comprises a reservoir for a flame-fueling liquid, a wick, and a collar surrounding the wick. The first end of the wick is within the reservoir and a flame-bearing end is above the first end. Flame-fueling liquid is supplied to the reservoir and is communicated up the wick to fuel a flame emanating from the flame-bearing end of the wick. The collar is slidable along a vertical axis between a first and second position. In the first position, the top of the collar is located above the flame-bearing end of the wick to block the flow of air from reaching the wick. In the second position, the top of the collar is located blow the flame-bearing end of the wick, such that it does not substantially block the flow of air from reaching the wick.
