Candle flame. Burning candle seen with a light pattern. A candle consists of a vertical cylinder of wax,such as tallow or paraffin wax,with a central fibrous wick. A flame applied to the end of the wick produces a luminous flame which melts the wax,providing more fuel for the flame. The wick is treated with a substance such as alum so that it carbonizes but does not rapidly burn out | |
