Why do some candles burn much longer than others?

    Wick size is the primary factor determining candle-burning rate. The big wick delivers more fuel to the burning flame. A candle is like a cylinder of solid fuel — paraffin wax — that surrounds a wick. Bringing a lit match to a wick melts and then vaporizes the wax coating the wick. The wax vapor combines with oxygen, and burns. Wax is the most important ingredient that makes a candle burn faster. Soft wax has a higher oil content and lower melt temperature; therefore, it burns faster. Typically, candles in jars have soft wax, and pillar candles have hard wax. The longest burning candles are pillar candles made of a blend of beeswax and paraffin.
