The combustion from the candle proceeds in self-sustaining manner. Given that the wick of candle is lit, the warmth melts and ignites a little level of strong fuel (the wax), which vaporizes and brings together with oxygen during the air to sort a flame. The flame then melts the highest in the mass of strong gasoline, which moves upward in the wick by means Candles of capillary motion for being continually burnt, thus retaining a continuing flame.
