Why Does A Candle Keep Burning. Lighting a candle for just a short period (less than an hour) can prevent the wax from melting evenly, leading to tunnelling. The heat of the flame produces an updraught of air that draws the flame into its familiar shape. In zero gravity there is no ‘up’ and a flame forms a sphere. The wax evaporates into the atmosphere as the reaction to heat and flame turns it from a solid, to a liquid, to a gas. In a burning candle, wax is drawn up the wick by capillary action and evaporates, so what is burned is a gas. Test your knowledge about the science of candle burning, the role of waxes and wicks, and the factors affecting how a candle burns. Finally, and most importantly, is safety. If you try to light a lump of wax you can melt the wax but that is just about all that happens. So why does a candle need a wick? A candle that burns longer fills your room with its delightful scent for more hours. The candle uses the wax as fuel to keep the flame burning, and when the fuel (wax) has completely evaporated, it will no longer burn.
