Wax is a solidified substance that holds the wick in place and melts with the heat of the flame and thus supplies the fuel to keep the candle alight.

If you observe a lit candle burning that has a few specs of carbon (soot) in the puddle of melted wax, you will notice that the particle circulates toward the flame then away from it. This allows hot wax to melt more wax and keep the puddle large enough to feed the wick. The melted wax 'wicks' up the wick to feed the flame. The flame has a constant supply of hot wax to vaporize and feed the flame without consuming the wick. If the puddle of wax gets too deep it will flood the wick reducing the size of the flame and reducing the heat. Therefore the candle is a self-regulating source of light (or sometimes heat to keep food warm). When a log catches fire in a fireplace, the flames grow until the entire log is being consumed. Because the candle is self-regulating, it takes a much longer time to burn; and in fact at one time candles were used to keep time.

I think that candles are made of of wax because it is a slow burning substance. Using something fast burning would just be stupid! Candles are generally made to last, which is why they would be made out of something that burns slowly. Either that or they are made out of things that can have scents put in them

Cause if they make them out of paper they burn too fast
