In contrast to electrical lighting or a flashlight, a candle is a natural source of light. It provides warm, pleasant and especially lively light. It does not provide as much light as a modern light bulb, but on the other hand it creates much more of an atmosphere.
Candles are made of two essential parts:
One is the candle body, which is made for example from paraffin, stearin or beeswax, and the other one is the wick. Wicks are made of multiple-woven cotton and are usually covered with a thin wax layer. This layer burns downward from the tip of the wick after being lit.
The resulting heat melts the wax in the upper part of the candle. The wick is able to absorb the liquid wax and transports it up to its tip, where it burns as a bright flame together with oxygen. When the candle has burnt down and there is no more wax, the wick extinguishes.
