What is a candle?

A candle is a device for providing light or dispersing fragrance. The body of a candle is comprised of a solid fuel source, usually paraffin wax. A wick runs through the center of the body of the candle from the bottom, extending out of the top. The wick, which acts as a fuel pump when the candle is burning, is generally made of cotton fibers that have been braided together. You can obtain candles in a variety of styles. The main types of candle are : Taper, Formal, Pillar, Column, Container and Votive.
Inside a candle is a string like material that helps keep the flame going. Going a layer out is nothing but wax.
