Candles have been around till perhaps the dawn of civilisation. It has an ignitable wick that is embedded in a flammable substance that is first melted to put the wick in place and then hardened to give a definitive shape to it. This substance may be tallow, microcrystalline wax, beeswax, or a gel mix of polymer and mineral oil or even plant waxes from vegetation like the palm, carnauba, bayberry and soybean. The size of the flame is typically controlled by the size of the wick.
Production process of candles is almost the same, regardless of the substance used. The fuel is melted by indirect application of heat. The melted wax is poured into a mould and the wick repeatedly immersed in it till it has hardened wax sticking to it. The remaining wax solidifies around the wick. To have a touch of the traditional, fragrance oils are added as well as dyes to for coloured candles.
The principle behind the working of candles is rather simple. Once the wick is lit by a flame, it melts and vaporizers a small amount of fuel which in this case is the wax. This vaporised fuel then combines with oxygen in the air to produce a constant flame.
Candles have over the ages been used for a variety of purposes. The first if course is for illumination. Wick lamps came much later. Even today, the common source of light in areas without electricity is candles. Apart from this, scented candles change the very ambience of an area, heightening the senses and lending an almost religious aura to a place. In olden times, candles were also used to set time. Careful calibrations were made on a candle that denoted specific hours of a day, calculated by the rate of burn down of the wax.
