candle

history of candle

candle can also be useful  to provide heat, or as a method of keeping time.

A candle is an ignitable wick embedded in wax or another flammable solid substance such as tallow that provides light, and in some cases, a fragrance.

it is also a religious and meditation important unit , it s flame and burning has special meanings in different cultures and religions .

when wax and oil was not famous in the world and some one had not found them people made torches by wood and clothes . after a while for more lasting light and burn they tried oil of animals on them . fire is holy in all cultures and countries , it is one of 3 life elements in world : water , soil , fire .

A candle manufacturer name is traditionally  a chandler. People invented various devices  to hold candles, from simple tabletop candle holders to elaborate chandeliers.

As the mass of solid fuel is melt and consuming, the candle becomes shorter. Portions of the wick that are not emitting vaporizing fuel are consuming in the flame.

For a candle to burn, a heat source (commonly a naked flame) is good to light the candles wick. which melts and vaporizes a small amount of fuel (the wax). Once vaporizing finishes, the fuel combines with oxygen in the atmosphere to ignite and form a constant flame.

This flame provides sufficient heat to keep the candle burning via a self-sustaining chain of events. the heat of the flame melts the top of the mass of solid fuel, the liquid fuel then moves upward through the wick via capillary action. and the liquefied fuel finally vaporizes to burn within the candle’s flame.

The incineration of the wick limits the exposed length of the wick

Thus maintaining a constant burning temperature and rate of fuel consumption. Some wicks or fitil require regular trimming with scissors (or a special wick trimmer) .usually to about one-quarter inch (~0.7 cm), to promote slower, steady burning, and also to prevent smoking. In early times, the wick needs to be trim quite frequently. Special candle-scissors , are useful for this purpose in the 20th century and were often combined with an extinguisher. In modern candles, the wick  construction is so that it curves over as it burns. This ensures that the end of the wick gets oxygen and is then consumed by fire a self-trimming wick .
