 Candle - Unipedia   (Site not responding. Last check: 2007-10-08)
A candle is a light source usually consisting of an internal wick which rises through the center of a column of solid fuel.
Today, candles are usually used for their aesthetic value, particularly to set a soft, warm, or romantic ambience, and for emergency lighting during electrical power failures.
Candles can be made of paraffin (a byproduct of oil refining), stearin (now produced almost exclusively from palm waxes), beeswax (a by product of honey collection), some plant waxes (generally palm, carnuba, bayberry, or soy), or tallow (a rarely used byproduct of beef fat rendering).

John Clayton, in an extract from a letter in the "Philosophical Transactions" for 1735, calls gas the "spirit" of coal; and discovered its inflammability by an accident.
This "spirit" happened to catch fire, by coming in contact with a candle, as it escaped from a fracture in one of his distillatory vessels.
In this year, 1817, at the three stations belonging to the Chartered Gas Company, 25 chaldron (24 m³) of coal were daily carbonized, producing 300,000 cubic feet (8,500 m³) of gas, which was equal to the supply of 75,000 Argand lamps, each yielding the light of six candles.

A wick lamp is a simple type of kerosene lamp which works in a similar way to a candle.
The draft carries more air (oxygen) past the flame, helping to produce a brighter light than would be produced by an open flame.
This type of lamp produces only a dim yellow light and is not much brighter than a candle.

His was a story of a self-made man, who elevated himself from humble beginnings on a farm near Wickliffe, Ohio, to a prominent citizen of the Cleveland community.
Brush's arc light was more satisfactory than the candle of Pavel Yablochkov of Russia because the Brush light burned twice as long as the Yablochkov candle.
The arc light preceded Edison's incandescent light bulb in commercial use and was suited to applications where a bright light was needed, such as street lights and lighting in commercial and public buildings.
