The first step in making paraffin wax is to remove the oil (de-oiling or de-waxing) from the slack wax. The oil is separated by crystallization. Most commonly, the slack wax is heated, mixed with one or more solvents such as a ketone and then cooled. As it cools, wax crystallizes out of the solution, leaving only oil.
In early 19th-century America, spirits of turpentine was burned in lamps as a cheap alternative to whale oil. It produced a bright light but had a strong odour. [15] Camphine and burning fluid (a mix of alcohol and turpentine) served as the dominant lamp fuels replacing whale oil until the advent of kerosene, electric lights and gas lighting.
Kerosene can be used as an adhesive remover on hard-to-remove mucilage or adhesive left by stickers on a glass surface (such as in show windows of stores). [58] It can be used to remove candle wax that has dripped onto a glass surface; it is recommended that the excess wax be scraped off prior to applying kerosene via a soaked cloth or tissue ...
When the lamp is lit, the kerosene that the wick has absorbed burns and produces a clear, bright, yellow flame. As the kerosene burns, capillary action in the wick draws more kerosene up from the fuel tank. All kerosene flat-wick lamps use the dead-flame burner design, where the flame is fed cold air from below, and hot air exits above.
R. E. Dietz Co., Ltd. (formerly R. E. Dietz Company) is a lighting products manufacturer best known for its hot blast and cold blast kerosene lanterns. The company was founded in 1840 when its founder, 22-year-old Robert Edwin Dietz, purchased a lamp and oil business in Brooklyn, New York.
In 1915, during World War I, the Tilley company moved to Brent Street in Hendon, and began developing a kerosene pressure lamp. [12] In 1919, Tilley High-Pressure Gas Company started using kerosene as a fuel for lamps. [13] In the 1920s, Tilley company got a contract to supply lamps to railways, and made domestic lamps. [12]

The lamp consisted of a Geissler tube that was excited by a battery-powered Ruhmkorff induction coil; an early transformer capable of converting DC currents of low voltage into rapid high-voltage pulses. Initially the lamp generated white light by using a Geissler tube filled with carbon dioxide. However, the carbon dioxide tended to break down.
