    Zones in a candle flame The interior of the luminous zone can be much hotter, beyond 1,500 °C (2,730 °F). [3] Color and temperature of a flame are dependent on the type of fuel involved in the combustion. For example, when a lighter is held to a candle, the applied heat causes the fuel molecules in the candle wax to vaporize.

  3. Pyrotechnic colorant - Wikipedia

    en.wikipedia.org/wiki/Pyrotechnic_colorant

    A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. These are used to create the colors in pyrotechnic compositions like fireworks and colored fires. The color-producing species are usually created from other chemicals during the reaction.

    en.wikipedia.org/wiki/Colored_fire

    Color enhancers (usually chlorine donors) are frequently added too, the most common of which is polyvinyl chloride. A practical use of colored fire is the flame test , where metal cations are tested by placing the sample in a flame and analyzing the color produced.

  5. Combustibility and flammability - Wikipedia

    en.wikipedia.org/wiki/Combustibility_and...

    A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.

    Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. [3] Fire, in its most common form, has the potential to result in conflagration, which can lead to physical damage, which can be permanent, through burning. Fire is a significant process that influences ecological ...

    Other colors of flame such as orange and yellow are possible depending on the mixture of gases formed in the colon. In 1999, author Jim Dawson observed that fart lighting has been a novelty practice primarily among young men or college students for decades but is discouraged for its potential for causing harm.

  9. Luminous flame - Wikipedia

    en.wikipedia.org/wiki/Luminous_flame

    A luminous flame is a burning flame which is brightly visible. Much of its output is in the form of visible light , as well as heat or light in the non-visible wavelengths. An early study of flame luminosity was conducted by Michael Faraday and became part of his series of Royal Institution Christmas Lectures , The Chemical History of a Candle .
