Added on 30 September, 2007 DescriptionA candle flame is composed of four distinct layers, visible to the naked eye. Each layer is a distinct color: white, light yellow, dark red (or brown or orange), and blue. At the base is a relatively cool blue layer (800° C), where the material of the burning candle is in contact with oxygen. A dark red cone surrounds the wick. Of low temperature (1000° C), this cone is formed of vaporized carbon molecules. Around the dark cone is a brighter layer of incandescent carbon (1200° C), light yellow in color. A thin outer envelope of hot white light (1400° C) is faintly luminous and tends toward yellow at the tip (where the carbon is completely combusted). A spectroscope reveals bright gaseous bands surrounding the outer envelope, colored yellow, green, blue, red, and violet. Inspiration Linkwww.flickr.com/photos/philatkin/1454... ![]() ![]() |
