Color of 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 … See more In the simplest case, the yellow flame is luminous due to small soot particles in the flame which are heated to incandescence. Producing a deliberately luminous flame requires either a shortage of combustion air (as in a See more Efficient combustion relies on the complete combustion of the fuel. Production of soot represents a waste of fuel (the soot could … See more When performing a flame test, the colour of a flame is affected by external materials added to it. A non-luminous flame is used, to avoid masking the test colour by the flame's colour. See more One of the most familiar instances of a luminous flame is produced by a Bunsen burner.
