Flame temperature based on colour

  1. May 22, 2010 #1
    So I've been wondering, is it possible to determine how hot a flame is based on the colour? I know that you can classify it into general groups (yellow ~= 1000*C, etc.), but is there any way to get a more accurate temperature estimation? Any papers on this?

    You'd need a device to very accurately measure the wavelengths, but I cant think of anything stopping you.

    However I feel like there are more accurate and easy ways to measure temperature. Generally speaking I think it's more common to use color to analyze temperature distributions of a specific object.

    I think you need to be more quantitative - i.e. measuring the continuum wavelength distribution and fitting it. Otherwise you can be fooled by emission lines - put a tiny bit of a sodium salt in a blue flame and it turns yellow.
