Abstract: The spectra of the colored flames of firework compositions were measured with a spectrometer and processed into chromaticity coordinates. The change in color purity as a function of composition is shown using chromaticity diagrams. Firework star compositions of red, yellow, green and blue were tested. The components of the compositions were altered to investigate the influence of color agents, chlorine donors and high energy agents on the colored flames.
Keywords: firework composition, combustion, colored flame, chromaticity diagram
