ABSTRACT: Using the theory developed in Part I, flame temperatures for various fireworks compositions have been measured by means of line-reversal of the Na-D lines. (1) For low flame temperature compositions: Compositions that contain combustible organic materials (i.e., shellac, rosin, pine root pitch, etc.) are commonly used in ordinary fireworks. The author prepared various combinations of components to see the influence of oxidizers, fuels, color agents, etc. Temperatures are measured by method 1 from Part I. The result shows that the highest temperature appears at the base of the flame. Generally potassium perchlorate gives higher temperatures than ammonium perchlorate. Potassium nitrate always gives lower temperatures than other oxidizers.
