Abstract
A method for preparing a pyrotechnic composition which comprises preparing a composition in a gel form using nitrocellulose and a nitro compound other than nitrocellulose, adding an oxidizing agent, a combustible material and a color rendering agent to the composition, followed by mixing, forming the resultant mixture into a desired shape, and then drying; and a pyrotechnic composition obtainable by using the method. This method can be used for simplifying a production process while maintaining the effect of a star and a lance used in a pyrotechnic composition, particularly in a firework composition.
Claims5
A pyrotechnic composition prepared by mixing nitrocellulose and a nitroalkane to prepare a composition in a gel form, mixing an oxidizing agent, a fuel and a color producing agent to the composition and then drying to remove the nitroalkane from the gel.
