The present invention relates to methods of preparing pre-mixed compositions that can be combined to form pyrotechnic compositions. In exemplary embodiments, a binder ingredient is premixed with the pyrotechnic fuels and can also include other pyrotechnic additives and processing aides. Other binder ingredients can be premixed with the pyrotechnic oxidizers and can also include other pyrotechnic additives and processing aides. The resulting mixtures are not explosive and are therefore easier to store and much safer to handle. These pre-mixed mixtures can be stored in bulk until needed and rapidly combined to achieve final composition.
