Abstract

A pyrotechnical object is made by compressing a pyrotechnical mass, and introducing into the mass an ignition and combustion accelerator in the form of a propellant powder. The propellant powder could be mixed with the mass prior to compression. Alternatively, the propellant powder could be pressed into an ignition surface of the mass after the pressing. The propellant powder may comprise basic cellulose and/or nitro-cellulose.
