  • the proportion of the inert substances in the primers according to the invention can make up to 20% by weight.
  • the ignition kits according to the invention or the ignition mixtures are produced by methods known per se by mixing the individual constituents with the binder dissolved in a solvent or the secondary explosive which has binder properties. This mixing can be done by methods known per se by stirring, kneading or similar distribution methods.
  • the ignition charges according to the invention or the ignition mixtures are obtained as a pulpy mass.
  • the first charges according to the invention not only fulfill the function of a standard ignition charge, but can also be used directly without an additional booster charge.
