Plans for converting from batch processing to automated, primarily continuous production of black powder, involving among numerous changes, replacement of the traditional wheel mill by a jet mill, have raised concerns over the possibility of consequent modifications in performance of black-powder primers for propelling charges. As a step in preparing to test the performance of the material produced by the new process, the Product Assurance Directorate asked the author to investigate the role of black powder in ignition trains, to review literature on its ignition and burning mechanisms, to propose a mechanism for its participation in the ignition sequence, and to suggest a performance- oriented laboratory test that eventually might be employed as a basis for product acceptance. The report details the results of this investigation.
