PURPOSE: Provided are a composition and a method of preparing a non-toxic primer mix including both bismuth sulfide and potassium nitrate as the pyrotechnic portion of the primer mix. CONSTITUTION: The non-toxic primer mix contains approximately 2-20% by weight bismuth sulfide, approximately 25-70% by weight potassium nitrate and approximately 25-50% by weight of a lead-free explosive material. Additionally, the primer can include additional fuels such as nitrocellulose, aluminum, manganese and manganese oxide. Furthermore, pentaerythritol tetranitrate (PETN) may be included as a primary explosive, and gum arabic used as a binder.
