Description
Black Powder is a mechanical mixture of potassium nitrate, sulfur and charcoal. The standard composition is 75% potassium nitrate, 10% sulpher and 15% charcoal. The ingredients in given proportions are intimately mixed, compacted and then broken in a coming mill. The Black Powder is then grain classified and the resulting grades are glazed with or without graphite depending on the intended use. The chemical composition, the compression, the granulation and the polish are decisive factors for the characteristics of every type of Black Powder.
This particular one is of granulation 1.18 to 1.7 mm in size.
