Flash Powder (Nitrate)
From PyroGuide
Nitrate flash is a type of flash powder that uses a nitrate as its oxidizer. This is a very common type of flash powder, has good strength, and relatively-low sensitivity to friction and shock. Nitrate flash is usually safer to handle than some other flash powders--like those that utilize chlorates or permanganates. However, all compositions containing nitrates and Aluminium create basic conditions, evolving heat that can lead to spontaneous combustion. A small percent of boric acid should be added to counter this reaction. A great variety of nitrate flash mixtures exist. Never mill or hand grind flash powders!
Compositions
Magnalium based flash
| Potassium nitrate | 55 |
| Magnalium | 45 |
| Sulfur | 5 |
Caution: This is a very powerful mix with it using magnalium. It must be made and handled with extreme caution!
| Potassium nitrate | 50 |
| Aluminum powder | 30 |
| Sulfur | 20 |
| Potassium nitrate | 60 |
| Aluminum powder | 30 |
| Sulfur | 10 |
| Potassium nitrate | 67 |
| Aluminum powder | 16.5 |
| Sulfur | 16.5 |
Magnesium Composition
| Potassium nitrate | 50 |
| Magnesium Powder | 50 |
Caution: Magnesium flash is more unstable, it decomposes over time and sometimes can spontaneously combust. Coat your magnesium with linseed oil to prevent unwanted reactions
Method
Mix together using the diaper method. Do not use any other method when creating flash powder as it is very sensitive. Do not ram or wet.
