- Sparklers may utilize charcoal as the fuel that keeps the flame going because it burns slower than black powder.
- Sulfur, often used as an ignitor, gives the sparkler a bad smell when it burns.
- Aluminum gives the sparkler its silvery sparks. For gold colored sparks, iron is used.
- Potassium nitrate is used as an oxidizer in sparklers, which helps the charcoal burn.
- Sugar is sometimes used as a binding agent. Starch can also be utilized for the same purpose.
- All the ingredients of sparklers are mixed with water and dried on a metal wire.
