Charcoal finds widespread use in pyrotechnics. Many types of charcoal exist, each with its own properties. It is a complex organic substance containing moisture, ash, carbon, hydrogen, oxygen and a variety of volatiles. All of these elements have a vital use in fireworks. Charcoal made from eastern red cedar and paulownia are considered great for black powder, while hardwood charcoals e.g. southern yellow pine charcoal are commonly used for spark effects. The particle size and the process used to make the charcoal also play an important role in the quality of the charcoal for a specific purpose. Very fine charcoal floats in the air and is therefore sometimes referred to as ‘airfloat’.
