Composition
Description
A weak fire dust is obtained since the composition contains no sulfur. It creates a different and lonely effect.
The composition is very high in charcoal, and thus tends to be slow burning, and is at risk to becoming Driven in.
Method: To obtain the fire dust, the potassium nitrate must be soaked into the charcoal. Hence a wet proces must be used for mixing.
