In addition to its use as a fuel,  it can also be used as a colorant in crackling stars to produce colored sparks along with the crackling sound.

Harmful by inhalation, in contact with skin and if swallowed. Wear suitable protective clothing when working with it, such as dust mask and latex gloves.
