The Darker the Coal is
Darker the fire would,
As it catches fire due to Oxygen
Blow bright and harmful.
Color Black in touch,
Rough too cause it's dark.
Neither tasty nor bitter,
The result is always fire.
Release anger as Carbonate,
While it's a chemical subject.
Being Coal, being dark,
Most of us blow that flame,
As same as Coal do.
