Barium sulphate is not present in traditional gunpowder.

Traditional black gunpowder consists of a mixture of three main components: Potassium nitrate (KNO₃), Charcoal (primarily carbon), and Sulphur (S).

Potassium nitrate acts as the oxidizer, providing oxygen for the rapid combustion of the fuel components, charcoal and sulphur. Sulphur also helps to stabilize the mixture and lowers the ignition temperature. Barium sulphate is sometimes used in pyrotechnics to produce a green color, but it is not a standard ingredient in black gunpowder propellant.
