Black Powder is a low explosive powder made from a combination of Sulphur (10%), charcoal (15%) and potassium nitrate (75%).
Black Powder deflagrates rather than explodes (i.e. has a velocity of Detonation <1000m/s) when confined and as such is suited for use in ‘gentle’ blasting applications such as dimension stone production, primarily to limit the formation of excessive cracks in the deposit being worked.
For specialist blasting applications EPC-UK stocks as standard Wano NPMG medium grained black powder (particle size approx. 0.8mm – 4mm), other grades are available on request.
