THE GUNPOWDER INDUSTRY - Gunpowder is a mixture of saltpetre, charcoal and sulphur. Until the middle of the nineteenth century it was the only explosive available either for firing guns or for blasting in mines and quarries. This book outlines the process and history of its manufacture, from the development of gunpowder as a propellant in the fourteenth century, through its adoption as a blasting agent in the seventeenth, to the introduction of improved varieties shortly before its eclipse by high explosives.
