History Edit. Though early thermal weapons, such as Greek fire, have existed since ancient times, the first widely used explosive in warfare and mining was black powder, invented in 9th century China (see the history of gunpowder).This material was sensitive to water, and evolved lots of dark smoke. The first useful explosive stronger than black powder was nitroglycerin, developed in 1847.
