Gunpowder is KNO3, sulfur, and charcoal - see http://en.wikipedia.org/wiki/Gunpowder Original black powder was just KNO3 and fine charcoal - blunderbuss stuff. It is only explosive when finely ground and mixed very thorughly. When coarsely mixed, as in soaking KNO3 into a stump, it will smolder/burn/smolder/burn, like a very slow sputtering fuse.
