	Gunpowder - Wikipedia, the free encyclopedia
		Gunpowder, whether fl powder or smokeless powder, is a substance that burns very rapidly, releasing gases that act as a propellant in firearms.
		Gunpowder spread to the Arabs in the 13th century.
		In Europe, the first written reference to gunpowder was set down by Roger Bacon in the works he prepared for Pope Clement IV around 1267: "a child’s toy of sound and fire made in various parts of the world with powder of saltpeter, sulphur and charcoal of hazelwood.

	Gunpowder warfare - Wikipedia, the free encyclopedia
		Gunpowder warfare is associated with the start of the widespread use of gunpowder and the development of suitable weapons to use the explosive.
		The understanding of "gunpowder warfare", expressed here, comes from the works of Michael Roberts who argued that a military revolution occurred in the sixteenth century that forever changed warfare, and society in general.
		Gunpowder, explosive weapons had been used in China centuries before cannon appeared in Europe.

	Gunpowder - LoveToKnow 1911
		The manufacture of gunpowder seems to have been carried on as a crown monopoly about the time of Elizabeth, and regulations respecting gunpowder and nitre were made about 1623 (James I.).
		A good deal of the fieriness and violence of explosion of a gunpowder depends on the mode of burning of the charcoal as well as on the wood from which it is made.
		In the chemical examination of gunpowder the points to be ascertained are, in addition to moisture, freedom from chlorides or sulphates, and correct proportion of nitre and sulphur to charcoal.

	Gunpowder Plot - LoveToKnow 1911
		The steps taken by Salisbury after the discovery of the gunpowder do not show the possession of any information of the plot or of the persons who were its chief agents outside Fawkes's first statement, and his knowledge is seen to develop according to the successive disclosures and confessions of the latter.
		Thus on the 7th of November he had no knowledge of the mine, and it is only after Fawkes's examination by torture on the 9th, when the names of the conspirators were drawn from him, that the government was able to classify them according to their guilt and extent of their participation.
		They now began to feel themselves abandoned not only by man but by God; for an explosion of some of their gunpowder, on the morning of the 8th, by which Catesby and some others were scorched, struck terror into their hearts as a judgment from heaven.

	gunpowder. The Columbia Encyclopedia, Sixth Edition. 2001-05
		In the past gunpowder was widely used for blasting and for propelling bullets from guns but it has been largely replaced by more powerful explosives.
		The origin of gunpowder was probably Chinese, for it seems to have been known in China at least as early as the 9th cent.
		Gunpowder was the only explosive in wide use until the middle of the 19th cent., when it was superseded by nitroglycerine-based explosives.

	Gunpowder Weapons of the Late Fifteenth Century
		Gunpowder weapons were the 'leading edge' of technology in the late medieval era.
		All forms of gunpowder weapons relied on chemical and metal-working advancements of the time, and their effective exploitation in warfare relied upon new thinking of the military commanders.
		The introduction of gunpowder weapons was an evolutionary process that required progress in technology and in understanding of commanders (the best of whom were not the traditional knight, or noble men-at-arms, who were the main subjects of the contemporary chronicles).

	gunpowder
		Claims that gunpowder was invented in China rest on variable interpretations of certain passages in ancient manuscripts.
		Now, in gunpowder, the rapid burning of the charcoal in free oxygen releases additional oxygen from the saltpeter which rapidly oxidizes the sulphur, thereby creating the voluminous expansion of gases which provides the propellent power for which the substance is known.
		This is unquestionably gunpowder, for it will go off with a "bang", though not quite the "bang" one would get from the optimal formula, which is 74.64% pure saltpeter, 11.85% pure sulphur, and 13.51% charcoal.

		A novelist and popular history writer, Kelly traces the history of gunpowder from 10th-century China to the late 19th century, when it was supplanted by Alfred Nobel’s nitroglycerin.
		Kelly takes advantage of gunpowder’s role in the histories of armaments and war to titillate with gruesome but fascinating accounts of the atrocities the destructive power of gunpowder visited on Europe: in the 30 Years War, the German states lost an estimated eight million people—one-third of their population.
		With similarly lively portraits of figures who chaperoned gunpowder to its technical peak in the 1800s, the Du Ponts on the manufacturing side, or the inventors of revolvers and rifled arms on the weaponry side, Kelly accesses history through technology.
