Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur , charcoal (which is mostly carbon ), and potassium nitrate (saltpeter) .
When the gunpowder was lit in the air-filled side, the rise in pressure would drive the water up the other side. [11] Like early steam engine designs, these engines used the air or vacuum created by gunpowder to directly lift the water. There were no mechanical parts in the manner of modern engines, which translate the power in the gas pressure ...
Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
The Tannenberg handgonne is a cast bronze firearm. Muzzle bore 15–16 mm. Found in the water well of the 1399 destroyed Tannenberg castle. Oldest surviving firearm from Germany. The earliest European references to gunpowder are found in Roger Bacon's Opus Majus from 1267. [39] [40]
Inference about the source of gunshot residue can be based on the examination of the particles found on a suspect and the population of particles found on the victim, in the firearm or in the cartridge case, as suggested by the ASTM Standard Guide for gunshot residue analysis by scanning electron microscopy/energy dispersive X-ray spectrometry.
The first useful explosive stronger than black powder was nitroglycerin, developed in 1847. Since nitroglycerin is a liquid and highly unstable, it was replaced by nitrocellulose , trinitrotoluene ( TNT ) in 1863, smokeless powder , dynamite in 1867 and gelignite (the latter two being sophisticated stabilized preparations of nitroglycerin ...
The highest concentrations of heavy metals were found in organic, plant-based, and these types of protein powders. Some protein powders contain cancer-causing toxins, new study shows, and these 3 ...
The Siege and Destruction of Jerusalem by the Romans Under the Command of Titus, A.D. 70, by David Roberts (1850), shows the city burning. Early thermal weapons, which used heat or burning action to destroy or damage enemy personnel, fortifications or territories, were employed in warfare during the classical and medieval periods (approximately the 8th century BC until the mid-16th century AD).
