The first bombards were made of iron, but bronze became more prevalent as it was recognized as more stable and capable of propelling stones weighing as much as 45 kilograms (99lb). Around the same period, the Byzantine Empire began to accumulate its own cannon to face the Ottoman Empire, starting with medium-sized cannon 3 feet (0.91m) long and of 10in calibre. [79] The earliest reliable recorded use of artillery in the region was against the Ottoman siege of Constantinople in 1396, forcing the Ottomans to withdraw. [79] The Ottomans acquired their own cannon and laid siege to the Byzantine capital again in 1422. By 1453, the Ottomans used 68 Hungarian-made cannon for the 55-day bombardment of the walls of Constantinople, "hurling the pieces everywhere and killing those who happened to be nearby". [79] The largest of their cannons was the Great Turkish Bombard, which required an operating crew of 200 men [80] and 70 oxen, and 10,000 men to transport it. [79] Gunpowder made the formerly devastating Greek fire obsolete, and with the final fall of Constantinople—which was protected by what were once the strongest walls in Europe—on 29 May 1453, "it was the end of an era in more ways than one".

I learned about artillery wheels so long ago that I have forgotten the source. But Google is full of information for any who want to search. Maybe the Australian field artillery service had a different design, but here is how the USA army field artillery in our Civil War did the wheels: Pour the dried cornstarch into a blender or food processor. Pulse for 30-60 seconds until the cornstarch has become a fine powder again. If the powder does not move or break up, it is probably still wet and needs to bake longer. If it does process but you need a finer powder, run it through a sifter as well. The earliest guns were probably cast from brass or bronze. Bell- founding techniques would have sufficed to produce the desired shapes, but alloys of copper, tin, and zinc were expensive and, at first, not well adapted to the containment of high-temperature, high-velocity gases. Wrought iron solved both of these problems. Construction involved forming a number of longitudinal staves into a tube by beating them around a form called a mandrel and welding them together. (Alternatively, a single sheet of iron could be wrapped around the mandrel and then welded closed; this was particularly suitable for smaller pieces.) The tube was then reinforced with a number of rings or sleeves (in effect, hoops). These were forged with an inside diameter about the same as the outside of the tube, raised to red or white heat, and slid into place over the cooled tube, where they were held firmly in place by thermal contraction. The sleeves or rings were butted against one another and the gaps between them sealed by a second layer of hoops. Forging a strong, gastight breech presented a particular problem that was usually solved by welding a tapered breech plug between the staves. Jarymowycz, Roman Johann (2001).

Stanley, Henry Edward John (1866). A Description of the Coasts of East Africa and Malabar in the Beginning of the Sixteenth Century by Duarte Barbosa. The Hakluyt Society.The breakthrough that led to the emergence of true cannon derived from three basic perceptions. The first was that gunpowder’s propellant force could be used most effectively by confining it within a tubular barrel. This stemmed from an awareness that gunpowder’s explosive energy did not act instantaneously upon the projectile but had to develop its force across time and space. The second perception was that methods of construction derived from cooperage could be used to construct tubular wrought-iron gun barrels. The third perception was that a spherical ball was the optimal projectile. The result was modern artillery. Wrought-iron muzzle-loaders

Never throw cornstarch (or any other powder) directly in someone’s face. Even if a product is completely natural and non-toxic (like cornstarch), that doesn’t mean inhaling it won’t cause problems. Cornstarch in particular has already been found to cause inflammation in the lungs. The mother-to-be in particular should stay out of the line of fire. Modern Asian Studies. Vol. 22, No. 3, Special Issue: Asian Studies in Honour of Professor Charles Boxer (1988), pp. 607–628. The first documented installation of a cannon on an aircraft was on the Voisin Canon in 1911, displayed at the Paris Exposition that year. By World War I, all of the major powers were experimenting with aircraft-mounted cannons; however their low rate of fire and great size and weight precluded any of them from being anything other than experimental. The most successful (or least unsuccessful) was the SPAD 12 Ca.1 with a single 37mm Puteaux mounted to fire between the cylinder banks and through the propeller boss of the aircraft's Hispano-Suiza 8C. The pilot (by necessity an ace) had to manually reload each round. [195]Ibn Khaldun reported the use of cannon as siege machines by the Marinid sultan Abu Yaqub Yusuf at the siege of Sijilmasa in 1274. [59] [65] The passage by Ibn Khaldun on the Marinid Siege of Sijilmassa in 1274 occurs as follows: "[The Sultan] installed siege engines ... and gunpowder engines ..., which project small balls of iron. These balls are ejected from a chamber ... placed in front of a kindling fire of gunpowder; this happens by a strange property which attributes all actions to the power of the Creator." [48] The source is not contemporary and was written a century later around 1382. Its interpretation has been rejected as anachronistic by some historians, who urge caution regarding claims of Islamic firearms use in the 1204–1324 period as late medieval Arabic texts used the same word for gunpowder, naft, as they did for an earlier incendiary, naphtha. [66] [64] Ágoston and Peter Purton note that in the 1204–1324 period, late medieval Arabic texts used the same word for gunpowder, naft, that they used for an earlier incendiary, naphtha. [67] Needham believes Ibn Khaldun was speaking of fire lances rather than hand cannon. [68]
