Cannon bronze

Accdg to Dutton (Ref 58, p 32), Edward III of England was the first to add cannons to his Army. There were at least two clumsy bronze cannons with him when he crossed the channel to France in the War against Philippe de Valois... 

In order to create a big Navy, Henry VIII of England needed money which he got by confiscating the properties of Roman Catholic Churches and Monasteries. This money permitted him to create a Navy, which at the time of Henry s death (1547) amounted to 53 ships, all equipped with bronze cannons. With the... 

The anodes that have been used include stainless steels, mild steel, lead and platinised titanium, while typical electrolytes for ferrous materials have been 0.5 M sodium hydroxide, 0.2 M sodium carbonate, 0.5 M sodium sesquicar-bonate and tap water. For bronze cannons recovered from the Mary Rose, both sodium hydroxide and sodium carbonate electrolytes were employed while pewter artefacts (plates) from the same ship were treated in similar electrolytes or in a 0.5% solution of EDTA as a sodium salt in alkaline solution. 

The English are supposed to have used brass or bronze cannon for the first time during the reign of Edward iii (1327 to 1377), possibly at the siege of Cambrai in 1339 or a few years later at Crecy in 1346. These were perhaps imported from abroad, but cannon are believed to have been made in Britain not long after the experience that had been gained in the bell foundries (p. 107) no doubt proved invaluable. ... 

The only thing we did not have was a secret society guarding first-cenmry documents. But at least we had buried treasure—a railroad car full of bronze cannons and swords given to us by the French government after World War 1, supposedly buried when the site was closed. 

The consumption of cast iron rose considerably with the frequency of wars and the mechanization of the armies. It is said that during the Thirty Years War the Cathohc army under Tilly sent about 15 000 cannon balls of cast iron every day into Magdeburg at the siege of this town in 1631. Iron cannons were cast directly from the blast furnace. These pieces were inexpensive - compared to bronze cannons - but very heavy. They were not used for light field artillery but for permanent installations in forts and on ships.

Accdg to Colver (Ref 12, p 496), solid spherical projectiles for cannons started to replace the arrow-shaped projs. The material was stone, bronze or iron ... 

The early attempts to devise a bronze breech -loading cannon were unsuccessful because the backward pressure of the gas ultimately blew out the breech-block or else the gas created sufficient pressure against the walls of the barrel to burst it. As forged-alloy steels were perfected, breech-loading became a more practical possibility at the same time steel hoops or outer tubes were shrunk onto the barrel to strengthen it, or, at a later date, wire was wound around the barrel at high tension(Ref 2,p 83)... 

It had to be hollow, I decided, or it would weigh as much as a cannon and the floor beams would collapse. I took out my dagger and rapped the hilt on the god s chest. Yes, it was hollow. Bronze castings always are.
