In the 1500’s gunpowder was beggining to be used in Europe, and light firearms began to be used. Gradually, people began to get ideas that these small pistols could be enlarged to fire large stones and metal balls and so be more effective than the current catapults and trebuchets. Thus the cannon was born. Cannons were large hollow canisters with a hole approximately 7 in. across, and a much smaller one at the back about a centimeter in diameter. 

Gunpowder was poured through the front hole and a large metal or stone ball was rolled in after it. Then, a lighted match was touched to the gunpowder through the smaller hole and #BOOM# the ball is blown out the front with incredible force and blasted into the hull of an enemy ship.

These cannons were made of bronze, which is strong, and though it cannot hold an edge, does not need to. The reason Iron was not used is because before Henry Bessemer, Iron was too brittle and when the powder was lit, it would backfire, throwing shards of metal at the gunners. Not a pretty sight. As I said in my last blog, Steel could be produced, but in small quantities- a two ton cannon is not small quantity.
