They were attempting to make the elixir of life, which was supposed to make you immortal, and was primarily for emperors,the T'ang dynasty(618-907.), fireworks were invented. These were originally for shows, but later on they used them to scare of enemies in war. The fireworks were mainly small bamboo cases filled with gunpowder, and a fuse was put on the side.
The Chinese were the first to discover iron casting around the sixth century, when they mixed tin and copper together. So they have the first iron cannon.
earlist pictures of european art(1327) are very similar to chinese 1128 sculptures, 1333 art is used in the UK to subdue berwick, but only against soft targets, it not being able to batter the walls down. This would be the case till 1430 in the hundred years war, when breaches in walls are mentioned, that make the towns undefensabble.
