Comparison of the History of Iron Smelting in Ancient China and the Western World

Iron is one of the most useful and important natural resources known to mankind. Not only because of its versatilities, but also because of its easy availability the Earth's surface. The Iron Age did not begin until about 1,200 BC. Different regions entered Iron Age in different times. Ancient Chinese had a late start entering this age comparing with Westerners. Regretfully, the usage of iron in ancient China is very often ignored by most scientific historians. Very few comprehensive studies of the history of iron usage and smelting in ancient China are available today. Quite possibly, the iron producing techniques in ancient China were more advanced than that of the Western World. Not long after the ancient Chinese began using it, iron products became more commonly available in China than in the West. In this paper, I will try to explain that the ancient Chinese had quite a few technical advantages in the processing of iron, and its usage in China was popularized faster than in any other parts of the world.
