Iron implements are made by smelting iron ore. The appearance of iron made epoch-making progress in human history. The Hittites, who lived in Asia Minor, were the first to make artificial iron in the world. The age was about 1400 BC. From 1300 to 1100 BC, iron smelting was introced into the two river valley and ancient Egypt, and parts of Europe also entered the iron age around 1000 BC. But at that time, the smelting was block ironmaking, and it was not until the invention of hydraulic blast furnace in Europe at the end of the Middle Ages (around 1400) that pig iron was smelted
