How Iron was founded

Because iron is so hard to make, nobody used iron before about 1500 BC. Then the Hittites in West Asia did learn how to use it. They then quickly saw that iron weapons were better than bronze ones, and so they decided not to tell anybody else how to make iron. The Hittites kept the secret of making iron for about 400 years, until about 1100 BC, but when the Dark Ages came to West Asia, the Hittite empire fell apart anyway, and the secret of making iron got out to other people.

Making Steel

Iron bonds with other metals to make structures everywhere. This type of bond is metallic bonding. Steel is an iron-carbon alloy that does not undergo eutectic reaction, which means it is not a liquid and does not have to go through a cooling process.
