Iron meteorites consist overwhelmingly of nickel-iron alloys. The metal taken from these meteorites is known as meteoric iron and was one of the earliest sources of usable iron available to humans. Iron was extracted from iron–nickel alloys, which comprise about 6% of all meteorites that fall on the Earth.
There is evidence that iron was known from before 5000 BC. [15] The oldest known iron objects used by humans are some beads of meteoric iron , made in Egypt in about 4000 BC. The discovery of smelting around 3000 BC led to the start of the Iron Age around 1200 BC [ 16 ] and the prominent use of iron for tools and weapons. [ 17 ]
Iron production quickly followed during the 2nd century BC, and iron implements came to be used by farmers by the 1st century in southern Korea. [49] The earliest known cast-iron axes in southern Korea are found in the Geum River basin. The time that iron production begins is the same time that complex chiefdoms of Proto-historic Korea emerged.
The first iron production started in the Middle Bronze Age, but it took several centuries before iron displaced bronze. Samples of smelted iron from Asmar , Mesopotamia and Tall Chagar Bazaar in northern Syria were made sometime between 3000 and 2700 BC. [ 92 ]

Steel was known in antiquity and was produced in bloomeries and crucibles. [19] [20] The earliest known production of steel is seen in pieces of ironware excavated from an archaeological site in Anatolia (Kaman-Kalehöyük) which are nearly 4,000 years old, dating from 1800 BC. [21] [22]
The Iron Age began around 1200 BC and ended at around 500 BC. Humans may have smelted iron sporadically throughout the Bronze Age but was thought to be an inferior metal because iron tools and weapons weren't as hard or durable as bronze counterparts. [19] It was not until the creation of steel, combining iron and carbon, that iron became ...
In the 10th century BCE, glass production began in ancient Near East. In the 3rd century BCE, people in ancient India developed wootz steel, the first crucible steel. In the 1st century BCE, glassblowing techniques flourished in Phoenicia. In the 2nd century, CE steel-making became widespread in Han dynasty China.
