From the first transition series iron metal is the most common element forming Earth’s outer and inner core. In Earth’s outer core it is the fourth most common element. Iron is created from the extremely hot and large stars thought silicon burning process. In this burning process, Iron is the heaviest stable metal created from the calcium nucleus.
From all available elements in the universe, Iron is the sixth most abundant. It’s really tough to find Metallic iron on the surface of the earth because of its oxidizing nature. Most of the iron in the crust is found combined with oxygen as iron oxide minerals such as hematite and magnetite. Most of the irons are found in bound iron formations.
Iron objects last longer than objects made of silver and gold. From the ancient civilization, iron objects are of great use. Even in today, beads of meteoric iron from 3500 BC or earlier is found in Egypt, Gerzah. Meteoric iron was considered as originated from heavens and used to made weapons or tools by the ancient church. Before the advanced iron-working techniques cast-iron was used to created weapons.
Around 550 BC cast-iron was produced in China but was unavailable in Europe until medieval period. In the medieval period, Europeans produced wrought iron from cast-iron. In this procedure, charcoal was the fuel. Through the passage of time iron has become cheaper and plentiful. In the year 1778, the first iron bridge was built.
Another implementation of iron metal is steel. Steel was first ever produced in antiquity by using a bloomer. Around 1000 BC, blacksmiths in Luristan of western Iraq made good steel. India and Damascus developed the improved version of steel around 300 BC. Steel was developed in China in 500 BC. Steel producing methods were specialized and it has become a major commodity in the later 1850s.
