History and properties of iron Archeologists estimate that people have been using iron for more than 5,000 years, according to Jefferson Lab. In fact, it turns out that some of the most ancient iron known to humans literally fell from the sky.

When was iron first discovered?
Archeologists believe that iron was discovered by the Hittites of ancient Egypt somewhere between 5000 and 3000 BCE. During this time, they hammered or pounded the metal to create tools and weapons.
How long has iron been on Earth?
Iron has been known to humankind since about 3500 B.C., or over 5,500 years ago. Its name is derived from the Anglo-Saxon version, which was "iren." The periodic table iron symbol Fe comes from the Latin word for iron, which is ferrum.
What is the history of iron?
Iron has been known since ancient times. The first iron used by humans is likely to have come from meteorites. ... In Mesopotamia (Iraq) there is evidence people were smelting iron around 5000 BC. Artifacts made of smelted iron have been found dating from about 3000 BC in Egypt and Mesopotamia.
What age came after the Iron Age?
The end of the Iron Age is generally considered to coincide with the Roman Conquests, and history books tell us that it was succeeded by Antiquity and then the Middle Ages.
Are we still in the Iron Age?
Our current archaeological three-age system – Stone Age, Bronze Age, Iron Age – ends in the same place, and suggests that we haven't yet left the iron age.
Is iron not from Earth?
Iron is made inside stars, more specifically red giants. The red giant during its formation transforms all of its helium into carbon and oxygen atoms. ... The core of the Earth is made almost entirely of metal—specifically, iron and nickel.
Is iron native to Earth?
Most of the native iron on earth is actually not in fact "native", in the traditional sense, to Earth. It mainly comes from iron-nickel meteorites that formed millions of years ago but were preserved from chemical attack by the vacuum of space, and fell to the earth a relatively short time ago.
Who Discovered iron?
The first person to explain the various types of iron was René Antoine Ferchault de Réaumur who wrote a book on the subject in 1722. This explained how steel, wrought iron, and cast iron, were to be distinguished by the amount of charcoal (carbon) they contained.
What was invented in the Iron Age?
The Iron Age saw the introduction of two very important artisans tools: the potter's wheel and the wood pole lathe. Before the potter's wheel, people made pottery by rolling and coiling clay; the wheel made the process faster and more efficient.
Why was it called the Iron Age?
The Iron Age was a prehistoric, archaeological era that existed from around 1200 BC to 100 BC (the 12th to 1st Centuries Before Christ). During the Iron Age, iron material was commonly used to make tools, so the era was named after it.
How was iron created?
By scientific standards, the origin of iron is one of the most violent processes imaginable. A type of star known as a red giant begins to turn all of its helium into carbon and oxygen atoms. Those atoms then begin to turn into iron atoms, the heaviest type of atom a star can produce.
What Colour is iron?
Pristine and smooth pure iron surfaces are mirror-like silvery-gray. However, iron reacts readily with oxygen and water to give brown to black hydrated iron oxides, commonly known as rust.
What makes iron so special?
Iron is a "special" element because of its nuclear binding energy. The very basic idea is that when you fuse two light elements together, you get a heavier element plus energy. You can do this up to iron.
How much iron is in the human body?
Males of average height have about 4 grams of iron in their body, females about 3.5 grams; children will usually have 3 grams or less. These 3-4 grams are distributed throughout the body in hemoglobin, tissues, muscles, bone marrow, blood proteins, enzymes, ferritin, hemosiderin, and transport in plasma.
