During the Iron Age, the best tools and weapons were made from steel, particularly carbon alloys. Steel weapons and tools were nearly the same weight as those of bronze, but much stronger. Before the Industrial Revolution, which would take place centuries later, the majority of people lived an agrarian lifestyle.
Iron made life a lot easier in those days, when just living to the age of 45 was a feat. … Iron farming tools, such as sickles and plough tips, made the process more efficient and allowed farmers to exploit tougher soils, try new crops and have more time for other activities.
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. They found and extracted it from meteorites and used the ore to make spearheads, tools and other trinkets.

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.
Iron manufacture in the Middle Ages was comprised of essentially three practices: mining, smelting and smithing. … In effect, mining is the extraction of an ore or minerals, for example iron ore, from the earth, generally by means of tunneling or excavation.
The Latin name for iron is ferrum, which is the source of its atomic symbol, Fe. The word iron is from an Anglo-Saxon word, iren. The word iron is possibly derived from earlier words meaning “holy metal” because it was used to make the swords used in the Crusades, according to WebElements.

Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago (Mya). Evidence for the “microscopic traces of wood ash” as controlled use of fire by Homo erectus, beginning roughly 1 million years ago, has wide scholarly support.
As its name suggests, Iron Age technology is characterized by the production of tools and weaponry by ferrous metallurgy (ironworking), more specifically from carbon steel.
One of the remarkable achievements of the Neolithic Period was the invention of wheel. It brought a rapid progress in man’s life. The wheel was used in horse-carts and bullock-carts that helped man a lot to carry heavy loads. Therefore, in this period transport became quite easy and quick.
The Chinese produced cast iron as early as the 6th century bc, and it was produced sporadically in Europe by the 14th century. It was introduced into England about 1500; the first ironworks in America were established on the James River, Virginia, in 1619.
The Iron Age was a period in human history that started between 1200 B.C. and 600 B.C., depending on the region, and followed the Stone Age and Bronze Age. During the Iron Age, people across much of Europe, Asia and parts of Africa began making tools and weapons from iron and steel.
The Chalcolithic or Copper Age is the transitional period between the Neolithic and the Bronze Age. It is taken to begin around the mid-5th millennium BC, and ends with the beginning of the Bronze Age proper, in the late 4th to 3rd millennium BC, depending on the region.
The most recent Ice Age started between 110,000 and 70,000 years ago and lasted until around 12,000 years ago. people lived in hill forts built on higher land. The BRONZE AGE followed the Stone Age.
Today, iron is made by heating hematite or magnetite in a blast furnace along with with a form of carbon called “coke” as well as calcium carbonate (CaCO3), better known as limestone. This yields a compound that contains about 3 percent carbon and other adulterants – not ideal in quality, but good enough to make steel.
Our name for the element is derived from the Anglo-Saxon for silver, ‘seolfor,’ which itself comes from ancient Germanic ‘silabar. ‘ Silver’s chemical symbol, Ag, is an abbreviation of the Latin word for silver, ‘argentum.

Iron is a metal and the sixth most common chemical element in the universe. Iron makes up most of Earth’s inner and outer core, and it is also a major part of Earth’s crust. What is this? Iron is even found in the Sun, stars, and some planets too!
The only pure iron known to exist naturally comes from fallen meteorites. … Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.
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.
Early use. Scientists have never agreed on when humans began wearing clothes and estimates submitted by various experts have ranged greatly from 3 million to 40,000 years ago.
When Was the Stone Age? The Stone Age began about 2.6 million years ago, when researchers found the earliest evidence of humans using stone tools, and lasted until about 3,300 B.C. when the Bronze Age began.
Now, a new study argues that humans did not master fire until about 400,000 years ago.

The earliest evidence of extensive iron smelting comes from the Hittites, who ruled an empire in Anatolia from around 1500 BCE to 1177 BCE. Iron smelting technology gradually spread from Anatolia and Mesopotamia across Eurasia.
Humans made many technological advances during the Bronze Age, including the first writing systems and the invention of the wheel.
Paleolithic people were the first to create clothing, usually out of leather or linen, and even created needles with eyes for sewing. Most Paleolithic inventions and technologies were in the form of tools and weapons, like bows and arrows.
