The Iron Age as mythology

Various civilisations have in their mythology of iron as it coming to our planet from the gods in heaven surrounding our planet.

Why would a brisk iron industry spring up around the world just when the highly developed, and in some ways ecumenical, old civilization, with its many thriving industries, collapses? The entrance upon the world stage of a new kind of work-material, intimately tied to the collapse, might help resolve this contradiction. Such was iron.

Of 86 known metals, ancient civilizations knew only seven, and their earliest use is conventionally set at:
1) Gold 6000 BC
2) Copper 4200 BC
3) Silver 4000 BC
4) Lead 3500 BC
5) Tin 1750 BC
6) Iron 1500 BC
7) Mercury 750 BC

Why was the Iron Age so late?

A dagger entombed alongside the mummy of Egyptian pharaoh Tutankhamun was made with iron that came from a meteorite, researchers say. The origin of its unrusted iron blade has baffled scientists because such metalwork was rare in ancient Egypt.

Why was it rare in some ancient countries who had immense empires? Or any country in Europe and Asia as they all seemed to be connected and trading with each other?

our finding provides important insight into the use of the term iron, quoted in relationship with the sky in Mesopotamian, Hittite, and Egyptian ancient texts: beside the hieroglyphic “image,” which already existed before the XIX dynasty with a broad meaning (as mineral, metal, iron), a new composite term “image,” literally translated as iron of the sky, came into use in the 19th dynasty (13th C BCE) to describe all types of iron.

In the same period, we can note a text at Karnak probably describing a meteorite. The introduction of the new composite term suggests that the ancient Egyptians, in the wake of other ancient people of the Mediterranean area, were aware that these rare chunks of iron fell from the sky already in the 13th C BCE, anticipating Western culture by more than two millennia.

Was the Iron Age due to the sudden appearance or deliverance of iron ore deposits and formation such as iron mountain ranges?

Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age. A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe3O4) or hematite (Fe2O3), alternating with bands of iron-poor shales and cherts, often red in color, of similar thickness, and containing microbands (sub-millimeter) of iron oxides.

Some of the oldest known rock formations (having formed ca 3,700 million years ago), are associated with banded iron formations. Banded iron formations account for more than 60% of global iron reserves, and can be found in Australia, Brazil, Canada, India, Russia, South Africa, Ukraine, and the United States.

In a typically condensed passage, Velikovsky summarizes the history of iron as it might have come to Egypt. The Iron Age in Egypt “may yet be proved to have even preceded the Bronze Age, is the opinion of one group of authors. The Iron Age began..with the end of the Middle Kingdom, is the opinion of another group, or in the time of Ramses II, according to a third group. The developed Iron Age in Egypt began in the days of Ramses III, a few scholars maintain. Many favor the date -1000 under the Libyan Dynasty

... The year -700 may be considered as the beginning of the Iron Age in Egypt is a statement often made. It is also asserted that the earliest smelting in Egypt (at Naucratis) dates from the Sixth Century. Iron has had more contradictory statements made about it than any other metal.” We are forced to notice that Ramses II and Nebuchadnezzar (Hattusilis) engaged in correspondence in which Ramses sought iron of better quality than was being made available to him from Egyptian mines and ovens that were being worked by Greeks. This would put the famous kings well into the Iron Age.

There would have been no Greek iron-workers anywhere, much less in Egypt, if conventional dating several centuries earlier were applied to these kings. In another place, Velikovsky surveys Egypt’s Bronze Age dynasties and concludes that “it was not because of lack of skill that iron was not utilized to a greater extent..” He calls our attention to the fine work that was done to cut and carve granite, basalt and diorite, which must have required the equivalent of excellent steel tools. But there is a mystery as to the provenance of these tools, and certainly little iron was used generally until the Iron Age.

Iron Age due to high iron ore temperatures?

Why was the Iron Age after the Bronze Age?

There is an easy technical answer to this, which is that the extraction of iron ore needed higher temperatures than the previous metals of the ages that proceeded it.

Iron Age mythology

The Bronze Age occurred before the Iron Age as the metals which make bronze are easily recovered from their ores, and the resulting alloy is soft enough to be easily worked with the raw materials which were then available. Bronze is an alloy of tin and copper and is lower in the reactivity series than iron. This means Bronze is easier to get out of its ore than iron. So bronze was found first as it was less reactive, and the tin and copper didn’t need deep mines to access the ore as it was found in the natural environment. Once the ore had been mined or found, the metal was easy to extract from the ore and with little equipment or need for extreme heat, the smelting process was easier that extracting iron.

Iron is a common element in the earth's crust, but it almost always occurs as a compound, it is very rare to find it naturally as metallic iron. It is much more difficult to smelt iron than bronze as in the copper smelting process the copper flows as a liquid to the bottom of the furnace. The slag of waste material accumulates on top of the copper, and can be poured off to leave behind the copper. The copper is easily identified as copper, and the process is intuitive. The copper and tin components to bronze did also not need major equipment or machinery to smelt the metal from the ore. The physical chemistry of smelting iron from oxide or sulfide ores differs from that of copper as you need incredible heat and technical machinery to make the iron metal. In principle, iron does not melt at the temperatures that can be reached in a primitive furnace: iron is still solid when copper and bronze are molten. This extreme heat caused the iron age to come after the bronze age, as to get the ore to the 1700 degrees Celsius, it needs to melt, technology had to improve to be able to heat the ore up to the needed temperature and the equipment needed to handle the molten iron were needed to be built as any object that could withstand the hot temperature needed to handle the molten iron were not even thought of.
