Iron must be Smelted in Oxygen free Furnace or Iron Oxide, Rust, is the Result.
It cost less to run thana colony did, and did not require a large comitment of military support
David Ricardo's "iron law of wages" basically states that parents would have more children if wages were raised. These children would then expand the number of workers and lower wages as they entered the labor market. Then, wages would fall and the workers would have fewer children. The process would then start over as wages would once again rise. He used this logic to advocate that wages would always tend toward a minimum level in the long run, hence the "iron law of wages" with static, unchanging wages. Many employers used this argument to support their natural reluctance to raise wages. This "iron law of wages" was also used to provide theoretical support for opposing labor unions.
The Hudson's Bay Company (HBC) had advantages over the North West Company (NWC) due to its established trading posts and strong ties with Indigenous communities, which facilitated access to fur resources. Additionally, HBC's royal charter provided it with a legal monopoly over vast territories, allowing for greater control over trade routes. Conversely, the NWC had superior logistics and a more agile operation, enabling it to respond quickly to changes in the fur market and to establish a more aggressive trading strategy. Its focus on a network of smaller, more flexible posts allowed for greater accessibility to fur-bearing regions.
Otto von Bismarck earned the title "Iron Chancellor" due to his pragmatic and often ruthless approach to politics, particularly in unifying Germany under Prussian leadership. He skillfully used diplomacy, war, and realpolitik to achieve his goals, emphasizing strength and order over idealism. His iron-fisted policies and ability to manipulate political situations solidified his reputation as a dominant figure in 19th-century European politics.
The word "evolution" refers to change over time, particularly in a gradual process. It is often used in biological contexts to describe how species adapt and develop over generations, but it can also apply to social, cultural, and technological changes.

The invention of the Bessemer Convertor in 1856 enabled the great increase in steel production of the late 1800s. Andrew Carnegie saw their potential on a trip to Sheffield, England built mills to use them in the United States. The Bessemer Convertor can take the output directly from a blast furnace and turn it into steel. As the iron goes from the blast furnace to the converter, other metals are thrown into the iron depending on the type of steel desired. Air is forced into the bottom of the convertor. It burns excess carbon out of the iron turning it into steel. Then the Bessemer Convertor is rolled over and the steel is poured into carts and taken to the next step. Previously Steel had been difficult to make and had been used for very few items. The Romans used it for swords but used iron for most utensils. Iron rails in rail road tracks could be replaced with steel rails and trains could double or triple in speed. After a number of years, Carnegie sold his company and it became U.S. Steel. He created a charitable foundation with the money he got from the sale of his company. That foundation created much of the public library system in the United States. It created an entertainment building in New York called Carnegie Hall. And it financed a study that led to a book by Gunnar Myrdal, called, An American Dilemma. That book provided the intellectual basis for the Civil rights movement.

Carbonium ion process
Carbonium ion process
The process of depositing a layer of zinc over iron is called galvanization. It helps protect the iron from corrosion by acting as a sacrificial anode, as zinc is more reactive than iron. This process is commonly used to create galvanized steel.
Iron was first discovered in ancient times by ancient Egyptians around 5000-3000 BC. The exact individual credited with the discovery of iron is unknown, but the use of iron became widespread during the Iron Age, roughly around 1200 BC.

Andrew Carnegie had a steel vertical monopoly by obtaining control over every level involved in steel production, from raw materials, transportation and manufacturing to distribution and finance.
Oxygen combines with iron in rocks through a process called oxidation. This reaction leads to the formation of iron oxide, commonly known as rust. Over time, this process can weaken the structure of the rock and change its color to a reddish-brown hue.
The process to make iron from iron ore is called iron smelting. Iron ore is heated in a blast furnace with coke (carbon) and limestone to remove impurities and extract the iron metal. The resulting product is molten iron, which is then cast into various shapes for use in manufacturing.
When carbon monoxide is passed over red hot iron at 120°C, a reaction occurs to form a compound called iron carbonyl. This process is known as the Mond process and is used for the purification of nickel. Iron carbonyl is a volatile compound that can be easily separated, leaving behind purified nickel.
