The Steel Saga
While modern steel production and usage in construction has only been around for the last two hundred plus years, steel manufacturing dates back thousands of years. During those years, people tried to improve on steel creation to make the carbon-rich steel stronger and more durable. People before the 17th century were at a disadvantage since they couldn't heat the metal to make the steel stronger. While steel was used in ancient China and in the Roman Empire, steel production in bulk for construction did not begin until the creation of blast furnaces, created specifically for melting ore and making steel with higher temperatures than ever before.
At the time a blast furnace was the best way to heat the ore and remove impurities and is still in use today. However, in the mid-19th century, a man called Henry Bessemer thought of a new way to produce steel. He created a device, called a Bessemer Converter, that would allow air flow to carry impurities out and away from the steel.

I grew up in the 1970′s and 80′s. The supersonic rate of technological advances was still in its infancy, and the simple pleasures in life were still fairly simple. One of the simple pleasures I had was going to visit my grandma. She lived about thirty minutes by bike from my house so I could just hop on my bike and see her anytime I [...]
