Let us give the Haya people some well deserved praise, shall we? This is the kind of metallurgy plot twist you don’t usually learn about in school

While basic iron smelting was widespread in the ancient world, the Haya in Tanzania took it further by creating forced-draft furnaces with an air preheating system around 2,000 years ago.

The furnaces were lined with refractory clay from termite mounds and used swamp grass to help control the carbon content, allowing them to make workable carbon steel.

The technique was studied extensively by Peter Schmidt and his team starting in the 1970s. Their work, including excavations and ethnographic research with Haya blacksmiths, was even published in Science magazine.

It’s not only a fascinating case of independent technological development in East Africa, but how different regions developed their own clever solutions for metalworking long before the Industrial Revolution.

That is absolutely amazing. Times like this I would love a Time Machine of sorts just to view history and see how they figured this all out.

Im lost why are we panicking? Why does knowing they made blast furnaces calm us down but knowing they used them makes us panic again?
