The process of ironmaking has relied for centuries on iron ore, an impure form of iron oxide, slowly being reduced to iron by carbon monoxide in a furnace. Whether that furnace is the charcoal fire of ...

I tested a floating pulley blower during an iron smelt to simplify airflow and reduce mechanical failures. The blower ...

Massachusetts Institute of Technology engineers have demonstrated a more eco-friendly way to make iron. The method eliminates greenhouse gases typical of conventional iron production methods says team ...

Research from Cranfield University sheds new light onto the transition from the Bronze Age to the Iron Age, showing how experimentation with iron-rich rocks by copper smelters may have sparked the ...

Copper smelters from 3,000 years ago may have experimented with materials just enough to launch the Iron Age. The Bronze Age gave way to the Iron Age as the refining process of iron was discovered.

In the South Atlantic, stretching from Chile to South Africa, there’s a wide span where the Earth’s magnetic field isn’t quite in line with the rest. Here, at what’s called the South Atlantic Anomaly, ...

Buried deep in the south Georgia rolling hills, a tiny archaeological site has been rewriting history. Uncovered in the late 1950s, the Kvemo Bolnisi workshop was considered to be one of the ...

This finding suggests that the discovery of iron may have happened accidentally. Archaeologists may have uncovered crucial insights into the origins of the Iron Age through the study of a ...
