How did ancient civilizations make ovens so hot that they could melt metal without the kinds on materials we have today?
In: Engineering
You can make a something capable of melting iron out of clay you dig up locally and basic fuel, like coal. It’s not difficult. You just need proper airflow.
Also, to work metal you don’t need to melt it. Just heat it until you can work it with a hammer and tools.
That’s why it’s such old knowledge. It’s what let us get to the point we can melt materials with a much higher melting point,like tungsten.
