Innovative Furnaces for Metal Production in Central Asia
Central Asian communities in the Bronze Age used innovative deep-shaft furnaces for smelting sulphur-rich copper ores. The furnaces had long channels for firing, creating differential pressure to eliminate sulphur fumes. With these furnaces, they could produce 600 to 800 kilograms of metal in one go for at least 400 years.
