(ORDO NEWS) — Archaeologists have discovered a furnace in central China that was used during the Warring States period (475 BC – 221 BC) to smelt ductile iron. Xinhua news agency reported this on Saturday.
According to him, the researchers found the remains of a metalworking industry near the city of Xinzheng (Henan Province), where in ancient times there were state forges for the manufacture of weapons and tools used in everyday life.
Scientists have extracted products from underground, in the structure of which there is spherical granite – a component that gives gray cast iron the properties of steel.
“The discovery shows that China mastered the technology for the production of ductile iron at the beginning of the Warring States era,” said Fan Wenquan, an employee of the Institute of Cultural Heritage and Archeology of Henan Province. “This means that such a metal appeared in our country at least 200 years earlier than expected “.
In addition to the melting furnace, Chinese experts found more than 20 artifacts related to blacksmithing at the excavation site. It is assumed that these finds will significantly enrich the knowledge about the history of Ancient China.
