Archaeologists discovered smelting furnaces dating back to Liao Dynasty in Beijing
Smelting furnaces dating back to Liao Dynasty (907–1125) have been excavated in Beijing. The discovery has filled a blank in the research of smelting history in Liao Dynasty.
After years of survey and analysis, relevant archeological protection department has announced that the ruin of smelting furnaces, which was accidentally found by local villagers in 2005, is an intact smelting site tracing back to Liao Dynasty.
From four smelting furnaces in the 150 square-meter site, archaeologists have unearthed a variety of historical relics using for smelting, such as raw material, fuels, and fire-proofing materials.
"Some of the furnaces were built by stones, but there were some fire clay between the stones to protect the furnace," acknowledged Chen Jianli, associate professor at the School of Archaeology and Museology in elite Peking University.
"A furnace like this could produce more than one ton of smelted products in Liao Dynasty and that means 200-300 people were needed," Chen added.
The products from the ruins may be Iron weapons as the Beijing region then belongs to battlefield in Liao Dynasty. It also can serve as a piece of evidence to prove that the smelting skill spread from Central Plains to surrounding areas.
