Ancient copper furnaces recently unearthed at an archaeological site in Dong Anh, in the north of Ha Noi, have shed important light on the Metal Age, according to archaeologists.
“This site was a bronze casting workshop, with dozens of furnaces, which we have found during seven excavations here since 1971,” said Lai Van Toi, from the Viet Nam Archaeology Institute.
Among artefacts found at the site are copper objects, cinders, broken pieces of pottery, pans and tripods â€“ which were probably part of a traditional kitchen.
Most of the furnaces, which are believed to be about 4,000 years old, were aligned along a northwest to southeast axis and evenly spaced. They were also of similar design.
