Viet Nam Net, 28 June 2016
Axe- and chisel-shaped moulds made of stone dating back to the Dong Son civilisation (about 2,000 – 3,000 years ago) have been discovered in the northern mountainous province of Yen Bai.
The axe-shaped mould is 8.1cm long, 5.1cm wide and 2cm thick, and weighs 120 grammes. Meanwhile, the chisel-shaped one is 11.2cm long, 5.6cm wide and 3.2cm thick, and weighs 360 grammes.
The two stone moulds are being kept at the provincial museum, according to the museum’s Deputy Director Ly Kim Khoa.
He said in early March this year, a farmer found two stone objects with unusual carvings at an eroded section on the Hong (Red) riverbank in Dong An commune, Yen Bai’s Van Yen district. The farmer sent the objects to the museum for examination.
