Bronze seal mould
Western Han dynasty, 3rd year of the Yuanshuo period(126 BC)
Height 2.7cm, Length 5.2cm, Width 5cm

This square mould has a flared mouth and smoothed edges. There is a protrusion in the base of the mould in the shape of a seal knob, next to which is a half-funnel-shaped protrusion connected to the mould. The exteriors of the left and right walls are chiselled with 15 characters in eight lines. These read “made by craftsman Shu Jin, i the 3rd year of the Yuanshao period, Shang Jun master craftsman Li Wu”. The exterior wall is uneven and the entire object is brown in colour. There is slight damage to the rim of the mouth. This object was a mould for casting bronze seals during the western Han dynasty. It illustrates the casting methods for bronze seals and is extremely precious due to its high historical value as material for research into ancient Chinese smelting technology.
