The cup is a shallow oval, with handles (ears) on the long sides protected by gilt bronze mounts. It is painted with angular bird motifs resembling patterns on inlaid bronzes. To date, the earliest lacquer found in China was made around 7000 BC. Excavations have unearthed lacquer vessels with sophisticated inlays from the Shang period (about 1500-1050 BC) and high quality lacquers were produced in large quantities in the Warring States period (475-221 BC). By the Han dynasty, the lacquer industry was organised under government control and using early processes of mass production. This cup is evidence of this.The inscription neatly engraved around the side states that the cup was made for the emperor in AD 4 at the Western Factory workshop in Shu (now Sichuan Province). It goes on to name the craftsmen responsible for each step of the manufacturing process: making the wooden core, lacquering, top-coat lacquering, gilding the ear handles, painting, final polishing. It also names the inspectors, supervisors and deputies at the workshop. Lacquer requires many coats, with drying time between each, so specialization and assembly line production was very suitable.
