Аннотация:AbstractA purple barium copper silicate, BaCuSi206, an artificial inorganic pigment, has been identified, sometimes mixed with the known blue barium copper silicate, BaCuSi4O10. It occurs on- painted objects and in octagonal sticks from China attributed to the Han dynasty (208 Be-AD 220). This man-made pigment, for which the name Han purple is proposed, has not been previously characterized.
