Han-Blue

Long after the Ancient Egyptians had stopped painting the tombs and sarcophagi of the pharaohs, the Chinese were also in need of a blue. They independently formulated and their own synthetic pigment, very closely related to Egyptian blue.

Chinese skill was based upon the use of the natural minerals available to them, replacing calcium with barium.

Paint found on the famous Terracotta Army of Xi’an, has found Han Blue dated to 2500 years ago.

The fact the Egyptians and Chinese were each able to develop an identical synthetic blue pigment indicates the advanced na- ture of their craft skills even though they had no knowledge of chemistry in the modern sense.
