Frequently Asked Questions
Name, History & Etymology
History
Han Blue is an artificial pigment that was synthesized in China. Its chemical composition is barium copper silicate (BaCuSi4O10). It is closely related to Han Purple (barium copper silicate, BaCuSi2O6), with the main difference being the ratio of copper to silicon. Both pigments were developed during the Han Dynasty, though evidence suggests their use might predate this period. Han Blue was used extensively in murals, pottery, and other artifacts, particularly for decorative purposes. Its production involved heating a mixture of quartz, barium mineral (like witherite or barite), a copper compound, and a lead salt (as a flux) to temperatures between 900-1000 °C. The exact method of its discovery is unknown, but it is believed to have been a byproduct or intentional development from glassmaking or bronze metallurgy processes. Production of Han Blue largely ceased around the end of the Han Dynasty, possibly due to political instability, changes in artistic preferences, or the difficulty and cost of its manufacture.
First Recorded Use
c. 206 BCE - 9 CE
Cultural Associations
Han Blue, along with Han Purple, represents a significant technological achievement in ancient China, demonstrating advanced understanding of chemistry and materials science. Its vibrant blue color was highly valued and used to depict skies, water, and decorative patterns on various objects, including the famous Terracotta Army figures (though much of the original paint has faded). The pigments were also used in wall paintings and on ceramic glazes. The knowledge of its synthesis was lost for centuries until modern scientific analysis rediscovered its composition.
