Study on the Pigments in the Cruciform Gallery of Angkor Wat, Cambodia

A study on the pigments used in Angkor Wat's cruciform gallery reveals that red and orange pigments, specifically hematite (laterite) and minium, were applied in distinct sequences across different areas. Minium, identified as the underlying orange pigment, suggests it was used during the Angkor Wat style period, while hematite, the overlying red pigment, likely dates to the Bayon style period or later, primarily before the early 17th century. The research also confirmed a diverse range of substances, including calcium oxalate hydrates, Pb–Cl compounds, and other minerals, providing insights into the materials and techniques used in Angkor Wat's decorative artistry.
