Evidence
"The Raman bands centred at 258, 548 and 1098 cm−1 showed ultramarine blue as the pigment of the blue paint"
Remarks
Natural ultramarine, sourced as lapis lazuli from Afghanistan, is one of the most significant pigments in Persian painting. The presence of As, Zn, and Pb traces in the blue paint composition at Fahraj is of particular interest and may relate to the specific geological source or associated minerals (p. 222).
