Original Recipe Text
Used as an imitation of gold. Its expanded use marks the transition from the Safavid era (where real gold was common) to the Qajar era (p. 14).
Evidence
"The presence of two elements of copper and zinc in golden II indicates the use of brass alloy, which was used as an imitation of gold in the decoration of some Qajar manuscripts."
Remarks
Corroded golden pigment was designated Golden II (p. 2). Presence of two golden types may indicate the work of two different authors (p. 14).
