Recipe Details
Ingredients
copper, arsenic, acetate
Preparation Steps
Emerald green is a bright green synthetic pigment first synthesized in 1814 by Wilhelm Sattler (p. 12). Its identification in these manuscripts confirms a date after the mid-19th century, as it was likely introduced to Iran during that period and became common in the latter half of the 19th and first half of the 20th century (p. 12).

Evidence
"These bands are the identification characteristics of emerald green in Raman spectroscopy"
Remarks
The pigment was initially misdiagnosed as malachite based on multi-band imaging alone, highlighting the necessity of spectroscopic verification for green pigments (p. 12). The μ-XRF spectrum confirmed significant presence of both copper and arsenic (p. 13, Fig. 10a).
