Original Recipe Text

Evidence
"Material analyses of the colour have identified orpiment and indigo as the main components of the more visible stain left on fol. 17r and a recipe of a green liqa mentioning the ingredients detected has been found on its verso"
Remarks
The fingerprints suggest the user was searching for a corresponding passage while working. The scribe, possibly Sadr al-Din Musa al-Katib, produced this manuscript in the early 19th century (1228 AH). The stain is located on fol. 17r (p. 108).
