verdigris

Ingredients

verdigris, old vinegar, saffron, gum arabic

Preparation Steps

Original Recipe Text

Verdigris is crushed in old vinegar and dried. Saffron is dissolved in gum arabic and vinegar, then mixed with the prepared verdigris to produce an emerald-colored ink (p. 224).

Evidence

"Take some verdigris, crush it well in old vinegar, and let it dry. Then pour ten dirhams of saffron dissolved in gum arabic with vinegar on it, mix it, make it into an ink, and then it will come out the colour of an emerald. (p. 224)"

Remarks

Raggetti notes that while verdigris-vinegar-gum mixtures are common, the addition of saffron is a specific variant found in other treatises like al-Marrākušī's (p. 224, n. 42).
