Recipe Details
Ingredients
verdigris, vinegar, copper, wine vinegar, gum arabic
Preparation Steps
Verdigris (zinjar) is prepared by reacting vinegar with copper (p. 21, note 150). For green ink, pulverized verdigris is stirred into a liquid base (p. 21). In another recipe, it is combined with wine vinegar, kneaded, and dried on a brick to remove moisture before being mixed with gallnut water (p. 25). It is also used in 'monk's ink' where it is added to a mixture of anemone leaf and myrtle water (p. 25).

Evidence
"Then pulverized verdigris is put in another pot and stirred. This is green ink."
Remarks
The text distinguishes between natural and compounded verdigris. Footnotes mention its medical utility for sores and burns in ancient times, but in the context of the manuscript, it is strictly an pigment for green and bluish-green inks (p. 21).
