iron-gallic

Ingredients

iron-gallic, vitriol, gum Arabic

Preparation Steps

Original Recipe Text

The index entries for 'ink (made of iron-gallic)', 'vitriol', and 'gum Arabic' all cross-reference pages 24 and 170 of the source text, strongly implying a documented recipe or description of iron-gall ink utilizing vitriol as the metal source and gum Arabic as the binder (p. 196, 197, 202).

Evidence

"ink (made of iron-gallic) 24, 170; vitriol 24, 170; gum Arabic 24, 170"

Remarks

The technical index of the volume explicitly links the chemical components of iron-gall ink—specifically iron-gallic compounds, vitriol, and gum Arabic—to detailed discussions on pages 24 and 170. This suggests these materials were a primary focus of the archaeometric or historical inquiry regarding writing fluids in the studied context (p. 196, 197, 202).
