Recipe Details
Ingredients
iron gallate, gum arabic, sulfate anion
Evidence
"Aceto’s results suggest a significant presence of iron gallate, gum arabic, and sulfate anion in the ink, made possible by XRF analysis (Aceto 288). Such results suggest that Codex A is the earliest known document written with iron gall ink."
Remarks
Codex A is reputed to be the oldest existent Latin translation of the New Testament’s four Gospels, dating between 345 and 371 A.D. (p. 77). It is significant as the earliest known document potentially written with iron gall ink (p. 78).
