Recipe Details
Preparation Steps
The analysis suggests the scribe did not prepare the inks but bought them. The ink sequence shows a start with iron-gall ink, a switch to carbon ink, and a final return to iron-gall ink, indicating the scribe used whatever ink was available without significant preference (p. 127).

Evidence
"The first line and a half and the marginalia are both written with iron-gall ink, while the rest of the text is written with carbon ink; this can be seen in Figure 4.31 b-d, through the change or maintenance of opacity under NIR light."
Remarks
The document (H 00161) is a legal deposition concerning a shipwreck. Only reflectography was performed, so it remains unconfirmed if the carbon-based ink is pure carbon or a mixed ink. The ink varies on the verso between iron-gall and carbon types several times (p. 126).
