soot ink, iron gall ink

Ingredients

soot, iron gall

Evidence

"the same can be said of the use of soot ink, and even iron gall ink, or a mixture of both. Rubrication too is a common scribal technique, and is therefore not included, and although some coloured inks could perhaps offer slightly more information, technical analysis would be required, which was beyond the possibilities of the present study."

Remarks

The use of soot ink and iron gall ink is described as so universal in the Islamic world that the author determined they offer no clues to a manuscript's origin and thus were not systematically analyzed (p. 132).
