show dark halos around the silver ink lines as well as dark migration on at least one sample.
Among these the reference inks ST3 and ST4 show the most pronounced phenomena of
ink corrosion, particularly ST4. The ink corrosion and degradation phenomena of dark
halos and migration appeared always more pronounced on the thinner Late Antique style
parchment (LP).
In sub study 2 the reference samples of the reference ink ST14 showed the most serious
signs of damage (Fig. 33). ST14 as well as ST13 were prepared for further investigation
of the damage developed by ST3 and ST4. ST3 and ST4 were both prepared with wine
vinegar and contain either sodium hydrogen carbonate or potassium nitrate. ST13 was
produced solely using wine vinegar as a lubricant for the grinding process and contains no
further component. ST14 was not prepared using wine vinegar, but contains potassium
