Iron gall ink corrosion on silk

I have recently received an album dated 1865. The album contains 65
drawings executed in ink on silk. Two types of inks have been
identified, one of them being iron gall. The drawings are showing
the typical signs of corrosion associated with iron gall ink,
similar to the ones normally observed on paper. I would be
interested in hearing from conservators/scientists investigating
iron gall ink corrosion specifically on silk and possible approaches
to treatment.
