Calcium-phytate treatment for iron gall ink

We are reviewing our treatment process of iron gall ink at the
British Library and are interested in others' experiences.

If you have carried out treatment of iron gall ink using the ICN
recommended calcium-phytate method, what are your practical
experiences and how did you reach the decision to use this treatment
procedure?

Do you feel the advantages of the treatment process outweigh any
potential risks?  What, in your opinion, are the greatest risks of
the treatment?
