Dear Colleagues, I am confronted with a beautifully printed but very badly oxidized wall covering from around 1760-1765, still in situ. (See images). The dark printed areas are starting to break out; some have been glued back at a past time. I am looking into treatments in parallel to gall ink corrosion treatments. Has anybody ever treated printed cotton with cacium phytate? I have been reading about a research project into „dry iron gall ink stabilization“, but not found any results. Does anybody know more about it? The large size of the wall coverings (4 m x 2.2 m for the largest wall) and the fragility of the fabric would pose a serious risk when taking them down and bathing…. I am trying to compare pros and cons of all possibilities. Any ideas and thoughts are most welcome! Sincerely, Karin. Karin von Lerber Dipl.
