| Abstract: | The approach to treating ink corrosion damage has undergone significant changes since the 1970s. This work traces the development of treatment methods using a 16th century drawing in iron gall ink as an example and draws up a conservation concept that takes into account the current state of research. The artwork underwent conservation treatment approximately 50 years ago as part of a diploma thesis at the Academy of Fine Arts Vienna. Through analysis of the original work, insight is provided into the past of ink corrosion conservation, detailing how the damage was addressed when the exact causes were not yet fully understood. Due to the continued deterioration, further conservation of the object was necessary, involving the removal of backings and materials added in the 1970s. In order to swell the water-based adhesive without causing migration of harmful iron ions from the ink due to moisture, a new method was first developed based on a test series and subsequently applied to the object. The method allows for localized treatment of ink corrosion and complexation of iron ions through the application of calcium phytate in the form of agar gel. Simultaneously, the moisture of the complexation solution swells the adhesive of the backings. A mineral clay poultice helps to largely prevent the formation of tide marks. Further testing is needed to make this promising method applicable for future use. |
