- Résumé
- "The historic European art collection at the Agnes Etherington Art Centre is comprised of important 14th to 19th century pen and ink drawings. Given the time period of their creation, the media of a number of these drawings is likely to be iron gall ink which is known for its potential instability. This project surveys a selection of drawings from the collection to ascertain the presence of iron gall ink, characterize the ink recipe, assess the current condition of the drawings and provide long-term conservation recommendations. Studies have shown that copper ions contribute to a greater rate of oxidation than iron (II) ions. Despite this, most accepted conservation treatments for iron gall ink are targeted for use with ferrous ions. More data on the metallic components of iron gall ink in heritage objects is necessary in order for the conservation community to assess the need for developing alternate treatment methods. Analysis of the ink in the Agnes’ collection involved indicator papers to detect the presence and amount of iron(II) ions. Ultra-violet photography was used to help characterize the extent of degradation and X-ray fluorescence (XRF) was used to identify and establish relative amounts of component metals. Results of the survey indicated that a majority of the ink drawings contained iron gall ink. Iron was the most commonly found metal in the inks, but copper, lead, zinc, arsenic and manganese were also detected. When classified following the condition rating system outlined by the Netherlands Cultural Heritage Agency, the majority of the inks that tested positive for iron content were in good condition."
