It identifies the presence of iron (II) ions (ferrous ions). These ions are responsible for iron gall ink corrosion , a destructive process that causes ink to eat through paper (oxidative degradation of cellulose). Gall-10rar
The (sometimes referred to as iron gall test paper) is a specially designed, non-bleeding test paper used in conservation to detect iron (II) ions in hydrophilic substrates. Key details about this paper include: Explain how to once it is detected Suggest
The test paper is moistened and applied to the ink. If iron (II) ions are present, the test paper changes color (turns a red/purple complex) due to the indicator bathophenanthroline reacting with the iron. The (sometimes referred to as iron gall test
