The treatment of works on paper with iron gall ink is undertaken after a thorough examination of<br />
the artifact and an evaluation of the benefits of any treatment compared to the risks. Diagnostic tools<br />
and factors used to determine the condition of the artifact and need <strong>for</strong> treatment include the ICN<br />
condition rating, fluorescence of ink under UV illumination, bathaphenanthroline Fe(II) and pH tests,<br />
inkline thickness and colour, and paper thickness, sizing and absorbency. Following evaluation and<br />
consideration of this in<strong>for</strong>mation the conservator may or may not decide to treat the work. The aim<br />
of this poster is to aid the conservator through this decision-making process, present a summary of<br />
treatments currently available, highlight key treatment steps, and offer some practical tips.
