3. Part of this research already has been undertaken; the results point to an inhibiting effect of the ammonium caseinate treatment on ink corrosion. Further research into the causes of this effect is planned.
4. A radical contains a free electron. This will try to form a bond with another electron, e.g. by separating a hydrogen atom from cellulose, a hydroxyl radical will form water and a cellulose radical.
5. Research, referred to under 2, has shown that EDTA (ethylene diamine tetra acetate), a chelating agent widely used in conservation, is not able to stop oxidative ink corrosion.

8. The aqueous solution of magnesium bicarbonate was prepared by saturating an aqueous supension of basic magnesium carbonate with carbon dioxide at I atm.
