2. Methanol has been used by the writer for water-damaged vellum at the Biblioteca Nazionale Centrale, Florence. The technique used was immersion of the vellum leaf in methanol followed by insertion in a thin polythene envelope (to inhibit evaporation of the methanol and contact with this toxic solvent) and then manipulation to ease out the distortion. Methanol is unpleasant to use, highly toxic and has no advantage over the ethanol/water solutions. The “damp-pack” interleaving humidification is the most frequently used method in TCD (at the moment) because it lends itself to a balance and efficient processing system of treatment for the normal run of distorted, but otherwise undamaged, vellum manuscripts. The moisture in the interleaving water leaf is controlled and checked with a moisture meter (Aqua-Boy). Contact between subject and the damp interleaving is prevented by an insulation of several layers of polyester web. The interleaving system requires careful preparation of the pack and very careful supervision; the process is rapid and requires precise timing.
