Restoration and conservation of wooden archaeological finds by means of the DIC (Detente Instantanee Controlee)


Object of the research program is the study of a new system for the restoration and the conservation of wooden archaeological finds deteriorated after centuries of immersion in sea lake water. In these artefacts the cellulose that makes up the fibres is almost completely gone (solubised) and the same fibres are mostly made up of lignin and minerals; in the objects found in sea water, moreover, there is a penetration of aniomic compounds (clorides and alkaline sulphates) in the very porous wood structure; fungi, bacteria and small molluscs can also be present and keep damaging the structure even after a normal drying treatment. The DIC process includes a quick heating process (some dozens of seconds) in the presence of sturated vapour pressure, followed by a very rapid phase of decompression and cooling that causes the treated material to dry up almost completely without causing its structure to contract and without alterations in its chromatic and aesthetic characteristics. The treated material, therefore, although it is sterilised, has an "open"structure ready to receive deep consolidating treatment using products that have a low impact on the environmental that could not otherwise be utilised.
