Résumé

Since time immemorial drying has been used as a preservation process with some success. Freeze-drying, however, is the only process which enables one to dry a substance whilst preserving its physical, chemical, biological and organoleptic properties. Freeze-drying can be used to preserve cultural works in three specific areas: the preparation of plants or animals for museum exhibition; the salvaging of documents which have been accidentally water-logged; and the treatment of archaeological objects which have been recovered from damp or marshy terrain. The latter case is dealt with particularly. Rare archaeological or ethnological objects (some of the most ancient dating back to the mesolithic era) are often water-logged. if exposed to ambient air without proper pretreatment these objects are likely to undergo deteriorating reactions which have to be halted. When freeze-drying historical remains, one must preserve their form, size and particularly their internal structure since apart from their archaeological, ethnological and historical value, they are also of scientific interest as information can be obtained about the environment from where they were originally recovered.
