This article considers a technique developed by the authors for preserving archaeological objects made from organic materials. This technique protects artifacts without applying additional reactants for mechanical durability. Its application can prevent the growth of microflora in storage conditions where humidity and temperature fluctuate beyond desirable ranges. This way of processing archaeological organic material is ideal from an ecological point of view. The time-reversible method outlined here enables the effective removal of microflora, avoids the use of chemical compounds incompatible with subsequent artifact processing or with the preservation of objects’ appearance and structure, and also does not demand considerable material expenditures of labor or specially equipped laboratories.
