This paper reports the results of a preliminary study of plastination as a consolidation technique for archaeological bone, waterlogged leather and waterlogged wood. Plastination is a technique that was originally designed for the preservation of anatomical specimens and that uses a silicon polymer as an impregnation agent. The standard plastination technique and several variations of it were evaluated and in the case of the waterlogged materials, compared with the effect of air drying and vacuum freeze drying. The treatments were ranked measuring the changes produced in weight, dimensions, colour, hardness (bone and wood), indentation resistance (wood only) and flexibility (leather only) of the specimens. The study included an assessment of the changes in some of the characteristics (colour, flexibility and indentation resistance) of plastinated specimens when exposed to high levels of light. A chemical analysis of the S10 polymer was also included. The silicon polymer studied was found to be a promising consolidant, to have good penetration, to cause little dimensional changes and to produce specimens aesthetically pleasing. Nevertheless, the plastination technique cannot be fully recommended until further studies demonstrate if the long term stability of the polymer and the qualities that it imparts to the objects justify the selection of an irremovable material for consolidation.
