Synthesis and characterisation of lignin-like oligomers as a bio-inspired consolidant for waterlogged archaeological wood

What is it about?

The paper describes the preparation of a lignin based material for application as a consolidant for waterlogged archaeological wood. Included are details on how to prepare the material and the initial studies carried out on waterlogged archaeological wood showing that it is able to consolidate, by reducing shrinkage during drying.

Why is it important?

In the field of conservation of waterlogged archaeological wood the most prevalent method for consolidation is to use polyethylene glycol (PEG), which is currently prepared from fossil fuel sources. The material described within this paper offers a greener alternative to PEG and, with further development, will provide conservators with another material to choose from when deciding on a conservation stratergy.
