Polyethylene glycol or PEG is commonly used for conservation of wood artifacts which have been preserved in a wet environment. PEG replaces the water content in the wood and by that way is deformation of the wood prevented when drying. The method may not be useful for dendrochronology according to reduced contrast and difficulty to determine the ring borders in PEG conserved wood.
