The PEG treatment is often paired with vacuum freeze-drying, as the eutectic point of most PEG solutions is below the freezing point of water. This allows the "free" waterlogging water to sublimate in the process of freeze-drying, which minimizes damage to the wood by preventing ice from forming within the cells and expanding, causing more ...
