The Native Village Buried By A Mudslide For 500 Years — And The 55,000 Artifacts Found Preserved Beneath The Mud
The primary conservation method used for the Ozette wooden objects was polyethylene glycol (PEG) treatment.
PEG is a water-soluble polymer that can slowly replace the water in waterlogged wood.
As the PEG solution permeates the wood over weeks or months, it fills the cellular spaces that the water had occupied.
When the wood is then slowly dried, the PEG remains in the cells, supporting the cellular structure in the way that the original wood substance once did.
The result is a stable, consolidated object that holds its shape and can be safely handled and stored.
