How the Mary Rose Has Survived
The Mary Rose sank in the Solent in 1545. When workers lifted the surviving hull on 11 October 1982, the ship had remained under the sea for 437 years.
Divers and archaeologists had searched, excavated, and recorded the wreck before the lift. They had attached the hull to a special frame and had placed it in a steel cradle.
Since 1982, conservators have been protecting the wet timber. The ship has undergone several stages of treatment because uncontrolled drying could make the wood shrink, bend, and crack.
From December 1982, staff sprayed the hull with fresh water. Before chemical treatment began in 1994, researchers had tested different methods. They chose polyethylene glycol, or PEG, a material that could fill spaces inside the damaged wood.
By 2013, the team had sprayed the ship with PEG for nineteen years. Then controlled air drying began.
