Paintings are often requested for loans to exhibitions in other museums. To ensure that they remain in a safe, stable environment from the time they leave the Walters to the time they return, especially vulnerable paintings are enclosed in a climate-controlled, in-frame vitrine, made for the individual piece. The vitrine ensures that the encapsulated painting will remain in the Walters’ relative humidity outside the museum walls. Our video demonstrates the vitrine-making process on one of the Walters’ most famous paintings.
