View of Mogao project team members injecting adhesive grout to reattach wall paintings. Special presses hold the plaster in place as the grout sets and dries. The grout, developed through extensive laboratory and in situ testing, is composed of local earth (the same type used to create the paintings) and lightweight components to prevent further weight-related stress on the paintings. The addition of small amounts of egg white increases the adhesion property of the grout, as well as its fluidity and lightweight properties. Photo: Francesca Piqué.
