La conservazione dei dipinti murali strappati applicati su masonite

The technique for detaching frescoes and transferring them to new support has been used until the XIX centuries, during the first sixty years of the 20th century, the detachment of wall paintings was a common practice to preserve frescos. Among the materials used for the new support, the most common was "Masonite®", made in wood fibers combined with various binders. The aim of this work was to study assess the conservation risks of detached wall paintings of the Green Cloister in Santa Maria Novella, in Florence, due to the deterioration of the support and its deformations. The research was carried out by a multi-disciplinary approach aimed at diagnosing the state of conservation of constituting materials.
