FINTI MARMI E LEGNI
Sgraffito is an ancient wall painting decoration, similar to the painting of frescoes, produced by applying two or more layers of plaster tinted in contrasting colors to a moistened surface. This art technique developed between the sixteenth and seventeenth century as façade chiaroscuro decoration of palaces and courtyards. During that time, its materials appeared less incline to weather away than wall paintings. The sgraffito technique has enabled the realization of masterpieces, from simple to complex decorations, from geometrical to damasked patterns, from zoomorphic to floral patterns. This art technique, like the frescoes, is executed upon freshly-laid plaster composed by a mixture, in various percentages, of hydrated lime (slaked lime), siliceous sand, marble powder and colorful sands (pigments).
