Fresco
Literally, the mural on a layer of wet plaster. In the fresco itself, the buon fresco, the coating with successive layers of plaster is preceded, and while the last layer (intonaco) is still fresh, the painter, applies the colors in order to be "integrated" into the wall. This technique, perfected in the Renaissance period, produces, to the extent that the climatic conditions are right, very durable projects. Perhaps the best known examples of such frescoes are the ceiling of Michelangelo in the Sistine Chapel and Raphael's decorations in the halls of the Vatican Palace. The so-called fresco secco (= dry fresco) made over a dry, ready for use plaster (as a result a range of colors is more limited and there is the possibility of peeling), characterized by subtle tones and brighter colors and, for this perhaps is why was really popular during the Baroque period.
