or sgraffito. Mural painting, that, for the most part, consists of decorative features executed with an iron point, called a sgraffito, on an intonaco prepared appropriately for this technique. Graffito was widely used in the 16th Century, in particular for the decoration of palace facades. Filippo Baldinucci (1681) describes the procedure as follows: “All of the area is outlined with an iron point, incising the intonaco first with a black colour tint and then covered with white made of travertine lime mortar of. Removing the white and uncovering the black, a picture or a design remains….with its lights and darks, that helped by some dark watercolours, forms a pretty relief and makes a beautiful vision.”
