In ceramics or ceramic tiles, sgraffito is a type of decoration received “by applying to an unfired ceramic body two successive layers of contrasting slip or glaze, and then in either case scratching so as to reveal parts of the underlying layer” (“Sgraffito” 2021). First, a drawing is cut out or scratched, usually in white engobe (slip) or the coloured one, contrasting to the colour of the body, or scratching in the body itself, which is successively covered with transparent, less often opaque glaze. This decoration was often found in Muslim ceramics. It has also been used in China. In Europe, it developed especially in Italy in the fifteenth century. But, “the Italian past participle ‘sgraffiato’, [which means scratched, scraped off or etched] is […] used especially of pottery” (Ibid.).
Sgraffito (graffito) is also one of the techniques of “wall decor produced by applying layers of plaster tinted in contrasting colours to a moistened surface” (“Sgraffito” 2021). It involves covering the wall with several, usually two layers of coloured plaster and partially scraping off the wet upper layers with sharp tools. In this way, the colour of the bottom layer is revealed in the scratched parts and a two or several-coloured composition is created, most often based on a geometric ornament. This technique was mainly used in a decoration of facades in architecture of Italian and Central European Renaissance. From the eighteenth century on, it was used quite sporadically.
