From Wikipedia
Sgraffito is an artistic or decorative technique of scratching through a coating on a hard surface to reveal parts of an underlying layer contrasted in colour. It is produced on walls by applying layers of plaster tinted in contrasting colours to a moistened surface, and on pottery by applying two successive layers of contrasting slip or glaze to an unfired ceramic body. The Italian past participle sgraffiato is also used for this technique, especially in reference to pottery.
