Grattage
Surrealist painting technique
Grattage (literally "scratching", "scraping") is a technique in surrealist painting which consists of "scratching" fresh paint with a sharp blade.[1][2]
In this technique, one typically attempts to scratch and remove the chromatic pigment spread on a prepared support (the canvas or other material)[3] in order to move the surface and make it dynamic.[4] Incorporate the technique of grattage in the painting in order to create a strong sense of texture or pattern on the surface of the picture plane.[5]
This technique was used by Max Ernst,[6][7] Joan Miró,[8] and later by informal artists.
