The grattage technique is created when a wet oil painting is pressed on top of various everyday materials, such as wood, mesh, string, glass, or wire, and the top layer of paint is scraped away with a palette knife or spatula, picking up spontaneous unexpected textures on the face of the painting.<\/p>\n<h2>What is the Effect of Grattage?<\/h2>\n<p>The grattage technique relies on unexpected marks and chance textures which the artist and audience respond to intuitively. Adding grattage to a painting may spark new ideas in the painter, or help to create something that their human hand could not replicate. It may help them to express a feeling or motif in their work that the impression of a physical object could best represent. Grattage may also create visual associations with natural elements, such as the surface of a tree, a towering mountain, or a crumbling wall. It may have a violent connotation, where the paint has been forcibly removed, perhaps leaving behind a shattered or rubble effect.<\/p>\n<p>Depending on the materials used to achieve the grattage, in combination with the colours used, and the content of the rest of the painting, its personality will shift. The work may gain an earthy grounded effect, or emulate human destruction. It\u2019s versatile as a technique since the results can be as varied as the materials and the arrangement that the artist experiments with.<\/p>\n<h2>The History of Grattage<\/h2>\n<p>The German Surrealist Max Ernst invented grattage in 1926, after seeking to transfer frottage \u2013 the other technique he coined \u2013 to painting. Earlier in his career, Ernst had been a prominent figure in the Dada collage movement, born out of the horrors of the First World War, and a rejection of the traditions of art and the establishment. Ernst served for four years in the war himself. His paintings following this period are full of personal mythology, reflections on childhood, his complex relationships, and a sense of destruction.<\/p>\n<p>After the outbreak of World War Two, he was identified as an enemy alien in France and was interned twice. After being freed in 1940 he fled to the Emergency Rescue Committee who helped artists to escape Nazi-occupied Europe. He travelled to America in 1941, where he would go on to make paintings that were influential to the Abstract Expressionists, leaving behind his frottage and grattage techniques, before returning again to France in 1953 where he remained until his death. His oeuvre is marked by shifts in personal history, location, tragedy and romance, and developing his techniques as he went. Grattage was invented amidst a short window between World Wars, and the visual connection between debris and a shattered picture plane is inevitably linked.<\/p>\n<p>The unusual and unexpected patterns of marks that the technique created became a point of departure for his paintings, where he would react to the characters or scenes they conjured up in his imagination, and put them to paint. He would often cover much of the grattage effect with other paint, only allowing specific areas to show through.<\/p>\n<p><em>The Horde<\/em> is part of a series of paintings of the same title that Ernst created using grattage to generate the nightmarish humanoid animal creatures that crowd the paintings. Max Ernst <em>Showing a Young Girl the Head of his Father<\/em> uses grattage to create the texture of the looming forest in the unsettling scene, and in <em>The Great Lover I<\/em>, grattage is used in the texture of the steep walls on the left around the fragmented torso. <em>Forest and Dove<\/em> depicts another forest crowded by grattage-filled trees, this time crowding the enveloped symbol of peace.<\/p>\n<p>Grattage aligns with the ideals of Surrealism, from transforming everyday objects into the uncanny to turning inward to the subconscious to generate ideas. The group was very interested in Freud\u2019s writings, which steered them toward pursuing Automatism \u2013 an art generated without conscious thinking, like people breathe or sleep. Grattage can be seen as an extension of these ideas, as Ernst said himself, \u201cI came to assist as a spectator at the birth of all my works\u201d.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-1566211\" src=\"https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15.jpg\" alt=\"\" width=\"1200\" height=\"800\" srcset=\"https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15.jpg 1200w, https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15-300x200.jpg 300w, https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15-1024x683.jpg 1024w, https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15-768x512.jpg 768w, https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15-620x413.jpg 620w, https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15-192x128.jpg 192w, https:\/\/www.jacksonsart.com\/blog\/wp-content\/uploads\/2025\/07\/Grattage_Technique_Blog_Image-15-940x627.jpg 940w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<h2>Demonstrations of the Grattage Technique in Painting<\/h2>\n<p>For my first example, I wanted to try creating grattage with a variety of studio objects.
