'Impasto' is a technique used in painting, where paint is laid on an area of the surface in very thick layers, usually thick enough that the brush or painting-knife strokes are visible. Paint can also be mixed right on the canvas. When dry, impasto provides texture; the paint appears to be coming out of the canvas.

The 'impasto' technique is usually associated with the work of Vincent Van Gogh. It is said that he applied the paints directly onto the canvas and simply mixed them together with his own fingers. One of the examples of the 'impasto' technique is the painting "The Starry Night".

Vincent Willem van Gogh (30 March 1853 – 29 July 1890) was a Dutch post-impressionist painter who posthumously became one of the most famous and influential figures in the history of Western art. In a decade, he created about 2,100 artworks, including around 860 oil paintings, most of which date from the last two years of his life.
