Impasto
Impasto is a term used in painting and sometimes in pottery.
It means the paint is laid on thickly in places, thick enough so the brush or painting-knife strokes can be seen. When dry, impasto gives texture, because some of the paint stands out from the canvas.
Impasto is an Italian word which means "to knead", or "to paste".
Impasto Media
Still Life: Vase with Pink Roses (1890) is an oil painting by Van Gogh which makes extensive use of the impasto technique.
Starry Night by van Gogh (1889). The impasto technique and line structure gives his viewers the feeling that the sky is moving.
Self Portrait by Rembrandt (1660). His use of impasto was surely inspired by Titian, and the addition of impasto showed a new method of illusion in the artist's work.
