(noun) - A painting technique, impasto is a thick application of paint (usually oil) that makes no attempt to look smooth. Instead, impasto is unabashedly proud to be textured, and exists to show off brush and palette knife marks. Just think of nearly any van Gogh painting to get a good visual.
Examples: "I continue to get further away from the usual painters tools such as easel, palette, brushes, etc. I prefer sticks, trowels, knives and dripping fluid paint or a heavy impasto with sand, broken glass or other foreign matter added."
- Jackson Pollock
