Art Informel is a French term referring to the gestural and improvisational techniques common in abstract painting during the 1940s and 50s. It encompasses various styles that dominated these decades, characterized by informal, spontaneous methods. Artists used this term to describe approaches that moved away from traditional structures and embraced more expressive, unstructured techniques.

Oil on board is a painting technique where oil paint is applied to either wood panels that have been sanded and primed or high-density cardboard covered with canvas. These surfaces offer the advantage of being more compact for storage compared to traditional stretched canvas on frames, while still providing a stable surface for painting.

Matter painting is a technique that involves blending thick impasto paints with materials like cement, mud, sand, or shells. The term first emerged in the 1950s to describe the works of Belgian and Dutch painters who explored the physical properties of painting materials and the different ways paint could be manipulated. This approach emphasizes texture and the tactile qualities of the surface, creating a sculptural effect on the canvas.
