What is the primary medium used in Piet Mondrian's "Tableau 2"?

Piet Mondrian's "Tableau 2" is predominantly created using oil on canvas, which was the primary medium he favored throughout much of his career. This choice of medium allowed him to achieve the clarity and precision necessary for his geometric compositions. Oil paint has the unique ability to render vibrant colors and maintain a smooth surface, which aligns with Mondrian's pursuit of pure abstraction and balance in his work. The characteristics of oil on canvas facilitate the juxtaposition of bold colors and the defined grid structure that are hallmarks of Mondrian's style, particularly in his later works where he explored the reduction of forms to their simplest elements. As such, recognizing oil on canvas as the medium reveals the technical and aesthetic considerations that underpin Mondrian's artistic intentions in "Tableau 2."
