Faktura
The concept of faktura is associated with Russian Constructivism. In the period after the Russian Revolution, new definitions of art had to be found, such as the definition of art objects as "laboratory experiments". "Fakture" was the single most important quality of these art objects, according to the critic Victor Shklovsky, referring to the material aspect of the surface. The surface of the object had to demonstrate how it had been made, exhibiting its own distinct property.
Faktura-The visual demonstration of properties inherent to materials.
