Nora Schattauer (* 1952 in Duisburg) works with chemical solutions, mineral salts and acids, which are applied to the paper in a controlled manner with a pipette, in such a way that an almost regular, constantly varied pattern forms the basic framework. As the substances penetrate the image carrier, they gain visual depth and thus become a kind of physical resonance surface. They react with the unglued paper, form bonds and are subject to subsequent colour changes. This "reaction process" often gives the works a fluid character; the artist herself speaks of "controlled chance". Although Schattauer cannot completely anticipate the result, empirical values allow her to control it in a variety of ways.
