At the beginning of the 20th century, traditional art began to experience a change in its understanding. When the progress of this process, the diversification of social life, and the change in military and political policies are evaluated, each of them has had a direct or indirect impact on art. Especially, the traditional shell of developments in the field of technology has been broken and irregular and unusual works have begun to emerge, and the bond between the work of art and the audience has changed. Thus, commercial paintings containing very different materials and technology have turned into paintings containing deviations, that is, anomalies. Especially from the 1950s until today, many artists have produced very advanced and fragmented works and have completely examined traditional methods. In this research, studies were made on the plastic of the painting in the context of the use of materials in the works of Robert Rauschenberg and Anselm Kiefer.
