The works in Christian Rudolph's "Tektonit" (tectonite) series are the result of playful experiments, which the artist initially conducts using paper models. In an abstraction process, he separates geometric surfaces - usually trapezes, but also ovals and ellipses - deforming them, reassembling them, and transferring the results into wall reliefs made of four-millimeter thick aluminum sheets. The surfaces and ridged seams of the fragments are first sanded by hand with extreme precision, after which the relief surface is painted with a coat of monochrome paint as many as a dozen times. The painted surface is then carefully sanded until it has reached a uniform, velvety matt quality. It is only when examined up close that the traces of this process are revealed in the fine scratches on the paint. As with Christian Rudolph’s other works, in the "Tektonit" series both the artistic and the analytical/technical approaches are of equal importance, constituting the two anchor points of his sculptural oeuvre.
