CLICH-VERRE

also called Glass Print, print made by placing photographic paper beneath a glass plate on which a design has been scratched through a coating of an opaque substance and then exposing it to light. The fluid lines possible with clich-verre prints are reminiscent of etched lines. The technique was popular in the 1850s with such French artists as Camille Corot, Jean-Franois Millet, Thodore Rousseau, and Eugne Delacroix. The most prominent 20th-century exponent of clich-verre was the Hungarian-American designer Gyorgy Kepes, who carried out many innovations in the medium, such as painting the glass with mutually repellent substances to achieve infinitely variable effects.
