The history and technique of the cliché-verre from its discovery during the first half of the 19th century to the present are discussed. The most important body of works in cliché-verre are those prints of the Barbizon school artists: Corot, Daubigny, Millet, and Rousseau. To produce these prints, collaboration between artist and photographer was necessary. Using etching needles, pointed sticks, and metal brushes, the artist drew on a glass plate that had been coated with an opaque substance. Where this layer was scratched away, light could pass through the plate and expose paper impregnated with silver salts. Printing and development were left to the photographer. An alternative technique of painting images on the glass with oils is also described. Although seemingly obsolete, cliché-verre was revived by contemporary printmakers during the 1950's. Their innovations, such as color cliché-verre and the veil technique, are described. -- AATA
