Decalcomania
Decalcomania is a surrealist technique originated by Oscar Dominguez (and called by him "decalcomania with no preconceived object") in 1936 in which gouache is spread thinly on a sheet of paper or other surface (glass has been used), which is then pressed onto another surface such as a canvas. Black gouache was originally used, though colours later made their appearance. And the production of decalcomanias has not been defined to gouache; at Yale University fingerpaint decalcomanias has been analysed for their tendency, when the process is repeated several times on the same paper, to generate fractals.[1] Max Ernst also practiced decalcomania, as did Hans Bellmer and Remedios Varo.[1]Richard Genovese originated the practice of photographic decalcomania, in which photographic scans are superimposed on decalcomanias.
A variation of this procedure in which paint is applied to a paper, the paper then being folded, is popularly practiced (though without surrealist intent) by young schoolchildren.
