To Create a Detonograph
Dec 21, 2007
Evelyn works with the Energetic Materials Research and Testing Center (EMRTC), located at the New Mexico Institute of Mining and Technology in Socorro, New Mexico where, in 1986, with the support and cooperation of the Center, she developed the technique for creating the detonographs. The technique, which uses a sandwich of explosive material and metal sheets placed upon a clay mold, forms the basis for her art. The inclusion of natural objects, such as leaves, feathers, or pieces of fur placed between the sandwich and the mold add interest to the resulting sculpture and has given her the freedom to create art whick is unique and could be created in no other way.
Evelyn takes advantage of three characteristics which occur in the blast to create her images. First, the metal is formed over a plaster mold of three-dimensional design by the tremendous pressure of the explosive which is traveling at 27,000 ft/sec. Second, due to the force of the explosion, dissimilar metals are pressure welded together by the pressure of the blast. Third, real objects such as lace, leaves, or other textures placed between the explosive and the metal plate are impressed into the surface of the plate.
