Colorless glass; machine made. The three-dimensional image of the Ennion Cup in the collection of The Corning Museum of Glass has been created by artists and scientists using laser technology. First a digital image of the cup is created; the surfaces of the cup are defined as a "dot cloud" of points in three-dimensional space. A laser beam, guided by computer, is shot into a solid block of optical-quality crystal and programmed to focus for a milli-second on each of the thousands of pre-determined points, creating minute fractures inside the glass. The result is an exquisitely detailed image that appears to be suspended inside the glass block. Black laquered wooden base.
