Process: Electrostatic Thermal

The processes in this section are not based on machinery alone; in fact they focus primarily on the use of silver oxide powders and readily available equipment. In the Generative Systems course entitled Process I, Sonia Sheridan initiated her students to static electricity conductor materials through a variety of practical exercises. One of these consisted of rubbing a Plexiglas panel with a piece of fur (which gave it a positive charge) and then positioning the panel above a container filled with negatively charged particles of silver oxide. A sheet of tracing paper was then placed on the panel to capture the image (a). In another exercise, Sheridan slid a sheet into the Haloid Xerox charging unit to produce patterns that were either dendritic (positive charge) (b) or circular (negative charge) (c). Parallel to the electrostatic processes, thermography was also explored by Sheridan in her Process I course. In order to visualize the effect of heat coming into contact with a chemically treated surface, she placed objects on paper from the C-in-C and exposed it to various thermal sources (d).
