The process Jess uses to create her collection of glass pieces with line drawings sandblasted onto their surface can most accurately be described as ‘glass sgraffito’. This process is an adaptation of a ceramic technique where wet clay is stained and drawings are carved into the surface of the clay creating a two-toned image. In glass, the two-tone image is achieved by blowing a vessel with contrasting interior and exterior colors. The exterior color serves as a skin through which Jess carves, revealing the interior color. Once she has blown the vessel, Jess makes a free hand line drawing on a clear transparency that is specific to the contours and size of the blown piece. Then, using photosensitive film and an exposure device Jess makes a contact print of the drawing onto the film. This film then becomes a resist that gets adhered to the surface of the glass vessel. Lastly, Jess sandblasts the whole surface of the piece and the film protects the exterior glass color where the lines of the drawing are absent.
