Note: Cerography or glyphography is a printmaking technique related to engraving, using a layer of wax over a metal substrate. After the image is engraved into the wax, a positive plate is produced through stereotyping or electrotyping. This plate can be used with conventional letterpress equipment. The technique remained popular to the end of the 19th century but was gradually pushed out by photoengraving
