Pyrography — derived from the Greek pur (fire) and graphos (writing) — has been around since fire itself. While there isn’t hard evidence, it’s quite likely that cavemen etched the walls of their caves with fire sticks. While today it’s primarily done on wood with a heated pen, it’s been done (and continues to be done) on leather, clay, and even gourds. Historically, it was used to decorate and brand various tools and musical instruments. Kitchenware or folk guitars were marked with a little bit of art both to convey the owner’s personality, and to distinguish their stuff from other people’s. It wasn’t really until the late Victorian era that the art form was taken up in earnest, and done on blank “canvasses” of wood and other materials rather than being a decorative embellishment.
