Pyrography or pyrogravure is the free handed art of decorating wood or other materials with burn marks resulting from the controlled application of a heated object such as a poker. It is also known as pokerwork or wood burning. The term means "writing with fire", from the Greek (fire) and (writing). It can be practiced using specialized modern pyrography tools, or using a metal implement heated in a fire, or even sunlight concentrated with a magnifying lens. "Pyrography dates from the 17th century and reached its highest standard in the 19th century. In its crude form it is pokerwork." Pyrography is also popular among gourd crafters and artists, where designs are burned onto the exterior of a dried hard-shell gourd. History Pyrographer Robert Boyer hypothesizes that the art form dates back to prehistory when early humans created designs using the charred remains of their fires. It was known in China from the time of the Han dynasty, where it was known as "Fire Needle Embroidery". During the Victorian era, the invention of pyrography machines sparked a widespread interest in the craft, and it was at this time that the term "pyrography" was coined (previously the name "pokerwork" had been most widely used) In the late 19th century, a Melbourne architect by the name of Alfred Smart discovered that water-based paint could be applied hot to wood by pumping benzoline fumes through a heated hollow platinum pencil. This improved the pokerwork process by allowing the addition of tinting and shading that were previously impossible. In the early 20th century, the development of the electric pyrographic hot wire wood etching machine further automated the pokerwork process, and Art Nouveau pyrographic gloveboxes and other works were popular in that era. Pyrography is a traditional folk art in many parts of Europe, including Romania, Poland, Hungary, and Flanders, as well as Argentina and other areas in South America. Equipment Traditional pyrography can be performed using any heated metal implement. Modern pyrography machines exist, and can be divided into three main categories. A large range of tones and shades can be achieved. Varying the type of tip used, the temperature, or the way the iron is applied to the material all create different effects. After the design is burned in, wooden objects are often coloured. Solid-point burners Solid-point burners are similar in design to a soldering iron. They have a solid brass tip which is
