Pyrography is the art of decorating wood or other materials with burn marks created by a heated tool. Common techniques include shading, outlining, and stippling. Shading involves varying the pressure and speed of the tool to create depth, while outlining provides clear definitions of shapes. Stippling uses small dots to build texture and detail. Another technique is wood burning, which can be done with different tips on a pyrography pen. Each tip produces unique effects, allowing artists to create intricate designs. Safety precautions, such as working in a well-ventilated area and using protective gear, are essential to prevent inhalation of fumes.
