Engraving techniques involve carving designs into a hard surface, often using tools like burins or lasers. This art form can be applied to various materials, including metal, wood, and glass. One popular method is intaglio, where the design is incised into a plate, allowing ink to fill the grooves for printing. Another technique is wood engraving, which uses a block of wood to create images. Artists carve away the areas around their design, leaving the raised parts to print. Both methods allow for intricate details and are widely used in creating illustrations, jewelry, and decorative items.
