What is a burin used for in printmaking?

A burin is a specialized tool traditionally used in printmaking, particularly in the technique known as engraving. Its primary function is to engrave or carve designs into metal plates, such as copper or zinc, which are then used to create prints. The sharp, pointed end of the burin allows the artist to make precise and controlled lines, resulting in detailed images when inked and pressed onto paper.

This technique is distinct from the other options presented. Applying ink pertains to inking rollers or brayers, which are not related to engraving. Creating textures in clay involves tools like modeling tools or carving knives rather than a burin, and shaping glass is typically done with tools specific to glasswork, such as glass cutters or grinders. The engraving process using a burin is fundamental in printmaking, which allows artists to produce multiple copies of their work with intricate designs.
