Burr_(metal) | TriviaQuestions.online

⭐ In the context of drypoint, a burr—the raised ridge of metal displaced during the incising process—is considered…

The burr created in drypoint is not removed, unlike in engraving, and this fragility means the plate wears down quickly, resulting in a limited number of usable impressions.

⭐ Core Definition: Burr (metal)

A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring. Burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or turning. It may be present in the form of a fine wire on the edge of a freshly sharpened tool or as a raised portion of a surface; this type of burr is commonly formed when a hammer strikes a surface. Deburring accounts for a significant portion of manufacturing costs.

In the printmaking technique of drypoint, burr, which gives a rich fuzzy quality to the engraved line, is highly desirable—the great problem with the drypoint medium is that the burr rapidly diminishes after as few as ten impressions are printed.

👉 Burr (metal) in the context of Drypoint

Drypoint is a printmaking technique of the intaglio family, in which an image is incised into a plate (or "matrix") with a hard-pointed "needle" of sharp metal or diamond. In principle, the method is practically identical to engraving. The difference is in the use of tools, and that the raised ridge along the furrow is not scraped or filed away as in engraving. Traditionally the plate was copper, but now acetate, zinc, or plexiglas are also commonly used.

Like etching, drypoint is easier to master than engraving for an artist trained in drawing because the technique of using the needle is closer to using a pencil than the engraver's burin. The incision into the plate is also typically much more shallow, so requiring less effort and technical skill in the use of the engraver's burin, but meaning that fewer impressions (copies) of a print can be pulled before wear to the plate becomes apparent. Modern limited editions of drypoint prints (if not steelfaced) very often have fewer than thirty impressions.
