When creating a(n) artist draws on a metal plate with a tool called a a. (1) drypoint; (2) burr b. (1) aquatint; (2) needle c. (1) engraving; (2) pick d. (1) etching; (2) gouge

The correct answer is a.  (1) drypoint; (2) burr.

Explanation:

Dry point engraving is a technique similar to that of burr engraving. The artist draws the image on a sheet of zinc, copper, untreated, or acrylic or plastic using an instrument that looks like a pencil, with a diamond tip, or simply sharp metal. As the incision is made a groove is produced, raising on both sides a kind of soft metal crests called "burrs" or "burrs". Burrs can occur on one side of the line or groove, or on both sides, depending on the angle of attack (tip inclination) with respect to the surface. If working at an angle of approximately 45º, the burr is made over the complementary angle. If working at about 90º, the perpendicular tip of the surface, land will be burr on both sides of the line.

These burrs retain a certain amount of ink and give the dry tip stroke a rich and velvety appearance. But if you want to give a firm and clear appearance, it is best to remove burrs, without damaging the groove. The burrs are delicate and wear out with the continuous press of the press so they do not allow runs of more than 20 or 30 copies. To reduce the wear of burrs, which also occurs during the process of inking and cleaning the ink, it is possible to subject the plate to an electrolytic bath, which provides a harder metal. This process is called steel.
