What is the difference between etching and aquatint?

The difference between etching and aquatint is technique. Invented in the 1500s, etching is a way of incising lines in a metal plate by first drawing on an acid-resistant coating, or ground, to reveal the metal beneath. The plate is then submerged in acid, which “bites” the lines into the metal plate. The ground is then removed, and the plate is inked for pressing. Etched lines tend to reveal the movement of the artist’s hand more than a technique like engraving, since the image is created on softer ground. Aquatint, a technique named for its resemblance to watercolor or ink wash, is often combined with etching to create rich tonal variations. It’s a similar process to etching, but the resin ground is more granulated, so the acid handles the metal differently. Different degrees of darkness are created based on the amount of time the plate is in contact with the acid. Find a collection of etchings and aquatint prints on 1stDibs.
