Artists using this technique include Albrecht Dürer, Rembrandt, Francisco Goya, Wenceslaus Hollar, Whistler, Otto Dix, James Ensor, Edward Hopper, Käthe Kollwitz, Pablo Picasso, Cy Twombly, Lucas van Leyden thumb|right|Rembrandt, Christ Preaching, (The Hundred Guilder print); etching Etching is part of the intaglio family. In pure etching, a metal plate (usually copper, zinc, or steel) is covered with a waxy or acrylic ground. The artist then draws through the ground with a pointed etching needle, exposing the metal. The plate is then etched by dipping it in a bath of etchant (e.g. nitric acid or ferric chloride). The etchant "bites" into the exposed metal, leaving behind lines in the plate. The remaining ground is then cleaned off the plate, and the printing process is then just the same as for engraving.
