The electro-etching courses offered by Alfonso Crujera are intended for professional or amateur printmakers, teachers, and students of art and etching.
Electro-etching is a technique discovered in the nineteenth century, recently re-discovered as a non-toxic printmaking alternative. It offers one of the most healthy and interesting methods for etching copper, zinc, and iron plates. Among other advantages, the electro-etching process does not generate toxic gases, nor does it produce wastes on the metal during etching. The mordant does not exhausted by successive bites and it does not undercut the metal under the varnish. It completely eliminates the use of harmful spray resin or asphalt for aquatints.
Alfonso Crujera offers two different courses.
