The name of this technique derives from the mix of water and acid that was traditionally called “acquaforte”, meaning strong water.


The technique is done by covering the metal plate with a anti-acid varnish, such as bitume or the satinated varnish, and later on creating a design on the plate with any type of pointed instrument.


After covering the back and the edges of the plate with an adhesive plastic, the metal plate is submerged in the acid allowing the exposed part of the metal to be corroded by the acid, controlling the depth of the drawing with the intensity of the acid and the time it is left in the acid. The longer the plate is left in the acid, the deeper the line will be and therefore the darker it will come once it is stamped.
