The zinc plate in an acid bath creates crazy animated forms - very addictive to watch but not good for breathing!! This bath is part of a color viscosity printing process, trying to create distinct layers. Deep etching happens if the plate is left in acid for a long time. Acid eats into a layer of the zinc plate leaving the black painted areas intact -creating distinct layers. #zincplate #etchingplate #viscocityprinting #printmaking (at ArtBuzz) https://www.instagram.com/p/BxfONXljAmp/?utm_source=ig_tumblr_share&igshid=jlfbe4gltbho
