Gabrielle Moore specialises in the tonal aquatint form of etchings and most of her prints are of this method. Aquatints are achieved by laying a resin dust on a clean blank metal plate, melting it to harden, make it adhere and act as resistant to acid. A stop out varnish is then used in a build-up of steps to create the tonal image. The plate goes through a series of dips into acid to obtain a depth of “biting”. The resulting holes eventually hold the ink for the printing process.
