An intaglio process of biting into metal plates using a solution of copper sulphate. A ‘ground’ is applied to the plate and then drawn into using an etching needle. The plate is then put into the copper sulphate. Where the plate is exposed, the chemical will bite away at the metal. Tone can be achieved by leaving open areas on the plate in the copper sulphate for differing lengths of time. To print, ink is wiped into the bitten areas and then the plate is printed onto damp paper which presses into the plate and lifts the ink away. Etching is particularly suitable for drawn tonal images.
All images shown here have been produced at the workshop.
