Glossary

• Engraving

  An intaglio process whereby lines are cut into a metal or wood plate using an engraving tool (a burin), which is pushed in front of the hand to achieve a sharp controlled incision capable of great delicacy. This technique requires a great deal of control and is not suited to spontaneous mark-making.

• Etching

  An intaglio process whereby a metal plate (normally copper, zinc or steel) is covered with an acid-resistant layer of rosin mixed with wax. With a sharp point, the artist draws through this ground to reveal the plate beneath. The plate is then placed in an acid bath (a water and acid solution) and the acid bites into the metal plate where the drawn lines have exposed it. The waxy ground is cleaned off and the plate is covered in ink and then wiped clean, so that ink is retained only in the etched lines. The plate can then be printed through an etching press. The strength of the etched lines depends on the length of time the plate is left in the acid bath.

• Painting

  Work of art made with paint on a surface. Often the surface, also called a support, is a tightly stretched piece of canvas, paper or a wooden panel. Painting involves a wide range of techniques and materials, along with the artist's intellectual concerns effecting the content of a work.
