A ground is waxy material applied to the surface of a metal etching plate. A metal etching plate is a piece of sheet metal, usually copper, zinc, steel, or aluminium.The ground resists the acid or mordant which is used for etching, protecting areas of the metal plate.
Etching by Jacques Bellange, Gardener with basket c. 1612. Callot also appears to have been responsible for an improved, harder, recipe for the etching ground, using lute-makers' varnish rather than a wax-based formula. This enabled lines to be more deeply bitten, prolonging the life of the plate in printing, and also greatly reducing the risk ...
The artist applies a ground that will resist acid. Ground is applied by dissolving powdered resin in spirits, by applying the powder directly to the surface of the plate, or by using a liquid acrylic resist. In all forms of etching the acid resist is commonly referred to as "the ground." An aquatint box is used to apply resin powder.
The plate's ground side is then dipped into acid, or the acid poured onto it. The acid bites into the surface of the plate where it was exposed. Biting is a printmaking term to describe the acid's etching, or incising, of the image; its duration depends on the acid strength, metal's reactivity, temperature, air pressure and the depth desired.

Etching is part of the intaglio family. In pure etching, a metal plate (usually copper, zinc, or steel) is covered with a waxy or acrylic ground. The artist then draws through the ground with a pointed etching needle, exposing the metal. The plate is then etched by dipping it in a bath of etchant (e.g. nitric acid or ferric chloride). The ...
