Etching grounds and covering varnishes Charbonnel

Traditional etching grounds and retouch grounds can contain the following ingredients: Bitumen from Judea (asphalt), terpentine, wax, dammarresin, petrol, colofonium and tar. It is used to cover the etching plate, making it resistent during etching. After covering the plate with the ground (by roller or brush), the drawing in made in the ground. Covering varnishes are made to cover the non image side of the plate, but some sorts are also used to cover parts of the image side during fased etching.

CHARBONNEL Hard black ball ground.

Wrapped in a piece of taffeta which serves as a filter, the ball is rubbed on the pre-heated metal plate. Dab on the ground to obtain an even surface before smoking. The matt black finish obtained makes etching work very clear. Once the ground is applied and dry, the picture is drawn with a hard point in order to expose the metal beneath the ground. The plate is then placed in a bath of acid to erode the exposed metal. Once the required bite depth has been attained, the plate should be taken out of the acid bath solution and dried and the ground removed with the appropriate thinner:

  • Judea bitumen, wax
  • Dry extract: 100%
  • Hardness: very hard
  • Finish: opaque matt
  • Consistency: paste

CHARBONNEL Soft black ball etching ground

A painting dabber is recommended for application. It is applied hot. Soft grounds protect the plate. They are non-drying grounds, applied with a painting dabber or roller: Textures and materials pressed into their non-drying surface will lift off, leaving the metal bared, ready for the bite of the acid. The plate must be heated before application. The "Pencil Method" consists of drawing with a hard point on "laid" paper applied over the soft ground. The paper sticks to the drawn parts. After the bite of the acid, a pencil stroke effect is obtained.

After leaving the plate in acid for the required time, remove the plate from the acid bath solution and remove the ground using the appropriate thinner. The amount of time you leave the plate in the acid depends on the acid's strength (mesured using an acetometer), the room temperature and the depth you wish to give the stroke. The etching is then ready and only the finishing touches need to be applied. A retouching ground can be applied to the plate which may then be retouched as required following the lines of the previous etching.

It is applied cold with a paintbrush. It is slow-drying and lets the previous etching show through.
