Description

Black Matte Opaque Finish.
Dries very hard. Allows for fine detail, deeply etched lines, and clear drawn lines.

How To Use: 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 matte black finish obtained makes etching work very clear.

Plate Cleaning: Before applying these grounds, it is imperative that all grease be removed from the plate.

  • To do this, thin some Marly white (whiting) with a small quantity of water and rub the plate with a soft cloth or a piece of cotton.
  • Rinse under flowing water.
  • Pour a soured solution of vinegar and salt on the plate.
    Rinse once again.
  • Dry rapidly.
  • Avoid putting fingers on the plate whilst carrying out these operations.

Hard Grounds:

  • Once the ground is applied and dry, the picture is etched 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.
