Charbonnel Soft Black Opaque Etching Grounds Ball provides etching grounds in solid form.
These soft grounds are non-drying. They deliver soft lines and textural effects.
This etching ground is best applied to warm plates with a leather dabber or a brayer. As this is soft ground, you can use the pencil method to make imprints on your plate.
To achieve the pencil method, apply a light sheet of paper over the prepared plate. Next use a hard pencil to draw out your design. When the paper is removed it will take the pressured lines of ground with it, leaving the drawing on the plate.
