Charbonnel Lamour Black Satin Ground 75ml
It allows a long etching time with no risks of scaling.
Apply it cold to the plate with a very supple brush, or plate coating device or pour it directly onto the inclined plate.
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.
