Lamour Harde etching ground, black ball.
This ground is slightly less hard a the Charbonnel Hard Black Ball Ground, but use the same method to apply the ground to the plate. 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:
