Charbonnel Soft Black Ball Ground
Soft Black Ball Etching Ground (solid)
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.
