Sprinkling pumice by hand on paper wet with acrylic gel produced bumps. What would happen if pumice was shaken from a salt shaker. Hmm, still bumpy. Why not sift the pumice through a mesh strainer like flour through a sifter? This should work well over any wet, polymer/acrylic gel, medium or ground. I gave it a try.
When dry, the pumice dusted surface appeared more uniform then previous experiments, but still a unique product of my own hand. Always nice!
Drawing gently on the grit with a charcoal stick left a pleasing, dense line. The pumice dust appeared to be secure, yet had an overall softness. The next question is, “Will this surface withstand multiple layers of pigment?”
