Water-Based Pigments, Continued
Casein finishing Paintings painted in casein have a matte or semi-matte surface finish. To
achieve a light gloss on the surface of a casein painting, lightly rub the
surface with a clean, dry, soft cotton ball.
Special
equipment
Special equipment used to create special effects consists of scraping tools,
paper towels or sponges, toothbrushes, atomizers, salt, stencils, or masking
fluids. Experiment with each of these tools.
SCRAPING TOOLS: Scraping tools remove pigment from the paper surface
after you apply it. Scraping tools leave distinct marks according to the type
of tool. Scraping tools include knife blades, razor blades, pins, nails, saw
blades, palette knives, and fingernails.
PAPER TOWELS and SPONGES: Paper towels and sponges soak up excess
pigment and water leaving images all their own. For an interesting effect,
crumple a piece of paper, partially uncrumple it and dab it into the pigment
on the paper surface.
TOOTHBRUSHES and MOUTH ATOMIZERS: You can create spackled
effects of all intensities with a toothbrush or a mouth atomizer. To use an
atomizer, place the straw end into a cup of pigment and blow into the
mouthpiece.
Figure 1-31 shows a mouth atomizer.
