Verdigris Step-by-step
1.
Prime and paint the surface black.
2. Dilute all paints with
water (one part paint to two parts water)
Dampen a sea sponge in water and dip one corner of the sponge
into the diluted dark green mixture. Sponge the surface in
a random pattern. Repeat sponging process using diluted medium
blue-green paint and diluted pastel green paint. Finish by
sparingly sponging diluted raw sienna paint onto the surface.
3. To give the finish
the texture and depth of patina, hold the container of powdered
plaster 10-12 inches about the sample. Lightly sprinkle plaster
on the surface.
4. Using a sponge, lightly
dab the colors and plaster, moving in a diagonal direction.
Do not over work the sample or create obvious patterns.
5. Let dry. Wipe the surface
firmly with a cotton rag to create a flat, chalky finish.
Variations
on a theme
Create the look of copper patina by using copper paint and
a mild acidic solution. This process actually oxidizes copper,
creating a rich blue-green finish.
