An artist might use the granular effect to suggest the rough bark of an ancient tree, the rough surface of a rocky mountainside, or the chaotic energy of a stormy sky. Conversely, sprinkling salt onto a damp or nearly dry wash produces smaller, more controlled, and granular textures that resemble cork or coarse sand.
Addressing Staining Pigments and Salt Texture Issues
Work on a protected surface, as the process can be slightly messy. Integrating common table salt into watercolor painting introduces a straightforward yet remarkably effective method for creating organic, textured effects.
When granules are sprinkled onto a wet watercolor layer, they begin to pull water and dissolved pigment away from the application site toward their dry, granular core. By disrupting the even spread of pigment, salt generates unique crystalline patterns and mott textures that add a compelling layer of complexity to otherwise flat washes.
Addressing Staining Pigments and Salt Texture Issues
For stubborn grains, lightly tapping the surface is often more effective than rubbing, which can risk disturbing the delicate dried pigment. Granulating pigments, such as those derived from earth colors or certain blues, are particularly effective at producing dramatic crystalline structures.
