Winsor & Newton Granulation Medium (75ml) (For Watercolour)

With its low-viscosity formula, Granulation Medium gives a mottled appearance to colours which usually produce a smooth wash (for example, Winsor Blue), and will further enhance the effect in granulating colours (like French Ultramarine). For maximum effect, dilute colour with medium alone, or tone the effect down for a more subtle texture by combining with water.
