Gives a flocculation effect (mottled appearance) to watercolours that usually have a smooth wash (e.g. Winsor Blue) or increases the effect of granulating colours (e.g. French Ultramarine)
For most effective results use generously on its own to dilute watercolour paints and always work with paintings on a flat surface.
