Make your own watercolours with this Watercolour Binding Medium.
This product contains gum arabic, honey, water, and a preservative. When mixed with dry pigments, it provides a smooth, water-soluble paste with a honey-like consistency.
The binder medium will also maintain the watercolours transparency and brilliance. Thin with water (to increase the binders fluidity, add 5 to 10per cent water maximum).
