Supervision Bovine bile

Bovine bile, also known as Ox Gall, is a traditional watercolor medium used to enhance the flow and diffusion of watercolor pigments. It reduces surface tension, allowing paint to spread more smoothly and evenly, especially useful when working with granulating or mineral-based colors.

Key Benefits:

• Improves wetting and flow of colors

• Enhances diffusion and blending

• Helps pigments spread naturally on the paper

How to Use:

• Add 1–2 drops into your clean water container or mix directly with the watercolor on your palette.

• Ideal for creating soft washes, loose effects, and fluid textures

• Use sparingly to avoid over-thinning or losing pigment strength.

Perfect for artists seeking greater control and elegance in their watercolor technique.
