Winsor & Newton Ox Gall Liquid 75ml

Winsor & Newton Ox Gall Liquid is a professional wetting agent that transforms how watercolour behaves on paper. By reducing surface tension, it allows pigments to flow more freely, blend more smoothly, and settle more evenly.

Simply add a few drops to your water or mix directly with paint. Not only does it improve spread on hard-sized papers, but it also enhances control in wet-on-wet techniques. Because it helps paint glide effortlessly, artists can achieve luminous washes and subtle transitions with ease.

Moreover, Ox Gall is especially effective on papers with minimal sizing, where paint tends to resist movement. Whether you’re working with Fabriano, Arches, Saunders, or Aquafine papers this medium ensures consistent, professional results.

In addition to improving flow, it also supports layering and glazing. As a result, artists can build depth without disturbing underlying layers.

Key Benefits:

• Enhances watercolour flow and blending
• Reduces surface tension for smoother washes
• Ideal for hard-sized and minimally sized papers
• Supports layering and wet-on-wet techniques
• Compatible with all professional watercolour brands

Packaged in a 75ml bottle, it’s perfect for studio or travel use. After painting, rinse brushes with water. For best results, experiment with ratios to suit your style.
