QoR Synthetic Ox Gall, 59ml

QoR Synthetic Ox Gall is a specialised additive designed to improve the flow and wetting properties of watercolour paints. By reducing surface tension, it allows paint to spread more evenly across the paper, making it particularly useful for large washes and smooth gradients.

This medium provides greater control over paint behaviour, helping artists achieve consistent coverage without streaking or patchiness. It is especially effective when working on harder-sized papers where paint may otherwise resist spreading.

Key Features
• Improves paint flow and surface wetting
• Reduces surface tension for smoother washes
• Enhances blending and colour transitions
• Ideal for large-scale applications
