How to Stop Colour Settling in Resin for Uniform Results

Why Pigment Settling Occurs in Resin

Pigment settling happens when colour particles, especially those not designed for resin, gradually sink during curing. This creates uneven, streaky, or patchy colour, particularly visible in clear or transparent projects. It’s a common issue when using powders or standard craft pigments not formulated for resin applications.

Choosing the Right Colourants for Uniform Colour

Specialist resin dyes like the Magic Crystal Transparent Resin Colour range are engineered to disperse fully and remain suspended, preventing settling. These liquid dyes blend smoothly into transparent resin, allowing vibrant colour while preserving glass-like clarity—ideal for geode, gemstone, and jewellery effects. Paste-based colourants such as Colourfun also deliver streak-free, uniform tints in opaque or translucent finishes.

• Choose resin-specific liquid or transparent dyes for even results
• Always mix pigment and resin thoroughly before casting
• Stick to product recommendations for ratios—too much pigment can affect curing and settling

When Uniform Colour Matters Most

Uniform colour is particularly important in jewellery, crystal replicas, layered projects, and deep castings where any streak or mottling becomes noticeable. Opting for non-settling pigment solutions gives you confidence in the final finish on display pieces or clear castings.
