When working with epoxy resin, control over colour intensity can completely transform your creation. Whether you aim for a solid, opaque finish or a gently translucent look, choosing the right colourants and techniques is key.
Getting a Completely Opaque Finish
For striking, fully opaque effects, opt for high-coverage pigments such as the Colourfun Set. These liquid pastes are intensely pigmented—just a few drops will turn clear resin into rich solid colour. Ensure you blend thoroughly to prevent streaks and achieve a smooth, uniform appearance. Experiment with white, black, and vibrant tones, or mix pastes to obtain bespoke shades like custom grey.
Creating Softly Translucent Effects
If you prefer a finish that gently diffuses light, translucent dyes are ideal. Adjust the number of pigment drops: a light touch with a vivid product like Colourfun, or use a dedicated transparent colourant such as the Magic Crystal Set. This approach allows you to create stained glass, layered river tables, and subtle crystal-inspired pieces that let light pass through beautifully.
Practical Tips for Success
- Always test your blend on a small sample before a large pour.
- Start with less pigment—you can gradually add more to deepen colour or increase opacity.
- Mix colours within the same product range to ensure compatibility and even results.
- For custom shades, blend white and black pigments as a base, or try fine metallic powders for unique effects.
When Opacity or Translucency Matters
Choosing between a solid or translucent finish matters for functional and aesthetic reasons. Opaque resins are great for art panels or hidden surfaces, while softly translucent effects shine in jewellery, lamps, and decorative accents where light interaction is desired.
