Can I Achieve Translucent and Opaque Effects with Epoxy?

Understanding Translucent and Opaque Resin Effects

The difference between translucent and opaque effects lies in your choice—and amount—of resin pigment. Translucent effects let light pass through, creating a stained-glass, layered appearance. Opaque effects, on the other hand, are solid and block light entirely for a bold, uniform finish.

For a subtle wash or sea-water effect, use only a small amount of highly concentrated colourant, such as Colourfun liquid epoxy resin colourant. To make your resin completely opaque, increase the quantity of pigment or opt for specially formulated sets designed for solid coverage, for example, the Colourfun Set for Solid Colour Effects.

How to Create Custom Effects

Begin with clear, mixed epoxy resin, and add drops of pigment gradually, stirring carefully. Always test opacity with a small sample—pigments are often highly concentrated, so a little goes a long way. For richer, denser colour, build up pigment slowly to avoid over-saturation, which could affect curing.

• Combine different shades for unique tones.
• Use metallic or marine pigments to enhance depth or evoke nature-inspired visuals.
• Keep thorough notes on quantities for consistent future results.

When This Matters

Choosing between translucent and opaque effects is especially important in jewellery, coasters, river tables, and art panels. Translucency adds dimension and can mimic water or glass, while opacity brings drama and impact to your finished piece.
