Best Pigments for Epoxy River Tables

Pigments are the heart of a beautiful river table. They create motion, depth, metallic effects, swirling patterns, and the signature “river flow” that makes these tables so unique. Choosing the right pigments can completely transform your project from subtle transparent shading to bold metallic river currents.

This guide breaks down the top pigment types, professional techniques, and recommended combinations for stunning river table results in 2025.

Why Choosing the Right Pigment Matters
– Affects clarity and depth
– Controls flow and movement
– Creates shimmering or solid effects
– Impacts overall curing behavior
– Determines UV stability long term

Types of Pigments for River Tables

1. Mica Powders
Mica is the most popular choice for river tables. It creates metallic, pearl, and shimmering effects that move beautifully in deep pours.
Benefits:
– Rich metallic shine
– Easy to control
– Does not fade
– Works perfectly in DeepFlow resin

2. Liquid Epoxy Pigments
These provide solid or semi-transparent colors without metallic sheen.
Great for:
– Solid rivers
– Opaque designs
– Minimal swirl movement

3. Alcohol Inks
Perfect for cloud effects and soft gradients.
Best used:
– In thin pours
– For artistic shading
Note: Too much can weaken resin; use sparingly.

4. Glow Powders
Ideal for night-time effects.
Glow pigments create:
– Neon highlights
– Glowing rivers in dark rooms
– Striking contrast with black mica

Best Pigment Color Combinations for River Tables
– Black + Silver Metallic
– Deep Blue + White Pearl
– Emerald Green + Gold
– Teal + Sapphire Blue
– Copper + Black
– Transparent Aqua + Silver

How Much Pigment Should You Use?
General rule:
– 1–2% pigment by epoxy volume

Too much pigment can:
– Cause soft cures
– Reduce clarity
– Create streaks

Professional Techniques for Amazing Effects
– Pour two colors side-by-side
– Drag a stick through to create currents
– Heat lightly for movement
– Alternate transparent and opaque pigments

Final Thoughts
Pigments are where creativity truly begins. With the right combinations and a high-quality deep-pour resin, your river table will have depth, clarity, and movement worthy of a professional build.
