How to Use Mica Powder in Epoxy
Mica powder is one of the easiest ways to add colour, shimmer, pearl effects, metallic movement, and depth to epoxy resin. Whether you are making a river table, resin coaster, serving tray, charcuterie board, ocean pour, inlay, or decorative woodworking project, the way you mix and test your pigment can make a big difference in the final result.
Beaver Dust Pigments are fine mica powder pigments designed to mix smoothly into epoxy resin. All Beaver Dust Pigments are under 60 microns, which helps them stay suspended in epoxy while it cures instead of sinking to the bottom like larger or heavier pigment particles can.

Quick Answer: How Do You Use Mica Powder in Epoxy?
To use mica powder in epoxy, mix your epoxy resin and hardener according to the epoxy manufacturer’s instructions, then add a small amount of mica powder and stir until the colour is evenly blended. Add more pigment gradually until you reach the colour strength, shimmer, and opacity you want.
Always test a small batch before mixing a large pour. The final colour can change depending on the resin system, pour depth, background colour, wood tone, lighting, and amount of pigment used.
Step-by-Step: Mixing Mica Powder Into Epoxy
1. Mix the Epoxy First
Start by mixing your epoxy resin and hardener exactly as directed by the epoxy manufacturer. Proper resin mixing comes first because the pigment will not fix an epoxy batch that was measured or mixed incorrectly.
2. Add a Small Amount of Mica Powder
Add a small amount of Beaver Dust mica powder to the mixed epoxy. A little pigment can go a long way, especially in smaller pours, thinner coats, and lighter colours.
3. Stir Slowly and Thoroughly
Stir the mica powder into the epoxy until the colour looks even. Scrape the sides and bottom of the mixing cup so dry pigment does not stay trapped in one area.
4. Adjust the Colour Gradually
If the colour looks too light or too transparent, add a little more mica powder and mix again. Build the colour slowly instead of adding too much pigment at once.
5. Pour and Watch the Effect
Once the pigment is fully mixed, pour the epoxy into your project. The final look can change as the resin settles, levels, cures, and reflects light from different angles.

How Much Mica Powder Should You Use in Epoxy?
The right amount of mica powder depends on the epoxy system, pigment colour, pour depth, and finished look you want. A small amount can create a soft shimmer or translucent colour, while more pigment can create a stronger, more opaque effect.
The best approach is to start with a small amount, mix thoroughly, and slowly add more until the colour looks right. This gives you better control and helps avoid adding more pigment than the epoxy system can handle.
For large pours, expensive slabs, or a colour you have not used before, make a small test sample first. Testing is the safest way to confirm colour strength, shimmer, opacity, and how the pigment looks after curing.
Why Particle Size Matters When Mixing Mica Powder
Epoxy takes time to cure, so pigment particles need to stay suspended while the resin hardens. If pigment particles are too large or too heavy, they can settle before the epoxy cures, leaving more colour at the bottom of the pour.
Beaver Dust Pigments are under 60 microns, which helps them mix smoothly and stay suspended in epoxy while it cures. This is especially useful for river tables, deep pours, resin art, coasters, trays, charcuterie boards, and woodworking inlays.
Fine mica powder also helps create a more even shimmer because the pigment can distribute more consistently throughout the resin.
How to Control Transparency, Opacity, and Shimmer
For a Light Shimmer
Use a small amount of mica powder if you want the epoxy to stay more transparent while still showing colour and shimmer. This can work well for subtle inlays, clear resin accents, and projects where you still want depth.
For Stronger Colour
Add more mica powder gradually if you want stronger colour, more shimmer, or a more opaque look. This is common for river tables, coasters, trays, and bold resin art.
For Specialty Effects
Ghost pigments, colour-shift pigments, fluorescent pigments, and star series colours may look different depending on the background colour, lighting, pour depth, and viewing angle. Test these effects before using them in a final project.
Best Projects for Mica Powder in Epoxy
Mica powder is useful in many epoxy projects, especially when the resin is meant to be visible in the finished piece.
- River tables: create flowing colour, shimmer, depth, and metallic movement inside the epoxy river.
- Resin art: create swirls, ocean effects, geode effects, galaxy effects, pearl highlights, and metallic accents.
- Coasters and trays: test bold colours, colour-shift pigments, ghost pigments, fluorescent colours, and metallic effects.
- Charcuterie boards: add colour to cracks, knots, voids, handles, and decorative epoxy details.
- Woodworking inlays: use coloured epoxy for logos, bowties, engraved details, lettering, and design features.
- Ocean pours: use blue, teal, green, white, and pearl colours to create water-inspired resin effects.

Choosing the Right Beaver Dust Colour
The right mica powder colour depends on the project style, wood species, epoxy depth, and finished look you want.
Blue, Green, and Teal Pigments
Blue, green, teal, Caribbean, and blue-green colours are popular for river tables, ocean effects, lake-inspired projects, coasters, trays, and water-style resin art.
White, Pearl, and Light Pigments
White, silver pearl, star white, and lighter shimmer colours are useful for waves, highlights, soft shimmer, pearl effects, marble-style looks, and cloudy resin details.
Black, Grey, Bronze, Copper, and Gold Pigments
Dark and metallic colours are useful for smoky resin, modern furniture, black rivers, industrial-style projects, geode effects, luxury accents, and high-contrast designs.
Ghost, Colour-Shift, Fluorescent, and Star Pigments
Specialty pigments are best when you want the effect to change with light, angle, background colour, or viewing position. These are especially useful for sample boards, resin art, coasters, trays, and statement pieces.
Mixing Tips for Better Results
- Mix your epoxy resin and hardener properly before adding pigment.
- Start with a small amount of mica powder and increase gradually.
- Scrape the sides and bottom of your mixing cup so the pigment blends evenly.
- Use a test pour before committing to a large project or expensive slab.
- Check the colour in the same lighting where the finished project will be viewed.
- Remember that deep pours, thin coats, and different backgrounds can change the final appearance.
- Avoid adding more pigment than your epoxy system can handle.

Common Mistakes to Avoid
- Adding too much mica powder before testing the colour.
- Not mixing the pigment thoroughly into the epoxy.
- Choosing a colour without considering the wood tone or background colour.
- Assuming a colour will look the same in a thin coat and a deep pour.
- Skipping a test sample when using ghost, colour-shift, fluorescent, or specialty pigments.
- Using pigment particles that are too large or heavy for the epoxy cure time.
Can You Use Beaver Dust Outside of Epoxy?
Yes. Beaver Dust Pigments are commonly used in epoxy resin, but they are also safe for candle and soap making and can be used in many craft and decorative projects.
Mica powder can also be tested in compatible paint, coating, clear coat, automotive-style finish, and powder coating systems. These applications are more system-dependent, so test Beaver Dust with your exact material and process before using it on a finished project.
Testing first helps confirm colour strength, shimmer, suspension, cure behaviour, and final appearance.
Common Questions About Using Mica Powder in Epoxy
Do you add mica powder before or after mixing epoxy?
Mix your epoxy resin and hardener according to the epoxy manufacturer’s instructions first, then add mica powder and stir until the colour is evenly blended.
How much mica powder should I add to epoxy?
Start with a small amount and add more gradually until you reach the colour strength, shimmer, and opacity you want. Always test before making a large pour.
Will mica powder sink in epoxy?
Some pigment powders can settle if the particles are too large or heavy. Beaver Dust Pigments are under 60 microns and are designed to stay suspended in epoxy while it cures.
Can you mix different mica powder colours together?
Yes. Mixing different mica powder colours can create custom shades, layered effects, and more complex resin designs. Test small batches first so you can see how the colours blend and cure.
Can Beaver Dust be used for candles and soap too?
Yes. Beaver Dust Pigments are safe for candle and soap making, making them useful beyond epoxy resin projects.
