Resin Pigments vs. Alcohol Inks: What Is the Difference?
The problem every new resin crafter hits: you watched a pour video with gorgeous cells, went out and bought mica powder, and your pour looked completely different. No cells, different transparency, different coverage. You spent the next hour trying to figure out what you did wrong.
You didn’t do anything wrong. You used a different type of colorant. That’s it.
Alcohol inks and pigments behave in fundamentally different ways inside resin, and that difference determines your results before you mix a single drop. Here’s what actually separates them.
The Core Difference
Alcohol inks are dye-based liquids. They are alcohol-soluble colorants that disperse in resin by floating, separating, and interacting with heat from a torch or the natural movement of the liquid. That float-and-separate behavior is exactly what creates cells.
Pigments (mica powder, pigment paste, pigment powder) are particle-based. They mix into the resin rather than floating on top of it. They color the resin uniformly throughout whatever volume you mix them into. They do not create cells on their own because there is no separation happening.
Same resin. Same torch technique. Completely different results depending on which you choose.
Side-by-Side: How Each Colorant Behaves
Alcohol Inks: Ranger and Winsor and Newton
I tested Ranger Alcohol Inks and Winsor and Newton Drawing Ink in the same epoxy resin base, same 1:1 mix ratio, same pour conditions, and same torch pass.
Coverage: Semi-transparent to transparent. Light passes through the color layer. The ink sits in the resin rather than coating it.
Cells: Excellent. The alcohol content creates density differences in the resin as it disperses. Add a torch pass and those density differences pop into defined cells. Ranger inks in my experience produce medium-sized cells with soft edges. Winsor and Newton inks are more diluted and tend to form smaller, more numerous cells with more blending at the color edges.
Cure time impact: At standard ratios (5 to 10 drops per oz of resin), alcohol inks don’t measurably affect cure time. At high concentrations above 15 drops per oz, I’ve had cure time extend by 4 to 6 hours on a standard 72-hour system. If you’re layering multiple pours, account for that.
Best for: Ocean art, lacing effects, geode interiors, anything where transparency and movement are the goal.
Alumilite Mica Powder
Alumilite’s mica powders are cosmetic-grade: finely milled reflective particles that suspend throughout the resin.
Coverage: Semi-opaque to fully opaque depending on concentration. At 1/4 tsp per oz of resin you get shimmer with some transparency remaining. At 1/2 tsp per oz the coverage becomes solid and the metallic effect dominates.
Cells: None. Mica particles distribute uniformly through the resin. No separation, no cell formation. If you want cells with mica, layer alcohol ink underneath or alongside it.
Settling: In thick pours over 1/4 inch, mica particles can settle before the resin gels. Stir or torch the surface partway through the gel window if you’re doing a deep pour.
Cure time impact: Minimal at standard ratios. Unlike alcohol, mica powder doesn’t interact with the resin chemistry.
Best for: Metallic accents, geode walls, galaxy pours, any application where shimmer and opacity are the goal.
Art N Glow Pigment Paste
Pigment paste is pre-dispersed pigment in a carrier gel. It mixes smoothly without clumping the way loose powders sometimes do, and it produces the most saturated, opaque color of the three options tested here.
Coverage: Opaque. A small amount produces full, rich coverage. At roughly 2% by weight (a pea-sized amount per oz of resin), you get consistent, even color throughout the pour.
Cells: None. The colorant mixes in rather than floating, same as mica powder.
Best for: Solid color fills, opaque background layers, multi-pour designs where you need a defined base color before adding transparent or metallic layers on top.
Which One Should You Buy First?
If you want cells and movement: Start with Ranger Alcohol Inks. The 20-color set runs about $35 on Amazon and gives you enough variation to experiment with color combinations. Pick up Winsor and Newton Drawing Ink as a second option once you understand how the Ranger inks behave in your resin brand. Different resins have different viscosities, and that changes how cells form.
If you want opaque coverage: Art N Glow Pigment Paste. Their starter 16-color set is around $25. The pre-dispersed formula is genuinely easier to work with than loose pigment powders when you’re learning to control resin ratios.
If you want metallic shimmer: Alumilite mica powder. Their 28-color kit runs about $20. The cosmetic-grade milling is noticeably finer and more consistent than budget mica powders, which affects both the shimmer quality and how evenly it suspends.
The longer answer: you will eventually want all three. Alcohol inks, mica powder, and pigment paste do not compete with each other. They solve different problems within the same pour. Most intermediate resin artists combine them in a single piece: pigment paste for the opaque base, mica for metallic accents, and alcohol inks for the transparent cell layer on top.
The mistake is not buying the wrong one. The mistake is assuming they’re interchangeable.
