Mixing Pigments in Resin – Mica, Pastels, Alcohol Inks & More

Introduction

Colour is where the magic happens in resin art. Whether you're making jewellery, coasters, or trays, your choice of pigment transforms clear resin into something truly eye-catching.

But not all pigments work well in epoxy and using the wrong type or too much can lead to bubbles, curing issues, or a dull finish.

In this blog, we explain how to use mica powders, pastels, alcohol inks, liquid pigments, and more with Mycast Epoxy Resin, so you get vivid, professional-looking results.

Pigment Types You Can Use in Resin (and How)

1. Mica Powder

• Finely ground, shimmery pigments that mix easily with resin
  

• Great for metallic, pearlescent, or ocean-inspired effects
  

• Compatible with all Mycast variants
  

How to Use:
Add a small pinch per 30–50g of resin. Mix thoroughly to avoid clumps. For better dispersion, pre-mix with a small amount of resin before combining with your full batch.

2. Alcohol Inks

• Ideal for making fluid art, wispy effects, and petri dishes
  

• Creates beautiful transparencies and reactions
  

• Use sparingly—too much can soften resin or create bubbles
  

How to Use:
Add 1–2 drops per 30g of resin. Avoid alcohol inks that contain water, as it can interfere with curing.

3. Pigment Pastes

• Highly concentrated, offering deep, opaque colours
  

• Excellent for achieving solid colour effects and ocean-style pours
  

How to Use:
 Use a small amount (approximately 1–2% of the resin weight). Mix thoroughly to ensure even colour distribution.

4. Chalk Pastels (Scraped Powder)

• Budget-friendly and matte
  

• Good for beginners or rustic, stone-like finishes
  

Scrape with a blade, pre-mix into a small amount of resin, then add to your main batch.

What Not to Use in Resin

• Water-based colors (can cause bubbles or improper curing)
  

• Fresh food colouring
  

• Gel-based or moisture-heavy pigments
  

Always avoid anything with moisture—resin and water don’t mix well.

Best Practices for Pigment Use with Mycast Resin

• Mix pigments on wax paper or in a separate cup before adding to the resin
  

• Avoid adding more than 5–7% pigment by weight—it can interfere with the chemical reaction
  

• Stir gently to avoid trapping air
  

• If using multiple colours, let bubbles rise before pouring or use a heat gun after pour
  

Final Takeaway

Choosing the right pigment is just as important as choosing the right resin. Whether you’re going bold with mica or experimenting with alcohol inks, Mycast Epoxy Resin gives you the clarity, compatibility, and working time you need for artistic freedom—without compromising on finish or safety.
