Is it safe to put glitter in resin?
Types of Glitter and Compatibility
Most craft glitters are made from plastic (polyester) or metalized film. Plastic glitters are usually safe and won't affect curing. Metalized glitters can sometimes cause discoloration or interfere with curing if the metal reacts with the resin, but this is rare.
Biodegradable glitters (often made from cellulose) may not hold up well in resin and can break down or lose their sparkle. Always test a small batch if you're unsure. Fine glitter (often called 'fairy dust' or 'extra fine') disperses best and won't sink as quickly.
- Plastic glitter: generally safe
- Metalized glitter: may react, test first
- Biodegradable glitter: may not last
- Fine glitter disperses more evenly
How to Use Glitter in Resin
Add glitter to your resin after mixing parts A and B, but before pouring. Stir gently to avoid creating bubbles. A little goes a long way—start with a pinch and add more if needed. Too much glitter can make the resin thick and affect curing.
For a suspended look, use a resin with a longer working time and stir slowly. Glitter may settle over time, so for even distribution, pour in layers or use a glitter that's coated to prevent settling. Always wear gloves and work in a ventilated area.

- Pour in layers for even distribution
Common mistakes
- Using too much glitter, which can prevent the resin from curing properly or make it lumpy.
- Assuming all glitter is resin-safe—some metallic or biodegradable types may cause issues.
- Not testing a small batch first, leading to wasted resin if the glitter reacts poorly.
