How to Minimise Bubbles When Making Epoxy Resin Pendants

Q: Techniques to Reduce Bubbles

Mix Slowly: Stir your resin and hardener together gently but thoroughly, moving the mixing stick in a smooth, slow-motion to avoid drawing in excess air. Let Resin Stand: After mixing, let the resin rest for a minute to allow trapped bubbles to rise naturally to the surface. Release Surface Bubbles: Pop any surface bubbles with a toothpick or use gentle heat (such as a heat gun or a lighter waved briefly about 10 cm above the surface) to encourage bubbles to burst before curing. You can also opt for products designed with enhanced degassing properties, such as the Evershine Collection Jewellery Epoxy Resin Kit , which is formulated to help bubbles dissipate more easily.

How Do I Minimise Bubbles When Making Pendants?

Getting a flawless, glass-like finish for your resin pendants often comes down to minimising air bubbles during the making process. With the right methods and materials, you can achieve consistently clear, beautiful results.

Why Do Bubbles Form in Epoxy Resin?

Bubbles in epoxy resin are typically caused by mixing too quickly or incorporating air while stirring. Even room temperature and humidity can play a role, as cool or damp conditions may trap bubbles more easily. Being aware of these factors helps you adjust your technique for clearer pendants.

When Minimising Bubbles Matters Most

If you’re making pendants with delicate details, clear backgrounds, or embedding small items like dried flowers, any trapped air can distract from the design or create unwanted texture. Investing extra care in bubble prevention is especially worthwhile for projects aiming for maximum transparency or including intricate inclusions.
