How to Prevent Bubbles in Resin Pendants

Q: Best methods to minimise bubbles

Mix slowly and thoroughly: Use a gentle, steady hand when combining resin and hardener. Aim for a deliberate, scraping motion rather than quick whisking. Pour with care: Guide the resin slowly into your mould or bezel, letting it flow from the side to avoid trapping extra air. Bubble removal: Once poured, lightly pass a heat gun or torch over the surface. The warmth will help any remaining bubbles rise and pop before curing starts. Choose low-bubble resin formulations: Some resins are designed to help bubbles dissipate. For example, the Evershine Collection Epoxy Resin Kit offers enhanced degassing properties ideal for jewellery making.

How do I prevent bubbles in resin pendants?

A flawless resin pendant can be ruined by trapped air bubbles, but with the right preparation and techniques, you can achieve that crystal-clear look so many resin crafters crave.

Why bubbles form in resin pendants

Air bubbles are a frequent challenge in resin work, typically introduced during mixing or pouring. Fast, vigorous stirring causes more air to become trapped in the resin, while aggressive pouring increases the risk of bubbles getting stuck on inclusions or mould surfaces. Even tiny traces of moisture or dust can contribute to unwanted bubbles in your finished pendant.

When this matters

Eliminating bubbles is especially important for pendants containing clear backgrounds, embedded objects, or delicate details. Any visible air pockets may distract from dried flowers, glitters, or pigments, reducing the impact of your design. Investing extra care and the right materials can dramatically improve your results.
