Remove Trapped Air Bubbles Immediately After Pouring

← Back to How to put insects in resin?

Clear resin casting often results in air bubbles being trapped around your objects, especially with delicate items like insects. Removing these bubbles promptly after pouring is crucial for a flawless, glass-like effect.

Why Bubbles Happen and Why They Matter

Mixing and pouring epoxy resin naturally introduces air, especially when embedding organic materials. If not removed, bubbles can distort your cast, obscure embedded items, or even damage the look of your finished piece. Taking action straight after pouring ensures preserved clarity and professional results.

Best Techniques to Remove Air Bubbles After Pouring

• Surface Sweeping: After pouring, gently exhale over the resin surface or wave a heat gun/hair dryer set to low over the project. The warmth helps bubbles rise and pop without overheating the resin. Always keep the airflow moving and avoid holding heat too close.
• Toothpick or Stick: For stubborn bubbles trapped near delicate items like insects, use a cocktail stick to carefully nudge them up.
• Rest Time: Letting the resin rest for a minute or two after pouring often brings many bubbles to the surface naturally, making them easier to remove.

Choosing a low-viscosity resin, such as “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm, can reduce the likelihood of air being trapped.

When Quick Bubble Removal Matters Most

Immediate attention is vital when embedding insects or other collectibles. These objects are sensitive to surface marks and can trap small pockets of air. Acting quickly after your pour ensures your piece stays clear and visually striking, especially in intricate or shallow castings.
