How Do I Prevent Bubbles in Resin Spheres?

← Back to How do you make a sphere mould with resin?

Struggling with trapped air bubbles when making resin spheres? Achieving a clear, bubble-free finish takes a bit of know-how and patience. Here’s how you can minimise bubbles for beautifully smooth resin spheres.

Mixing and Pouring Techniques

Bubbles often occur during mixing or pouring. To limit them, gently combine your resin and hardener, stirring slowly rather than whipping. When ready, pour the resin in a thin, steady stream, which helps push less air into the mould and encourages bubbles to rise to the surface before curing begins.

Handling Bubbles in the Mould

Once the resin is in your sphere mould, use a cocktail stick or toothpick to nudge any visible bubbles, especially around the edges or corners. Giving the filled mould a few gentle taps can also release air pockets clinging to the surface. Tools like the “3 Sphere” – Silicone Mould for Jewellery and Crafts are easy to use and designed to reduce trapping of air due to their polished interior.

When This Matters

Perfecting your bubble-removal technique is especially important for clear or decorative resin spheres meant for jewellery or display. Bubble-free results showcase embedded materials and lead to a professional finish.
