How do I avoid bubbles in resin jewellery?

← Back to How to create resin pendants?

Bubbles are a common challenge when crafting resin jewellery, but with a few careful techniques, you can achieve crystal-clear results. Here’s how to keep your resin pendants free from trapped air and imperfections.

Mixing Resin Slowly and Thoroughly

The most effective way to prevent bubbles is to mix your resin and hardener together slowly and steadily. Fast or vigorous stirring introduces air, which often gets trapped in the mixture. Use a gentle hand, stir in one direction, and scrape the sides and bottom of your mixing cup to ensure full blending without excess air. This is easy to do with beginner-friendly resin systems such as the “Evershine Collection” kit, which uses an uncomplicated 1:1 mixing ratio—making careful mixing even simpler for newcomers.

Choosing and Preparing Inclusions

When adding decorative items, such as flowers or glitter, always ensure they are completely dry before embedding them in resin. Any moisture in inclusions can create bubbles or cloudiness during curing. Gently pressing lightweight items into a thin layer of poured resin before covering with more resin can also help limit trapped air pockets.

Finishing Touches: Releasing Trapped Air

Once your resin is mixed and poured, allow it to settle for a few minutes. Next, gently pass a low-heat source—such as a craft heat gun or even a warm breath from a straw—just above the resin’s surface. This helps bubbles rise and pop before the curing process begins, giving you that flawless, glass-like finish resin jewellery is known for.

When Bubble Prevention Matters Most

Bubble prevention is especially vital for pendants and small pieces where clarity is essential for showcasing colours or embedded designs. High-quality resins designed for jewellery, like the “One-2-One” and “Trasparente” ranges, can also help minimise trapped air due to their clarity and self-levelling properties.
