How to Prevent Bubbles in Epoxy Resin Jewellery

← Back to how to make epoxy resin jewellery

Visible bubbles can detract from the beauty of handmade epoxy resin jewellery. With the right approach, you can achieve a flawless, glass-like finish, ensuring every piece looks professionally crafted.

Gentle Mixing and Gradual Pouring

The key to bubble-free resin starts with your mixing method. Stir resin and hardener together slowly, scraping the sides and base of your container. Vigorous mixing may blend in excess air that results in unsightly bubbles. Once mixed, pour the resin slowly into your mould from one side, letting the liquid flow naturally to fill intricate spaces.

Use a flat mixing stick to minimise air incorporation.
Allow the mixed resin to rest for a minute before pouring; this helps bubbles rise to the surface.

Using Heat to Remove Surface Bubbles

After pouring, surface bubbles are common but can easily be removed. Briefly pass a heat gun or a small gas torch at a low setting over the resin surface, holding it a few centimetres away. This encourages bubbles to rise and pop without forcing the resin to overheat. Avoid overheating or lingering in one spot, as this could lead to surface imperfections.

For smaller projects, a simple craft heat tool is usually sufficient.

Choosing the Right Resin for Fewer Bubbles

Selecting a resin designed for jewellery and small casts, such as the “Evershine Collection” Epoxy Resin Kit, can help achieve clearer results. Dedicated jewellery resins tend to have lower viscosity and are formulated to reduce bubble formation during mixing and curing. Always follow the manufacturer’s specific instructions for best results.

When This Matters Most

Bubble control is crucial when working with clear or lightly tinted resin, embedding flowers, or casting fine details where imperfections are easily seen. Consistency in your technique ensures each piece meets your creative vision.
