How Do I Avoid Bubbles When Mixing Epoxy Resin for Jewellery?

Bubbles are a common frustration for anyone mixing epoxy resin for jewellery. Achieving flawless, glass-like pieces starts with understanding how to minimise air entrapment during the preparation stage.

Mastering the Mixing Technique

To minimise bubbles, pour the resin and hardener into your mixing cup and combine them slowly and steadily. Stir gently, with consistent motion, taking care not to whip or fold air into the mixture. Regularly scrape the sides and bottom of your container with your mixing tool to ensure an even blend without trapping excess air. Patience is key here—rushing the process increases the likelihood of bubbles forming within your finished piece.

Letting Air Escape Before Pouring

After mixing, allow your resin to rest for a few minutes before pouring. This pause gives lighter bubbles time to rise to the surface naturally. If you notice small bubbles persisting, you can lightly exhale over the surface or gently warm the resin with a heat source from a safe distance to help them burst without disturbing the mix. Pour slowly into your moulds for even fewer inclusions.

Choosing Bubble-Reducing Products

Not all resins behave in the same way. Kits designed for jewellery—such as the Evershine Collection—feature enhanced degassing characteristics, making it easier to achieve clear, detailed results even when embedding delicate items like dried flowers. Beginners often find kits with reliable 1:1 mixing ratios helpful for reducing mistakes that can lead to unwanted bubbles.

When This Matters Most

Clear castings for pendants, earrings, and pieces with embedded elements show bubbles most clearly. Take extra care with your mixing and pouring routine when working on showcase items or gifts where a transparent, professional look is important.
