Small air bubbles trapped in epoxy resin can spoil the look of your final creation. Whether you’re making jewellery, coasters, or keepsakes, learning to reduce and remove bubbles ensures a smooth, professional result.
Tips for Minimising Bubbles During Pouring
Start by mixing your resin components gently in a flexible container, like the Flexible Silicone Cup for Mixing and Pouring Resin. Pour the mixed epoxy slowly and in a thin stream into your mould, allowing bubbles to rise naturally and reducing the chance of trapping air. Using a well-designed mould, such as the Silicone Circle Mould, also assists because its flexibility makes it easier for trapped bubbles to escape.
Removing Bubbles After Pouring
Once the resin is in the mould, address any bubbles that appear on the surface. Gently pass a heat gun set to its lowest temperature or a hairdryer over the resin surface; the warmth helps the bubbles pop and disappear. Alternatively, use a toothpick or pin to individually burst surface bubbles. Work slowly and avoid direct, prolonged heat as excessive warmth can affect the curing process.
When Bubble Removal Matters Most
Bubble removal is especially important for pieces where clarity and detail matter, like resin jewellery, art pieces, or when encasing keepsakes. Even small imperfections in clear resin can distract from delicate designs or the preserved items within.
