Embedding coins in epoxy resin can create striking jewellery, coasters or keepsakes, but achieving a flawless result means taking care to prevent bubbles and protect your coins from tarnish. A few simple preparation steps make all the difference.
Preparing Coins for Resin Projects
Start by thoroughly cleaning your coins with mild soap and water, removing any dirt or grease. Dry them well with a soft cloth, as even small traces of moisture can cause unwanted reactions or tarnishing beneath the resin. For an extra layer of shine and protection, you may wish to gently polish the coins and consider sealing them with a clear lacquer that is compatible with craft projects. This can help guard against future discolouration after embedding.
Minimising Bubbles in Epoxy Resin
Resin bubbles can spoil the look of your finished piece. One of the most effective ways to avoid them is to pour your resin slowly, ensuring that air has time to escape naturally. Pre-warming the resin gently (by placing sealed bottles in warm water) before mixing can also help reduce viscosity and release trapped air. After pouring, use a heat gun or craft torch in quick, sweeping motions across the resin surface to pop any visible bubbles. Try not to disturb the coins once the resin starts curing.
Choosing the Right Resin and Tools
Selecting a medium-viscosity, crystal-clear epoxy such as One-2-One resin can enhance clarity and make bubble removal more manageable. Use high-quality silicone moulds to shape your creations. These moulds release easily and help avoid surface flaws, making them ideal for coasters or coin displays.
When This Matters
Taking care with bubbles and tarnish is essential whenever clarity, detail and lasting finish are priorities—whether crafting commemorative jewellery or decorative home accents. These steps ensure your embedded coins remain the centrepiece of your resin art for years to come.
