Choosing the Right Resin for Clear Insect Embedding

Clarity and appropriate pour thickness are crucial for success when embedding insects in resin. “Icrystal” – Clear Epoxy Resin – Odourless Formula – Up to 1.5cm is perfect for jewellery or small objects. For deeper, bubble-free castings, “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm and “EpoxyTable 5-Five” – Deep Pour Epoxy Resin offer the clarity and working time needed for larger displays or thicker pours.

Step 1: Prepare and Seal the Insect Specimen

Begin by choosing only dried, preserved insects. Place the specimen on absorbent paper in a dry location for at least several days to make sure all moisture is removed, as trapped water can cause cloudiness or decay inside the resin. Handle delicate insects with fine tweezers or an artist’s brush to avoid damage.

To prevent future colour loss or resin bubbles, seal the specimen with a thin coat of clear, fast-drying spray lacquer or brush-on sealant. Let it dry fully before continuing. This helps stop air or natural oils from leaking into the resin, ensuring clarity and preserving detail.

Step 3: Mix the Resin Correctly

Select the resin most suitable for your project’s thickness. For example, use “Icrystal” for projects up to 1.5 cm or “Trasparente” for up to 2 cm per layer. For larger castings, choose “EpoxyTable 5-Five” (up to 5 cm) or “Epoxytable 10-Ten” (up to 10 cm). Check the instructions for the correct mix ratio and working time for your chosen resin.

Mix resin components precisely, blending slowly to reduce air bubbles. Once mixed, let the resin sit for a few minutes—this allows bubbles to rise for easier removal. Quickly move on to the embedding stage before the resin begins to set.

Step 5: Demould and Finish the Piece

Once fully cured (refer to your resin’s instructions for curing time), gently pop your creation from the mould. Trim away any rough edges, and, if needed, sand the surface with fine-grit paper followed by polishing paste for a glossy, professional finish. Take care not to overheat the surface during sanding, and always work gently around the embedded insect.

Resin Curing: Ensuring Clarity and Bubble-Free Results

Temperature and environment play a key role in the curing process. Work at room temperature, protect your project from dust, and avoid moving the mould during cure. Rushing the pouring process or introducing moisture are common causes of bubbles. Most clarity issues are resolved by taking your time during mixing and pouring, and by choosing a resin like “Trasparente” Epoxy Resin that is formulated for high transparency.
