Getting the thickness right is crucial when embedding insects in resin. Every resin has its own safe pour limit, and choosing accordingly helps achieve both clarity and safety.
Recommended Maximum Pour Thickness by Resin Type
Most clear epoxy resins used for embedding are designed for pours of up to 1.5–2 cm per layer. For example, “Icrystal” is suitable for up to 1.5 cm, while “Trasparente” supports layers up to 2 cm. If your project needs more depth—say for larger displays or blocks—resins like “EpoxyTable 5-Five” can be poured safely up to 5 cm per layer, while maintaining clarity and preventing overheating.
How to Pour Resin for Embedding Insects
For small projects, pouring one single layer within your resin’s recommended limit usually delivers the best finish and minimises bubbles. If your design requires greater thickness, pour the resin in several layers—letting each fully cure before adding the next. This process helps avoid cloudiness, excessive heat, and warping, which can damage delicate specimens.
- Choose a resin formulated for casting, not coating
- Prepare insects by drying them thoroughly
- Pour gradually and remove surface bubbles between layers
When Layer Thickness Matters Most
Staying within a resin’s safe thickness limit is especially important for preserving fragile insects. Exceeding the guidance can increase heat during curing, risking deformation or discolouration. Always check your chosen product’s technical sheet before starting a new design.
