Resin casting lets you create beautiful displays by embedding objects, but when it comes to fish, extra care is essential. It’s not as simple as popping any specimen into resin—here’s why.
Preservation Is Essential
You cannot embed just any fish in resin without careful preparation. Fish must be thoroughly preserved and completely dried before casting. Any retained moisture will cause issues such as odour, bubbling, or even decay inside the cured resin, spoiling both appearance and safety. Standard preservation methods often involve drying or chemical treatments to eliminate natural moisture and prevent decomposition.
Choosing the Right Resin
The thickness of your cast will influence which resin is suitable. For casts up to 2 cm thick, consider a clear epoxy like “Trasparente” – Multipurpose Clear Epoxy Resin for Casting. Larger specimens may require deep pour products such as “Epoxytable 5-Five” for up to 5 cm, or “Epoxytable 10-Ten” for up to 10 cm. Well-chosen resin minimises risks of excessive heat, bubble formation, or incomplete curing, which is vital for successful embedding of preserved organic matter.
When This Matters
Preservation is especially important if you want to keep your cast odour-free and maintain a clear, attractive appearance. Damp or poorly preserved specimens often result in unsightly bubbles or milky resin patches, ruining the display. Only properly prepared fish will achieve the durable, crystal-clear look most makers desire.
