Thoroughly Dry and Preserve the Fish First

Preserving a dead fish properly before embedding it in resin is crucial. The drying and preservation steps ensure the fish maintains its appearance and prevents future issues like decay or cloudiness in your resin artwork.

Why Thoroughly Drying Matters

Embedding organic materials such as fish requires them to be completely dry. Any retained moisture within the specimen can result in trapped air bubbles, cloudiness, or even decomposition inside the resin over time. Incomplete drying is the leading cause of embedded items deteriorating or discolouring within clear resin blocks.

Simple Steps to Dry and Preserve

Clean the specimen: Gently rinse the fish in water to remove all residues and pat it dry.
Desiccate fully: Use salt or silica gel to extract moisture over several days. Salt draws water from tissues; silica gel offers a reliable alternative for more delicate preservation.
Optional hardening: For firmer results, consider placing the fish in alcohol prior to drying, which can also help retain some colour and structure.
Patience is key: Allow ample time for the fish to dry completely before handling or embedding. Rushing this step may cause complications during the resin pour.

Choosing the Right Resin for Embedding

The thickness and size of your project will guide your resin choice. For fish larger than 5 cm thick, Epoxytable 10-Ten is ideal for deep pours without overheating. If your casting is up to 5 cm, a resin like EpoxyTable 5-Five balances clarity and ease of use. Smaller objects can be embedded with multipurpose resins such as “Trasparente” for up to 2 cm thickness.

When This Matters Most

This careful preparation is particularly important for memorial pieces, display blocks, or scientific specimens, where the preservation and appearance of the embedded fish are key to the end result.
