How to create an embedded specimen


Creating an embedded specimen involves preserving an object or organism within a clear material, usually resin, to create a visually appealing and educational display. Here's a guide on how to create an embedded specimen:


1. Specimen: This could be an insect, flower, seashell, small toy, or any object you want to embed.

2. Clear Casting Resin: Available at craft stores, this will serve as the embedding material.

3. Resin Catalyst or Hardener: Follow the instructions on your specific resin for mixing ratios.

4. Resin Mold: Choose a mold that suits the size and shape of your specimen.

5. Release Agent (optional): To help release the specimen from the mold.

6. Mixing Cups and Stirring Sticks: Disposable cups and sticks for mixing resin.

7. Safety Gear: Gloves and safety glasses to protect your skin and eyes.

8. Labels or Markers: For labeling and dating your specimen.


1. Select and Prepare the Specimen:

  - Choose a specimen that fits the size of your mold.

  - Clean and dry the specimen thoroughly. If it's organic, consider drying it completely.

2. Prepare the Mold:

  - Ensure the mold is clean and dry.

  - Apply a release agent if recommended for your specific resin and mold.

3. Mix the Resin:

  - Follow the instructions on your resin kit for mixing ratios.

  - Wear safety gear while handling resin.

  - Use disposable cups and stirring sticks for mixing.

4. Pour a Thin Layer:

  - Pour a thin layer of resin into the mold, enough to cover the bottom.

  - Allow it to partially cure. This helps prevent the specimen from floating to the surface.

5. Place the Specimen:

  - Gently place the specimen onto the partially cured resin layer.

  - Adjust the position as needed.

6. Pour the Remaining Resin:

  - Pour the remaining resin into the mold, covering the specimen completely.

  - Make sure the specimen is centered and submerged.

7. Remove Air Bubbles:

  - Use a heat gun or a torch to carefully remove any air bubbles that may have formed in the resin.

8. Allow Curing:

  - Allow the resin to cure according to the manufacturer's instructions. This typically takes several hours to a day.

9. Demold the Specimen:

  - Once fully cured, carefully demold your embedded specimen. Follow the instructions for releasing the specimen from the mold.

10. Label and Display:

  - Label your embedded specimen with relevant information such as the specimen type and date.

  - Display your embedded specimen in a location where it can be observed and appreciated.


- Work in a well-ventilated area when dealing with resin.

- Follow all safety guidelines provided by the resin manufacturer.

- Experiment with different types of molds and arrangements to create unique displays.

Creating embedded specimens can be a fascinating way to preserve and showcase objects or organisms, making them ideal for educational purposes, art projects, or personal collections.
