Preserving sand dollars involves cleaning, drying, and sometimes hardening them to maintain their delicate structure. According to the video "Sand Dollars Collecting & Preservation Tips", there is a "quick and easy way to find. And preserve sand dollars" discussed in the resource, suggesting accessible methods exist for this purpose.
Here are the common steps typically followed to preserve sand dollars found on the beach:
1. Cleaning the Sand Dollar
The first step is to clean the sand dollar to remove any remaining organic material. If the sand dollar is still alive (gray or brown and covered in spines), it should be returned to the ocean. Only preserve white sand dollars that are already deceased.
- Rinse: Gently rinse the sand dollar under cool, running water to remove sand and debris.
- Remove Tissue: If any dark, fuzzy material (tissue) remains, it needs to be carefully removed. You can use a soft brush (like a toothbrush) or soak the sand dollar in fresh water for a day or two, changing the water periodically, which helps loosen the tissue.
2. Bleaching for Whiteness
To achieve the classic white appearance and further sanitize the sand dollar, a bleach solution is commonly used.
- Prepare Solution: Mix a solution of half water and half household bleach.
- Soak: Submerge the cleaned sand dollar in the bleach solution for a few minutes. Do not over-soak, as this can make the sand dollar brittle. Just soak long enough for it to turn white.
- Rinse Thoroughly: After bleaching, rinse the sand dollar completely under running water to remove all traces of bleach. This step is crucial to prevent future deterioration.
3. Drying
Proper drying is essential to prevent mold and strengthen the sand dollar.
- Placement: Place the sand dollar on a paper towel or absorbent cloth in a warm, dry location away from direct sunlight.
- Position: Ensure it is positioned so air can circulate around it. Some people prop it up slightly.
- Time: Allow it to dry completely, which may take one to two days, depending on humidity. It will feel light and sturdy when fully dry.
4. Hardening (Optional)
For added durability, especially if the sand dollar will be handled frequently or used in crafts, you can harden it.
- Prepare Solution: Use a mixture of white glue and water (about 1 part glue to 1 part water) or a clear acrylic spray sealant.
- Apply: If using the glue solution, you can gently dip the sand dollar or carefully brush the solution onto both sides. If using spray sealant, apply a light, even coat according to product instructions.
- Dry Again: Let the sand dollar dry completely after applying the hardening agent.
By following these steps, you can preserve the delicate beauty of sand dollars for display or use in various projects. Remember, handle them gently even after preservation, as they remain fragile.
