Preservation Methods
There are several methods to preserve sand dollars, each with its own advantages and disadvantages. Let’s explore some of the most popular techniques:
1. Salt Preservation
One of the most common methods of preserving sand dollars is using salt. Here’s how to do it:
-
Thoroughly clean the sand dollar using a soft brush and warm water.
-
Place the sand dollar in a container filled with a mixture of salt and water. The ratio should be about 1 part salt to 3 parts water.
-
Cover the container and let it sit for several weeks. The sand dollar will gradually dry out and harden.
-
Once the sand dollar is dry, remove it from the saltwater solution and brush off any remaining salt crystals.
-
Store the sand dollar in a dry, cool place to prevent any damage or discoloration.
2. Epoxy Resin
Epoxy resin is another effective method for preserving sand dollars. Here’s how to use it:
-
Prepare the sand dollar by cleaning it thoroughly with warm water and a soft brush.
-
Apply a thin layer of epoxy resin to the back of the sand dollar, ensuring that it covers the entire surface.
-
Place the sand dollar on a flat surface and let the resin cure for 24 hours.
-
Once the resin is cured, you can display the sand dollar as a beautiful piece of art.
3. Drying in a Desiccator
Drying sand dollars in a desiccator is a gentle method that preserves their natural beauty. Here’s how to do it:
-
Thoroughly clean the sand dollar with warm water and a soft brush.
-
Place the sand dollar in a desiccator filled with silica gel packets.
-
Close the desiccator and let it sit for several weeks. The silica gel will absorb the moisture, causing the sand dollar to dry out.

Once the sand dollar is dry, remove it from the desiccator and brush off any remaining dust or particles.
