We all know that eggs are a staple in many households, but did you know that eggshells can be just as useful? In fact, there are at least 33 uses for eggshells that you may not have considered before. From gardening to cleaning, eggshells have a variety of practical applications that can make our lives easier.
Recycling your eggshells is not only eco-friendly, it’s also insanely beneficial for so many applications.
You can also utilize them to deter pests like slugs and snails, as the sharp edges of the crushed shells repel them. However, the uses for eggshells extend beyond that. They can be employed in the kitchen, for cleaning purposes, and even for beauty treatments.
When it comes to eggshells, there are a few basic things we need to know before we can start using them in various ways.
It doesn’t matter if you use white, green, or brown eggshells. Any eggshell will do for all of these applications
Here are some eggshell basics that will help us get started:
Eggshells are made up of calcium carbonate, which is the same material that makes up seashells, coral, and limestone.
This means that eggshells are a good source of calcium, which is an essential nutrient for our bodies.
Cleaning Eggshells For Use
Before using eggshells, it’s important to clean them thoroughly to remove any bacteria or germs that may be present.
To do this, we can rinse them with warm water and then boil them for 10 minutes.

To use eggshells, we need to crush them into small pieces.
This can be done by using a mortar and pestle, a rolling pin, or even a food processor.
I will add, I like to have a dedicated blender for my eggshells and blend them outside.
When you open the top, the fine dust goes everywhere. Make sure to wear a mask or move your face away from the blender when opening.
Eggshells should be stored in a dry place, away from moisture and humidity. We can store them in an airtight container or a plastic bag.
By keeping these eggshell basics in mind, we can start using eggshells in various ways and reap the benefits they have to offer.

Use Eggshells For Notes or Gifts
One of my fond memories as a child is my father leaving notes or money in eggshells.
He would make a hole in each end of the egg and blow the shell out. Then lightly rinse out the egg. Once dry, we would write a note and roll it up tight or a dollar bill, and place it inside the egg. He would then hide the egg for me to find.
Sometimes the eggshell note would say ‘time to go to bed’ or ‘I love you’. I always loved my little egg-surprises as a kid.
You can also use eggshells to create exquisite jewelry.
Here’s how to do it:
- Crush eggshells into small pieces.
