What Makes This Work
When a saturated solution cools, the dissolved substances can no longer stay in that state, leading to crystallization. In this case, the borax solution creates beautiful, sparkling crystals as it cools and evaporates.

Materials
To start this project, gather the following materials: You may also find How To Make Baking Soda Crystal Heart Growth useful.
- Red eggshells (cleaned and dried)
- Borax powder
- Water
- A heat source (like a kettle or pot)
- A small container for mixing
- A spoon for stirring
It’s critical to handle borax carefully, so an adult should supervise the process involving hot water. You may also find Crystal Geode Eggs Grow Into Calm useful.
Steps
Prepare the Eggshells: Ensure the red eggshells are clean. Rinse them thoroughly and let them dry completely. You can customize your shells with different colors to add more vibrancy to the final display.
Make the Borax Solution: Boil water and mix in the borax powder. The ratio is typically about three tablespoons of borax for every cup of water. Stir it until fully dissolved. If you are looking for the perfect balance, make sure no grains remain in the solution.
Fill Your Eggshells: Pour the prepared solution into the red eggshells. Ensure not to overfill them; leave a bit of space for evaporation.
Let the Crystals Form: Place the filled shells somewhere stable and undisturbed. Over the next few hours to days, watch as the crystals gradually grow. Look for changes in the crystal structure as they begin to form.
Remove the Crystals: After a day or two, you’ll notice the crystals forming in the eggshells. Carefully remove the shells from the solution and let them dry. That drying time allows the crystals to harden properly and gives them a beautiful shine.
Clean Up: Dispose of any remaining solution and wash your tools. Rinse your hands thoroughly after handling borax.
What Goes Wrong and How to Fix It
Sometimes, the crystals might not form as expected. If they come out dull or too small, it could be due to an insufficient concentration of borax. Ensure you use a strong solution. If you notice the crystals clumping together, it often indicates too much borax in the mix. Adjust the solution for next time.
Where to Display It
These beautiful crystal geodes look stunning in various places. You can place them on windowsills, shelves, or even as part of a centerpiece. The sunlight will catch the crystals and create lovely reflections throughout your space.

Variations
For added creativity, consider using different colored borax or mixed materials. You can try using different egg shapes or even combining these geodes with other crafts. For instance, check out this guide on how to create crystal treasures for a different project.
FAQs
How long does it take to grow the crystals?
The initial crystal growth usually takes 1-2 days, but you can leave them for longer to achieve bigger crystals.
Can I use other materials for this?
Yes, while borax is commonly used, you can experiment with other solubilized crystals like sugar or salt to see what forms.
My crystals didn’t turn out well. What happened?
There could be several reasons, such as impurities in the water or borax solution’s concentration. Start with a fresh batch and ensure everything is clean before you begin.
How should I care for my crystals?
Keeping them in a dry place will maintain their beauty. Avoid touching them too often to ensure they don’t lose their sparkle.
Are there any safety precautions I should take?
Yes, exercise caution when handling hot water and borax. Always have an adult supervise the process.
Can kids help with this project?
Absolutely, but ensure they have adult supervision, especially when it comes to handling hot liquids and chemicals.
