Ostara Craft: Easy, Cheap Egg Geodes for the Altar
I love crafts to decorate my altar for Wiccan holidays. The springtime is especially fun for crafting—maybe it’s all the bright and cheerful colors. One science project I worked on with my kids turned out to be the perfect Ostara craft—crystallized “geodes” made out of simple household supplies. It’s really fun to watch them take form, and once finished they look great as a decoration.
You don’t need anything expensive or special for this Ostara craft—you probably have most ingredients in the house already. If you are raising Pagan kids, they’ll probably love this craft. Give it a go!
Ostara Craft: Egg Geodes
Tell Us About It:
Have you ever made egg geodes?
What You Need
Eggshell pieces (great way to recycle)
PVA Glue (Elmers or something like it is fine)
A cheap child’s paintbrush
Something to crystalize— salt, baking soda, alum, sugar, Epsom salts, etc.
Ostara Craft Step One: Start With Shells
Plan to have an egg dinner or breakfast. When you break the eggs, try to keep large pieces of shell somewhat intact. Set them aside in a big bowl.
Pour some warm tap water into the bowl and a squirt of dish washing soap. Carefully swish around the eggshells without breaking them up. Wash off the egg gook and put the clean shells on a dish with paper towels to let them dry.
Trim off any tiny shell bits or hanging pieces of shells with a pair of scissors.

Ostara Craft Step 2:
I am using kosher salt this time as my crystalizing agent, but I’ve tried other things. Different crystalizing agents seem to have unique results, so it can be fun to experiment.
This part is not necessary but can help get the crystallization process started so the crystals stick where you want:
Brush some PVA glue around the inside of the eggshell and along the broken edges.
Sprinkle over the wet glue with your crystalizing agent, whatever you have chosen, then dump out excess.
Set the eggshells aside for a few hours so the glue fully dries.
I sort my eggshells into different bowls because I like to make all different colors. I put them all on a tray for easy transport.

Ostara Craft Step 3: Melting the Crystals
Put some water in a pot and add the crystallizing agent. The formula is about 2.5 cups of water to 1 cup of crystallizing agent, though this can vary. You want to bring it to a boil so the crystallizing agent fully melts into the water.
If it melts quickly and disappears, add a little more crystallizing agent in increments until it stops melting—that means your water can’t hold anymore.
If it won’t all melt and the water is boiling away furiously, there is too much crystallizing agent. Add a little more water and bring it to a boil.
Making Crystal Eggs
If after a day or so the crystals seem to be forming on the sides of the bowl instead of the egg shells, take the shells out and set them aside on a dish. Scrape down the salt and put the salt and water back into a pot (doing one color at a time—don’t mix the colors or they’ll all come out brown).
Bring the water back to a boil—add a little more if need be to get the crystalizing agent re-melted.
Put the eggshells back into the bowl and pour the colored water with the crystalizing agent over it again. And wait some more.
Ostara Craft Step 4:
Pour the water impregnated with your melted crystalizing agents into the eggshells in the bowls. You don’t need a lot—maybe ¼ cup per bowl. The shells do not need to be submerged.
Dribble in a few drops of food coloring or egg dyes if you wish. I put different colors in each bowl. Swish just a little to distribute the color.
Now here comes the hard part—wait! You can wait overnight, or wait a week—it’s up to you. The longer you wait, the more water that evaporates from the bowl, the more crystals will develop on your eggs.
You can help along the evaporation by sticking the tray in an oven set to low for a while or putting it out under the sun or in a sunny window.
When you like the look of them, or when the water is all evaporated, let the eggshells dry and have fun decorating with them.
Egg Geodes In the Making

Setting Up the Ostara Altar
I like to decorate my altar by putting the geodes into a little cauldron. They also look pretty scattered around the altar.
Give them extra shine and help keep the crystals intact by spraying them with a clear sealer.
One year I’m going to try hot gluing them onto a spring wreath for the front door, but I’ve yet to get to that project. If you do it, maybe you can send me a picture.
