I love collecting minerals, especially geodes. There is something so magical about minerals and gemstones. To me, they are like a piece of heaven that fell from the sky.
But as much as I love collecting geodes, they can get pretty expensive so I I thought it would be great if we could DIY our own! I was inspired by Geode Eggs that I saw from Martha Stewart. Instead of using fragile and tiny egg shells, I wanted to make our own base for these sparkly geodes with polymer clay as a base!
It’s a pretty easy DIY that only involves a few ingredients and a few steps, and the result is so pretty!
-Glue and foam brush
1. Take out one block of polymer clay and knead it until it softens. If you want to get a marble look, you can mix two colors of clay together. Once the clay is nice and malleable, use your thumb and palm to press the ball of clay down until you get a flat disk. With your thumb and forefinger, pinch around the edges until you create a bowl-like shape.
2. After forming your bowl, bake the clay by following the instructions on the packet. Make sure to let the clay fully cool down before moving onto the next step.
3. Completely cover the inside of the bowl in glue. You can do this by pouring in a generous amount of glue into the bowl and using the foam brush to spread it around evenly.
4. While the glue is still wet, coat the inside in alum powder.
5. Mix together 1/2 cup of alum powder and one cup of hot water, making sure that the powder completely dissolves in the water. Then add in about 10-20 drops of food coloring.
6. Once the glue and the alum powder has set, put the bowl into the mixture. Let it sit overnight, then check in the morning how your geodes have crystalized!
Carefully take them out of the solution and let them airdrop for at least 24 hrs. You can reuse solution by heating it up in the microwave and restating to dissolve the alum. Add more alum as needed to the solution.
