Is borax and alum the same thing?
Borax (Sodium tetraborate) is used as a cleaner in many parts of the world and may be purchasable in supermarkets or home handyman stores. Boric acid on the other hand is used as a toxic pesticide. (Sodium tetraborate is a salt of Boric acid). Alum is Aluminium Sulfate.
Can you make your own geodes?
Natural geodes are hollow rock formations that contain deposits of crystals. Assuming you don’t have a geological timeframe to obtain a geode and don’t want to buy a geode kit, it’s easy to make your own crystal geode using alum, food coloring, and either plaster of Paris or an eggshell.
How do you make borax crystals in eggshells?
Brush some glue on the inside the eggshell, and then sprinkle borax inside the shell. Pour out any excess borax. Next, wait for the glue to dry. The borax coating inside the egg will act as starting “seeds” for crystallizing the borax solution.
How do you make alum?
Pour 1/2 cup of hot tap water into a clean jar. Slowly stir in alum, a little at a time, until it stops dissolving. Don’t add the whole amount; just enough to saturate the water. Loosely cover the jar with a coffee filter or paper towel (to keep dust out) and allow the jar to sit undisturbed overnight.

What can I use to grow crystals in an egg?
While the glue is still wet, sprinkle some alum powder onto the glue. The powdered alum will serve as a starting point for a crystal to grow. If you want smaller crystals, completely coat the inside of the egg with alum because the crystals will not be able to grow very large when they are close together.
