How to Make Crystal Egg Geodes

I love crystals and especially geodes, so how could I pass up the chance to turn some empty egg shells into crystal filled geodes. I saw it here at http://www.marthastewart.com/343344/crystal-egg-geodes.  Well, I couldn’t resist, so I started gathering supplies and ran into one problem.  Where to get Alum in bulk?  A 1 oz. jar for $4 is just too much for my budget.  I finally found a 1 pound bag at a place called Allyson’s Pantry (http://www.alisonspantry.com/ ) here in Utah ($6.00 for the bag). There are other places that have it on line.   I am excited to show you how to make Crystal Egg Geodes, so let’s get started.

Step 1:

Supplies:
1 empty (blown) egg shell
Pointed scissors
Glue
Paint brush
Alum (6+ Tbs. per color)
2 plastic or glass cups
Easter egg dyes (you choose what type, I paid $.99 for 6 pellets)
1 cup very hot water
2-3 cup size bowl
Spoon
Rubber type gloves (to keep your hands from being dyed)
Paper towels

Congratulations on taking First Place in the egg challenge. Very cool project that I will for sure try.

Thanks, it really surprised me. Lots of fun though.

you could also make a deep bowl and just poke the holes and put the alum into the holes to keep the egg whole because then you could crack the egg like a real geode, it'll look like a real egg and you can crack it to the candy inside

Try it and let me know how it goes.

Great instructable although your definition of super saturated is not quite correct. When a solution can hold no more medium at the current temperature then it has become fully saturated. A solution is super saturated when the solution is fully saturated at a higher temperature and then allowed to cool. This then allows the solution to hold more medium then if it had just been saturated. This is super saturated.

I stand corrected, Thank you for commenting and looking.

i found that alum crystals make a great antipersperant

[craftknowitall]

Yes it does! Thanks for looking.

These are so neat looking! This would be so fun to do with kids - though they might need to learn patience. :D

The patience results from making sugar crystals at a 1 week wait. Thanks for looking and commenting.
