Thank you. The Elmer's glue you had, was it washable kind? I did find some nonwashable Elmer's glue online. Can you post a picture of your son's egg when done? I would love to see it.I painted eggshell with the washable glue and covered with alum powder and let dry over night. I left eggshell in alum solution since Thursday in hopes that the crystals would form . . . still no luck.Maybe my soution not saturated enough, maybe it was yhe washable glue. I will try again.
Thank you for your reply. I will try again with non-washable white glue. Good thing I was able to wash off the washable glue and alum powder from goose eggshells that I bought online. Will try again today. The kids and I cannot wait! This is a wonderful project, thanks for posting this. If I can actually make these crystal egg geodes . . . I will do this project with my Girl Scout troop. I am keeping my fingers crossed. Thanks, again.
I only had Elmer's washable glue to use for alum powder to adhere to eggshell. I checked around 12 hour mark and they will know crystals. Not even tiny ones. Is this because of the washable glue that was used? Did blue and alum powder get washed away after soaking in the solution? Can I use Gorilla Glue?
Sorry, for typo. At 12 hour mark, I did not see any crystals. Not even tiny ones.
