I'm a little confused. On the forums I have read a number of times (at least I thought I did) that Elmers school glue cannot be removed from a fossil, once it has dried. But just for the sake of experimenting, I coated a small rock in elmers glue and let it dry. After it sat in the warm sun for awhile and was good and dried, I put it in water. And almost immediately, the glue softened up and turned white and sticky again. I let it soak for awhile and then washed it off. The Elmers glue washed right off.
Did I miss something? Or an I experimenting with the wrong kind of glue?
I know Elmers glue is not very recommended for coating fossils, but I just got curious and wanted to experiment. :-)
So if anybody can fill me in, that would be great!
