After hearing from my mother when she was a kid, they used to preserve eggs in "waterglass" I did a Google about the stuff. Seems like it's a handy thing to have around. http://en.wikipedia.org/wiki/Sodium_silicate Has anybody tried it, or have it in their stash? I like the idea of the gun safe protection..and may try a few batches of saw dust/waterglass mix to see how it works, and then modify one of my cheaper gun safes with a load of it.
