So the material they line the safes with is lime, rather than gypsum?

I'm sure hoping not. Gypsum CaSO4·2H2O Lime CaO

I'll bet you know I was shorthanding for hydrated lime, or calcium
hydroxide, Ca(OH2). g

I'll bet you mean Ca(OH)2. g

Hydrated lime is what plaster walls were once made of (as in the walls in my

Hydrated lime is *part of* what plaster walls *are still* made of, among other
constituents including sand, portland cement, perlite or vermiculite, and (in
bygone days) often horsehair.
