[Rockhounds] stabilizing thompsonite/chlorastrolite

[Tim Fisher]

I assume you are talking about massive thomsonite-Ca (no "p"), which 
like all zeolites contains water. Soak it to rehydrate it and keep it 
in a relatively humid environment. The specimens from MN are actually 
composed of one or more zeolite minerals and may or may not actually 
contain thomsonite and/or lintonite.
