Pyrite with salt expulsion
MEHo:
Thank you for the information! I don't think it will take long, before my specimen is broken. Because it has a big crack in the middle. To bad :'(. But anyway, it is very interesting!
(p.s Next time I inspect the mineral, I think I will wash my hands more proparly ;) )
Greetings, MeHo
MEHo:
I made some fotos of it. On these fotos you can't see the crack.
The front:
The back with the little with crystals:
srry, for the bad quality. My digital-camera isn't that great >:(
uwe p.:
...trying to remember what i should have learned at school...
the high sulphur part is not the problem, it´s the steam in the air which makes your pyrite getting crumbly - and i guess, the flavour is very bitter & aggressive (resulting from the H2SO3, i think...)
so, the sulphur and the steam cause a sulphurous acid (H2SO3, not H2SO4) precipitation which disbands yout pyrite.
putting the speciem into a glas//plastic box should help (well in this case everything seems to be lost anyway...) to keep the steam away and avoid the destrucion.
another way of conservation is to work with clear varnish, invisible and save.
should work,
have a nice day!

MEHo:
K, thank you for the information ;). I was planning to put it in a plastic box or something. But I don't have wone right now. It now is behind glass, but it still can come in touch with air.
I hope I get a box soon, so i can save it from complete deconstruction :P.
Greetings, MeHo
Galenit:
You cant this way.
Once the Prcoess has began, you nearly cant stop it. Nothin like closing it from fresh air, or anything else will help. There are only a few ppls who can stop it, and it take some month and is very expensive, so its just an option for really good and expensive Mineral specisms...
