Recently I got some crystal and mineral bits that were clearly stored outside, and some are in pretty bad shape. Almost all of them are NOIDS, AND I'm driving myself to drooling brain death trying to look them up. Once I have the really dirty, fragile ones identified, I'll explore methods of cleaning them.
Anyways, folks around have asked for photos, so here we go. Buckle up, there's a lot of rocks.
I'll resize when everything is done being posted.
I am pretty sure these are all the same.
Same rock, back side.
Needs cleaning. You are going to see a LOT of dirty specimens, a real crying shame.
Stalactite, I think. I forgot to get a photo of the inside, the crystals are a crust over some kind of fibrous, pithy material.
First of several that I want to clean, but are too furry for manual dirt removal.
Some sort of little tablets, coated on only one side with a cement like crust. I'd like to etch that off, if I find the right formula.
Heulandite. Hey, this one came labelled, yay! The little sand grain like crystals are suspended in the "fuzz."
Another filthy NOID.
Another furry dirt magnet
The orange bits aren't Cheeto dust, it's crumbles off another sample.
More in a bit......
