PostForum: University Arizona Tucson Mineral Museum   Posted: Sep 07, 2021 15:14   Subject: Re: Announcing the opening of the New Gem and Mineral Museum of the University of Arizona
What struck me about their publicity is that they do not know the locality for any of their specimens! Did they misplace the labels?

We could help them with some localities, I guess.

I have one - it is a volcanic bomb from a volcano in Fife, Scotland (Hill of Tarvit), so about 300 million years ago it must have shot out from the volcano

It might be easier for you to take the tray of minerals to a local mineral dealer or museum? They can then help you identify things. If that is not easy, keep doing tests and posting

If the second one in harder than quartz, then tourmaline is likely. For the first, which is less hard than quartz, it is unlikely.

Check their streaks as that may help a bit

Chalcedony is a form of microcrystalline quartz and this looks like quartz, so it might contain chalcedony. I have no idea where it is from as it could be from millions of different places

Given the taste, halite seems likely. Could the crystals be partially dissolved in water?

If you do a few tests we might be able to help - hardness should be the first test as that will help rule out the very hard minerals (I suspect it will rule out your guess).

Quartz and Feldspar.

What is not said is where it washed up. That might give a clue as to its source, but might not! I have found pumice on the beaches of Fife, typically on the northern coast near Crail and round the c ...

Sadly my grandmother had radium therapy for a weak chest in the 1900s. She died of cancer of the chest about 80 years later. Link not proven but possible.
