Bismuth is pretty fucking cool.
I want to create bismuth crystals but i'm not a chemfag so I don't know how.

>>8990608
I thought about making some crystas too. looks really easy, plus you can make some neat magnets.

Hello, rock nerds.

I want to ask, are there minerals that glow in the dark?
Note, not under special UV light, but rather in a more natural occurring "dark", like a basement, a mine, and so on.
Is such a thing possible? To have a mineral that makes sense, which seemingly creates light humans can use to see things, but doesn't kill humans by doing so.

I am writing something and want it to make sense.

>>8994011
I think a phosphorescent cristal wouldn't be technically impossible, but it would require to be exposed to light beforehand.

Other than that you could imagine a cristal that, when exposed to air would react and produce light, but from what I know chemiluminescence happens mostly in organic compounds.
depends on the level of realism you want to involve in your writing.

>>8994039
just after posting, I realized I was dumb and that the most common case of chemiluminescence is actually a mineral, white phosphorus.
But it doesn't really sound like what you're looking for.

>>8994039
>>8994050
I am after the following scenario: people walk down a cave, they find glowing rocks, and use them as makeshift flashlights. Of course I don't mean a bright stream of light, rather something you dangle close to what you are trying to see, like people do with phone screens today

Although a rock that you can "store light" in also could be utilized in another scenario.

How long does Phosphorus effectively glow? A fist sized rock wouldn't just burn out in days, I imagine?
Also, is it a dangerous, unstable thing? When I read White Phosphorus, I think of war movies and an explosive named that way.

>>8994039
>phosphorescent cristal wouldn't be technically impossible, but it would require to be exposed to light beforehand.

What if it's a phosphorescent crystal with triboluminescence properties? You break the soft stone in half and the initial spark causes the phosphorescent mineral to glow for half an hour. When the light runs out you split the stone again causing another spark and 30 more minutes of glowing. And if you throw the stone to the ground it'll make a bright flash like a flash bang grenade. I know triboluminescence isn't that strong in real life, but this is a book. Creative liberties are allowed.

>>8994079
phosphorecence ain't magic. it doesn't create light, itkinda "stores" it, so if small fraction of the initial spark it managed to capture is strong enough to shine half an hour, the spark was also probably able to turn your eyes into shish-kebab.
And triboluminescence is pretty weak.

>>8994054
white phosphorus glows low green when exposed to the oxygen of air, and that last until there is no phophorus anymore (it's a chemical reaction). I couldn't however gave you an estimate of how long a certain mass would last, but I guess it could work the way you want it.

However, it has a slight tendency to self-ignite when exposed to oxygen, and, when burning, glow with a distinct shade of "my eyes! I'm blind! Why, AAAAH, why?". So yeah, not stable for long, so that would be possible only if the cave was sealed shut and with an anoxic atmosphere and just recently opened, which is not so unlikely given the good circumstances.
And btw, your guys shouldn't hold it directly. That is, unless you want somebody to lose a hand, in which case it's a good way to do it.

I disagree Granite is much more Felsic than this. this is pretty dark so it's most likely mafic. Also the red inclusions have a different look than the potassium feldspar found in granites, in both the color (it's a darker red) and the crystal structure(this looks lumpy, grainy almost)
