That's one of the coolest crystals I've ever seen

Oxidation states of vanadium:
+5, +4, +3, +2

I am not terribly happy with the green, but it is still rather nice to have them all on display.

Nice! Are the lower ones backfilled with nitrogen or argon? If not, I’d worry the colors won’t last for long.

The +2 has a little sliver of zinc still in there. It seems to be stable. I have a second without the zinc to compare with.
The +3 was more tricky to produce. I found that it would oxidise back to the blue within seconds after removing the zinc strip that I was using to reduce it. I ended up doing the reduction in the ampoule and sealing it as soon as it looked right. There is a tiny piece of zinc in there too which should mitigate against the trapped oxygen. That one was a balancing act. And I definitely did not capture the best shade of green.

[edit]
You were right to be suspicious, Texium.
This photo shows the two ampoules a couple of hours later: one with a zinc strip and one without.

It is possible that V2+ react with water. But I am not sure about it. I did recently some titanometric titrations and I also want to try chromometry, but CrCl2 solution decompose in 24 hours even under inert atmosphere. But TiCl3 is very stable under inert atmosphere.

Btw. you can make V(III) fairly quickly just by mixing V(II) with V(V) in stoichiometric amount.

K2UO2(SO4)2
The fluorescence is incredible in person, unfortunately shining uv directly on it floods the picture with purple light so I had to shine it to the side.

Did you post after drinking the bottle ? :)

To drink "Atom" wine I would have gone for these glasses:

I found this South African Jam Jar wine that paired nicely with a jam jar jet effect.

Western Cape, South Africa - Crafted in a lighter style this Shiraz is a fresh, fruity, sweet wine that displays aromas and flavors of ripe blueberries, blackberries and raspberries with dark chocolate undertones. Refreshing and approachable with a perfect balance.

@Herr Haber: When I took the pic, the bottle was opened. ...but that was before dinner....it is no longer unopened. Are those goblets the ones that are colored with U salts? I seem to remember something about that. But I just might look for a bottle of that wine locally. Thx for the video and link'


@Morgan: I do like Shiraz, but I prefer a dry rather than a sweet red. Thx for the links. I may look for a bottle locally.

Yes. You can easily find uranium glass also called vaseline or depression glass on eBay.
NileRed made a video on how to make such glass.

Went back over to the coast and cleaned out my poor Toyota pickup. I haven't been hanging drywall over there for 3-4 years. One of the things discovered was an plastic pan with some solution in it and what sounded like glass rolling around. I assume it chrome alum? Nice lavender purple color. There was a small pile of agate's I found on the beaches, and in the glovebox I found a pile of carbonized ground cherry skeletons probably already pictured in the bread pyrolysis thread.

It sure used to get boring over there away from the fam, and my scienceing budget was dollar store or thrift store max, lol. See if I can't clean up a couple crystals and get a decent pic without the yellow solution adhering.

tris(bipy)nickel(II) sulphate


surprisingly soluble in organic solvents- these were grown by vapour diffusion of acetone into a methanolic solution. I'm going to try again, starting with a more dilute solution, so there isn't the sudden rush of crappy crystals with better ones growing on top.

So a while back I posted this shortly after
I rigged up a drying tube to diaphragm pump, pid heater and insulated bucket.
Every hour 10ml of dry air is pumped in and 10ml of moist air is pumped out. Keep the temperature at 28c, Set it in the corner and completely forgot about it.
Inside was a beaker, containing a saturated solution of KCl obtained from multiple recrystallizations of "Muriate of Potash 0-0-60"
