It's a tough call as to who has the better job...
They tried to have me "put to sleep" so I came back to return the favor.

When fermenting berries in the lab, always strain the mash first!

^^By the way, the red stuff was a kind of Iron 2+ complex with a bidental triple cycle ligand, I forgot it's name, anyway it's not my project as I
said :p

Yeah, I had the same experience! Even
when I tried to melt it under argon (using a wine preservation canister). Oh well. It isn't very pretty for the element collection but at least it
still works for chemistry.

Gleb - Beautiful work, there!! I aspire to grow my own as well as yours. Can you tell me anything about the potassium sulfate and nickel sulfate
crystal in your last picture?
Nizzo - Nice Nd sulfate crystals! How do you prevent yours from cracking? My medium sized ones (about that size) like to split along planes.

The same holmium citrate solution, in tube lighting and CFL respectively.

Wizzard, thank you!
I crystallized the stoichiometric amount of nickel sulfate solution and potassium:
NiSO4+K2SO4+6H2O=K2SO4*NiSO4*6H2O (blue-green crystals)
temperature=20 C
quite fine chemicals
isometric evaporation method

Here's some of the holmium citrate solution I'm drying, under CFL light. The above pictures aren't very accurate, as there still was a bunch of
particulate metal pieces that hadn't fully dissolved yet.
Here are the crystals that I've already made:

Yeah. But, heck, phenolphthalein crystals? I only've ever had solutions of it :/
Did you make the Rhodamine, or purchase it?

They are 50:30:20 Powder dye/Potassium chlorate/Lactose powder.
50 grams each wrapped in paper and tightly taped
Top left = Blue dye Top right = Purple dye (Rhodamine B)
Middle = Yellow solvent dye
Bottom = 50:50 Blue/yellow

Yes, please. I would like to know that as well. They look really nice!

I agree !
Today, in my internship, I made a zipper reaction, that is the result of ethylenediamine deprotonated by NaH, it becomes a nice purple !
