It's a tough call as to who has the better job...

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:

Cool! Very small, too bad. How much holmium do you own?

Looks similar to phenolphtalein cristals falling in NaOH solution :D

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

Could you elaborate more on what the blue and yellow dyes consist of?

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 !
