Those crystals look so cool. I love that green color.

Well, they already started to convert to FeCl3. Now they look a bit darker.
Too bad I can't keep them like this forever

I guess you could keep them in a container flushed with nitrogen or carbon dioxide to prevent aerial oxidation. That would keep the nice green colour

Bismuthate, the iodine crystal was created by melting the iodine under sulfuric acid. The bismuth nitrate and potassium thiocyanate formed this odd
yellow solution with a white precipitate when mixed;

Calcium acetate: I made some attempts to prepare Aluminium acetate for making water proof cloth. When I was doing so, I had left some
calcium acetate solution in a beaker (prepared by mixing calcium hydroxide and concentrated acetic acid) for later use. But, I completely forgot about
it. After a couple of weeks, wow! calcium acetate crystallized out beautifully and you can see that in the pic 
Ammonium tetraborate: I've crystallized this compound for my video posted a couple of days back in youtube

Thats amazing, and not only for the beauty, it looks like you have the cleanest lab around to grow that accidentally without dust contamination or
whatnot.

How does it turn red? Is it mixed longer and/or heated?
Also, Pinkhippo11, how did you cool the KMnO4 over 8 hours? Was it in a kiln type of environment?
Also, has anyone read/seen about the salts made from BiI3 and halide salts? Bismuth(III) iodide forms iodobismuth(III) anions when heated with halide
donors:[10]
2 NaI + BiI3 → Na2[BiI5]

I found this after drinking the coffee that was in my window at least a few days. It was freezing and thawing and was partly thawed when I took it out
to drink. I think I did the best I could to get the crystals pictures and it still doesn't look the way I see it. The camera only is 1 MP.
    
also there are these
it looks different in front of the computer compared to a light bulb. it is not a pure compound but has insoluble brown powder in it

@The Volatile Chemist :
Not really sure. A friend sent it with some other chemicals. I didn't really know what to do with it so I thought since
I only have Sodium Arsenite and Sodium Biarsenate at home some more Arsenic Compounds would be good for the
collection. Actually tried to make Arsenic Acid from it but it somehow didn't turn out that well.
I though of dissolving it in Aqua Regia to gain like a crude form of Arsenic acid, than neutralizing it and hopefully precipitating it with Barium ( I
think Barium Arsenate should be quite insoluble ). Filtering that of and mixing it again
with Sulfuric Acid to get insoluble Bariumsulfate and a clear Phase of Arsenic Acid. But while the reaction above white crystals fell out. I washed
them but I'm not really sure what they are.
I've read that if you prepare Arsenic acid from the Oxide you will get crystalls of the Acid Hydrate so since the products for the Metal + acid and
the oxide + acid are pretty much the same the crystalls could indeed be Arsenic Acid. But I can't find much in literature.
I've made a second attempt now with just Nitric Acid and we'll see whether there are crystalls, too or not.
The Ore is pretty clean, some dark grey stones with shining parts in it. At some points there are like yellow impurities but I've sorted them out. It
should be somewhere from Germany (but I can ask for that).
EDIT:
Some Arsenic in conc. Nitric acid at room temperature and on the right close to it's boiling point. On the right is a indicator paper. That happens
if you hold a dry indicator paper into Nitrous Gases. It get's pink and then white. Saw that at the university where I found dozens of pink strips
after people worked with Aqua Regia. So I tested that out some time ago and found that they get that weird color when treated with Nitrous Gases. I
guess the dye is destroyed in the reaction thus forming a color that is usually not found on the universal indicator.

Yea.
what do you think about putting a calculated amount of liquid chlorine in a super cold bomb flask?
(accounting for PTFE expansion/contraction, wiggling/turning/loosening on warming) I saw a corning glass article on the practice of acclimating PTFE
joints to/from cold.

I guess not much would be containable due to gas pressure; nonetheless, it seems like a good, highly controllable source of Cl2 gas.

Silver Tree
I'm not sure if pictures of this have been posted before but here's some I took of my Silver Tree.
The first one is when the crystals are still big enough to reflect light and in the second one the crystals are smaller and absorb light more, giving
it a grey colour. Reminds me of a big storm cloud or something!

Nice TheAustralianScientist, looks to me like the ash and dust in a nuclear mushroom cloud! When I do the silver tree I use a less
concentrated solution of silver nitrate (about 0.1 molar) and it makes larger crystals which reflect more light.
How'd you condense the chlorine Hawkguy? I've used dry ice in acetone with some success for that in the past. Don't use styrofoam
Hehe.

Thanks! I thought it looked really nice. I used 1.6g of Silver(I) Nitrate in 50mL of distilled water which equals a 0.19M solution. I might try it
again with a more dilute solution. I got a really good recovery of silver crystals, 0.995g, which I was really pleased with.
