Pretty Pictures (2)

I made some iodoform recently, and recrystallized half of it from alcohol. The other half I tried to dry crude, and the base remaining on it appears to have caused it to decompose and release iodine - the filter paper and jar were stained brown. Now, though, there are these lovely formations growing on the lye I was using as a desicant!

Here's the conifer gall of a Gymnosporangium juniperi-virginianae . This fungus spends half its life cycle on apple trees, and the other half on junipers.

Wow, interesting crystals! Maybe the orangish red precipitate is copper (I) oxide?

Some pretty *disgusting* pictures, an extraction after a pdc oxydation (pyridinium dichromate). This reaction is such a pain in the @ to clean. And that is before I tried to wash it. It became worst when I started rubbing it with a brush, the crap stretched accross the glassware -_-

Sodium salt of 1-hydroxy-2-naphthoyl-o-benzoic acid

Precursor to series of fluorescent dyes

Looks just like liquid gold

When dissolved in water gives deep olive-green solution

Manganese (II) Chloride, recrystallization test sample out of batch.
It is such a deliquescent bitch, redissolving whenever it rained. This came out of about a week in a desiccant bag.
The single crystals at the beginning were much prettier but I didn't want to risk taking it out.

I like those crystals pyro!
Here are a few of my own, these are vanillic acid being recrystallized:

Remnants:



And the final drying crystals:

"deliquescent bitch"
Lol, would make a BA band name, or a great pompous curse word to use on certain foul womenfolk

Apparatus for making some ammonia soln. (NH4NO3 + KOH), improvised scrubbers in the background - some 30 years old milk bottles filled with water, suck-back traps in between (probably unnecessary - I`ve also provided some aquarium anti suck-back valves - these work like a charm (but I don`t rely on them if I were generating NO2 or something else more corrosive).

In regard to a request by aga in this thread, here are some pictures pertaining to what I have done this month so far.
I thought I would post them here since most of them are quite pretty and that way I don't have to double post them.

1: My Bromine distillation setup (it was very cold that day, hence no condenser)
2: My yield of Bromine
3: Cobalt(II) Chloride (almost anhydrous)
4: Cobalt(II) Nitrate Hexahydrate
5: Cobalt(II) Nitrate Hexahydrate after crystallization in a petri dish
6: Praseodymium(III) Nitrate (hydrated)
7: Sodium Ruthenate(VI)
8: Top layer = 2-Ethylhexanol, Bottom layer = Aqueous Sodium Phthalate

Come on TAS, give diddi some credit too!

Mitotic skin cancer cells under my microscope at 1000x. You can clearly see the cells at different points in mitosis. The most incredible is a cell near the middle of the picture in anaphase. The spindle fibers are clearly visible! The yellowish tint near the edge is due to my camera not being perfectly in line with the microscope.

You don't have skin cancer, do you? Sasan and TAS, nice pictures! How's you make ethylhexanol? I'd like to!

Here's a couple pictures of sodium cuprioxalate, Na₂[Cu(C₂O₄)₂], which was made by crystallizing a solution of the complex formed by dissolving copper(II) oxalate in excess sodium oxalate solution. As you can see, it forms beautiful needle-like blue crystals, similar in color to copper nitrate, but much more delicate and non-hygroscopic.

Nice one zts16. Did you use a cellphone camera for that second pic? It appears to be zoomed in quite far for a photo taken with a phone.

I've been pretty busy with my first year of university and since I cant afford to buy some equipment for my personal experimenting I've been making stuff again. I'm not very sure if you'd classify them as pretty but I guess they have their own aesthetic going on.

The first picture is the conceptual design I'm going with for a stirrer/heating mantle, the glass part is from a broken sep funnel, the metal can is a sterno can and the plastic supports are from an old Cuisinart cup I found. The second picture is a vacuum aspirator made out of some old pen parts, a bunsen collar, some broken glassware and a few metal fittings and pieces. Oh! and just for fun two pictures of an old thermite volcano display I made a while back.




Thank You......

Nice! Zts16, have a copper compound collection? That compound would look nice in a storage container (Capped vial, ampoule, you know what I mean) if the crystals stayed intact!

Just happened yesterday.
The cam doesn't pick it up very well but the liquid has the
same color as the surface of the precipitate a really
beautiful blue-green hue. In the test tube on the right is the
liquid layer seperated from the solid. As you can probably see
the color is different. The greenish hue is caused by the
orange to brown solid on the bottom of the beaker.

Nice...but I have no clue what it could be. Probably some
Copper Sulfate mixed with other Copper Compounds, dunno.
I was working on a new Cyanide Compound and prepared that
beaker full of KCN-solution. After I was finished I had quite a large
amount of it and wanted to neutralize it. Halfway trough I stopped
since it was to expensive to just neutralize and thought of
precipitating it with copper sulphate. That's when I got that solution.
I did it in a test tube, once with copper sulphate and on the other with some of the neutralizing agents I used. Only the second showed the beautiful blue-green color, the other one didn't.

I guess I'll have to try this without any Cyanide in it. Still it looks pretty nice and was quite a surprise to me.

Does anyone know what that ampoule I'm holding at the right is called ? I got that from a pharmacy that sold all their lab stuff. They are really usefull.

I haven't come across them before but a graduated tt with stopper seems like a splendid idea to me. I started looking and here is what I found!

If you ever want to react a salt with an acid make sure to add the
salt first, otherwise the test tube will be covered with liquid and the
salt will stick on it...something I didn't think of. I just saw that these
beautiful crystals formed. It's a continuous line along the wall and ends in a bigger crystal on the bottom .






Oh and here are the glass test tubes/centrifuge tubes whatsoever



[Edited on 4-8-2015 by fluorescence]

Part of my latest order came some Manganesechloride and Bismuth Nitrate. I knew I got the hydrate form but I didn't expect such large and really neat looking crystals. It's harder to dissolve but it looks really cool. Especially the Bismuth ones. Some are huge and quite transparent.

On the right I put some of the Chloride on about 250-300°C for around 10 minutes and then pulverized the result. I guess most of the water is out now.

I finally get a turn at this. (I should have raided my wife's camera instead of using my antiquated phone. And I should have organised some light rather than trying to take them in near darkness.)

I had a go at making some sulfur crystals today. I was expecting rhombic and not the needles/feathers that I got. Still, rather interesting to look at.
For the interested, garden variety sulfur and xylene -- both from the hardware store.

So, I heard you like pretty pictures

PS: I was intending to post the photos here, but there are too many to resize, so I'll just direct you to the post with all of them.

found a nice book at the thrift store today only $2.50 for 159pg's of decent reading, I can't complain. I have found a few other great books there randomly from time to time.

Beware! Such buying can become addictive and compulsive.
Once started, you may find hard to stop

Time lapse would be cool for the growing of the sulfur.

I might look into that.
Here's the latest effort -- silver crystals via displacement reaction. Nothing spectacular but a bit of a classic. I was pleased with the way that they look.

first batch of crystals after cooling, then after filtered


second batch of crystals from remaining sol, and cool pattern left from a thin film drying



Potassium ferrioxalate I finally got around to crystallizing, in the third pic you can see what happened when I let it cool slowly while trying for larger crystals. from the second wash after filtering. left in the pan on the hotplate with an aluminum lid for a slow cool. I got larger shapes, of small crystals...

also, notice to the left of the container bottom of first image, you can see a decidedly darker green spot. apple green to my eyes. this spot was set apart just lower left of center of the second image. I haven't had time to investigate yet, but it kinda looked like a larger crystal had formed in the mossy aggregate of small crystals.

while watching the solution cool, you could see larger thin sheets materialize rapidly. they looked to be kinda like a square ripped diagonally in a stair step pattern.

I often end up using 1$ coffee maker carafes for their large surface contact and cheap nature. gotta love the thrift store.

the first batch didn't turn out well, apparently hadn't read the part about sunlight and while in solution... bright 103'F day had me confused for a bit, but reading fixed that. pH paper, and the basement did the rest.

It is something I wanted to do for a long time.

Good advice, though... will keep that in mind at least `till my next batch of nice crystals

I tried that sulfur crystalls with Benzene today.
Heated about 5 ml of Benzene with 2 Spatulas of Sulfur
to it's boiling point, had it boil for about 5 minutes and
then wrapped aluminium foil around the test tube.
That's what I got.






Quite nice chunks for the fact that I started with a powder
it looks quite cool

try to go with more solvent in a 50 cc flask, add a small piece of random rock as a seed rock ( ) and cool it down slowly (I used dewar´s botttle)

Thin, plate like crystals of 4-amino 2,6-dinitrophenol, resembling a pure gold pigment powder when dry. Recrystallized from ethanol/water, the wet, thin plates orient themselves as one reflective gold mirror, truly one of the most beautiful compounds I made so far.
