Mood: Pretty much all of them!

Thanks! The 2-Ethylhexanol was a byproduct of making Phthalic Acid from Bis(2-ethylhexyl)phthalate.

No I don't. My father who is a dermatologist obtained this sample from a patient.

Cool. What brand microscope do you have?

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.

Thanks, and yes, I used my cellphone camera, but I have this little macro lense that fits on its camera so I can take decent close up pictures with it. It's really nice to have for getting good crystal pictures.

Mood: Polymerizing

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!

Yes, I do, and I have already transferred it to a vial. Some of the crystals broke up a bit, but they remained intact for the most part.

Nice. Mine's small at the moment, but I have a very large amount of basic copper carbonate drying.

Mood: So cold outside

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.

Perhaps it's just a hydroxide or basic carbonate?
Pretty, regardless! Also, nice beaker! I'm rather fond of the tall, thin ones, though one always needs the short, wider ones for evaporation.

Yeah the reason I got that was kinda funny.

I was in this Chemical Shop and the shop owner just went to get me some Pyridine and
other Stuff I ordered when I saw that there were these beakers. I wasn't sure how much it fit
because of the hight so I thought I'd buy it. It's really usefull if you want to work with small scales
but need to have a high solvent coloumn. Usually I don't work with my Cyanides in these quantities but
in that specific case it was easier to handle the KCN solution in a higher beaker than in a lower one.

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.

Looks like a small centrifuge tube.

It's a centrifuge tube with a glass stopper. Elemental Scientific sells them, they're quite expensive from them though IMO.

Cool I have two of them and a another one that is a test tube, a bit bigger also with glass stopper and graduated on the sides. Costed me like max. 5$each, I think it was even cheeper. Two pharmacies closed last year and I spent around 100-120$ buying their glass ware, ceramics, old bottles, especially those you used for Acids, that have another cap on them. They even offered me their fume hood but I didn't want to buy it.

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!

Well, that certainly ain't a pretty picture. I wonder if the shipping is better within the US, or if it's still bad and they're just trying to scam. Do you have a link?

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

Actually 2 Pharmacies closed. And I dont use that Shop too often.
I just ordered some Benzene thats something you wouldnt get in
that shop. But I guess I can get pretty much anything as long as I need it for my research.

And as for someone who knows quite many chemosts I usually get told when something is sold.

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.

Nice pictures! Those crystals are really cool. When I ordered Ferric Ammonium Sulfate, I gt some really big crystals too.

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.
