A nice shot of a crystal of naphthalene growing on the end of a thermometer.

Sorry about the link
Erythritol recrystallization from Truvia sweetener, the black and red chunks are from an oven mitt I was wearing when dissolving the Truvia, they pose no threat to the erythritol or ETN synthesis because they're totally insoluble. Largest crystal looked to be a little over an inch, I'll weigh them when they're dry. Shot on an iPhone 4S but I can get better photos later.

Some Potassium dichromate I made from Chromium(III)oxide and Potassium nitrate. That is the unfiltered product with some unreacted oxide on the bottom.

Two images from my fun times with my buddy's DSLR:

Giant images - Enjoy this link :)
http://imgur.com/OdxIrgw,x3ACKvM#0

First is a 30-second exposure of Am241 modules under a silver-activated screen. Screen is about 1.5" across. 1-second light painting to pick up the rest of the image.

Second image is a 10 second exposure of a Tritium glass vial, with the phosphor coating. Resting material is white cotton, length about 6".

In keeping with the spirit of the Tritium pictures here is my small sample, used on my periodic table display, since it is my favorite isotope of Hydrogen.





And here is a recent element addition that's quite beautiful, a very large sample of Zirconium metal.

That Zirconium looks nice :D Would love to have that in my collection.

Some Chromium(II)chloride that has absorbed so much water that it's nearly impossible to cruch the chuncks. I think it's time for a new bottle :(
But still a beautiful green when you look inside the bottle.

Some Dimethylglyoxime with [Ni(NH3)4]2+
The upper layer is the Ni-DADO and the purple layer below the Ammonia-Complex. ( For some reason the image is flipped, I don't know why )
http://i.imgur.com/FbJwxKn.jpg

That orange stuff is a Cobalt(III) solution. Unfortunately I forgot how I made it. ( Image flipped,too )
http://i.imgur.com/zl4TgN6.jpg

Last picture is some Bromohexane...well it was supposed to be that. I made it by reacting Bromine with Hexane. Some weeks later these black dots appeared and formed a dark layer. It also started to smell quite stange. Must be some side product or contamination.
http://i.imgur.com/1nFtQ2U.jpg

I will upload more colored coordination compounds soon. And sorry for the image flipping. I will try to correct it.

Terbium piece


I got 5.7 grams of terbium for a science project. I took this with my phone which has a really good macro setting.
The sample is graphite-gray and darker than I expected. Probably some oxide contamination.
Grid size is ¼" per square.

fluorescence: That chromium chloride looks appetizing...

@Brain&Force: Thanks, I don't plan to taste it soon xD. I bought that a chemistry store quite cheap. The kept it in a hughe bottle and gave me the rests of it. I could have bought a waterfree chloride but that would have costed too much. But perhaps it's time to buy a new one.

That Terbium looks oxidized. If you need it for a project why didn't you store it under inert gas oder oil ?
How much did it cost you ?

Dopachrome


Fluorescence, terbium is not very reactive towards dry air and doesn't seem to corrode, especially not in my location's dry air. See Dave Hamric's lanthanide corrosion test. It's mostly the rare earths from lanthanum to europium that corrode quickly. Also the terbium looks dark because I couldn't get good lighting. But it's not as bright as seen in some pictures. Terbium(III,IV) oxide is black like manganese dioxide and a little oxide makes it turn very dark.

Terbium costs $32/5g where I got it. This is the only reasonable place to buy terbium, even for laboratories. At Sigma and other suppliers it costs about $500/1g.:o

And to keep with the thread, here is dopachrome formed by the addition of tyrosinase (sourced from mushrooms) to levodopa.

Formation of Elemental Sodium by Electrolysis Into an Incandescent Lightbulb

Not exactly original, but it's one of the most showy and blinding preparations I've seen in my time at the bench.

Some vacuum distilled phenol crystals in a 50ml RBF. These were prepared by decarboxylating salicylic acid. I am working on trying to boost the yield. It currently stands at 57%

Thank you. :)

The lights were actually on in the room, but of course the camera tries to balance the image against the brightest source in the shot. When that's an incandescing filament, everything else is dark. I rather liked the eery effect though, so I didn't do anything to try to fix it.

From right to left: the hydrogen comes in, bubbles through the flask and the reaction mixture, the reagent is added slowly to the mixture from the top placed addition funnel and the hydrogen what didn’t reacts exits at the left side through a bubbler.

Sadly it overreacted even with these mild conditions and I didn’t get the product what I needed):
