Oh, I would love to have some iodine crystals to work with... Anyway.

well then make them!
there are many, very easy ways to make I2. then just heat to 180-200*C with a flask of cold water on top

you could try NO2 and KI. its very effective

OK, thank you. Atm I need more KI to make this, but I'll try this. The NO2 can be generated by using nitric acid or is there a better way?

lol, yes with nitric acid is abouth the ony way best is nitric acid and sugar,
nitric acid and any cheap metal works well too, but less effective. read my post about it to get all details.

Just some new photos:
In old times when they used nitrocellulose in the cinemas there was a lot “accident’, because the film easily ignited, like on this picture:
And a few crystal at the bottom of my breaker under UV, it is a pyrrole polycarboxylic acid amide, looks like a spiders nest(:
Isn't chemistry just simply beautiful?
I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/

I love the precious metal pictures! Too bad I took down my palladium dissolving in aqua regia video, seems to be a popular topic again. Check the very
first post in the thread.
Iodine is also very beautiful. I love the weird crystals it makes. You can melt it under H2SO4
To make NO2 you can mix Cu, ammonium nitrate and HCl. Then add aluminum foil to get your crude Cu back for another batch. I haven't done this, so I
don't know how vigorous it gets

So long as we are on the Hg topic, here is a 50g brass weight floating in a small crucible boat, on mercury of course  (need to clean the mercury at some point..)

It's visible for maybe 10 seconds, but dims rapidly.

Not exactly. All thats known is that its majorly Fe III.

Ozone generator... Made with a test tube stuffed with Al foil and a wire coiled around the outside. Connected to an induction coil it makes enough
ozone to be uncomfortable...

could you give a more detailed description of your setup? would be worth a try if only for the evil glow =D

Oh...suuuuuuure......... It was supposed to be proprietary and top secret, but what the hell
It's a rather crude set up I made in about 15 minutes. Anything similar to this set up will work, whether its a test tube, glass plate with foil on
either side etc. I used a test tube because it allowed me to coil wire on the outside and fill the inside with foil which has lots of sharp corner and
edges which seems to be where the plasma concentrates itself.
The more blue glow you see, the more ozone you are making.
First a metal wire with a hook with roughly the same curve as the test tube bottom was stuck into the tube. Then aluminum foil was jammed in in small
pieces and compacted quite a bit with a metal rod. This forms one electrode.
Then wire was tightly wound around the tube as shown here. It helps to wind it around the tube, remove the "spring" of wire and tighten it to make it
have a smaller diameter and then push it onto the tube to ensure it stays on tightly without needing tape etc.
At first I tried to use this small transformer chip that came from a small neon tube display... It produced no glow or ozone. Im not sure what voltage
these things operate at but obviously not high enough. The output wires do arc though and give nasty little shocks.
So instead I took out the bigger guns and used a real induction coil (which does give a wicked shock...), this thing easily makes 3 inch long sparks
through the air. I'm not entirely sure of the output voltage but the only power supply I have is 6V, 3A. Just connect the output terminals of your HV
source to either of the electrodes on the tube (doesn't matter which one) and you have a crude ozone generator.
This is just running the coil with alligator clips on a porcelain dish...
PS: If somebody could enlighten me on how to calculate the output voltage of this induction coil it would be appreciated. Im not a big electronics guy
and this was just something I bought on eBay due to good pricing.
I plan to place this tube into a larger glass vessel and use an air pump to circulate air through it and have a dilute source of ozone. This test
alone gave me a horrid sore throat the next morning... which I am directly blaming having my face too close to the damned thing for so long.
Nonetheless.
You can do this too... http://www.bigclive.com/oz.htm

great info. this deserves its own thread. a quick question: since the corona discharge can be intensified by making the electrode more 'spiky'
(ideally a needle), is the dielectric really necessary?
