just got a very nice picture of iron that has changed from solid to liquid in a small area (ie. cutting with an acetylene torch)
and the the crystalline structure inside a solidified lump of iron that came from cutting.
sorry about the size

I'm also interested in your process Wizzard! Those are gorgeous big crystals of sulfur, and I really want to do something like that for my element
collection. Much more interesting than a powder!

crystals of potassium chlorate from the bleach method
this method is very inefficient. this is from about 5-6 cups of bleach @ 6%. there may be a couple of grams to scrape out of my crystallization dish.

does anyone know what solvent can clean my Tetramine copper nitrate crystals? i used a little too much ammonium nitrate and the purple crystals are
covered by a blanket of blue stuff.

Normally acetone do a good job to clean tetraamine copper salts.
I never asked for this.

I put together a weather glass a while back and it is supposed to react to weather conditions with different crystal patterns and whatnot. I have
forgotten about it for a few months and today we had a big storm and I got the idea to go see what is was doing. It is supposed to start crystalling
in response to weather coming in 1-2 days so i don't know when it started to crystallize, it is normally a clear solution though. It was "snowing"
these snowflake pattern crystals which, according to the prep I used indicates precipitation! I'm not sure that this is a reliable way to predict
weather but pretty nonetheless!
The second picture is one of some crystals of KClO3 I had crystallizing in the fridge after 2 days of electrolysis with MMO electrodes Long needle crystals, looked quite nicer in person but you get the idea.

Interesting, Mailinmypocket, I was just preparing to make my own version. It responds to the temperature and is a very unreliable method, but so
pretty.
Here's something special, although the photo is a disaster.
It's a phosphorus ring I'm holding above a wet floor. It reminded me of annular eclipse sunsets.
Unfortunatelly, it snapped. You can see it here. 1, 2

Endimion17, you really have an obsession with preparing white phosphorus. I made some WP myself, about a quarter of a gram, the glow was simply
stunning, but the smell of P2O10 and the hazards of WP still give me the chills. That's when I know I'll won't make white phosphorus for fun unless I
have a really good use for it.
Altogether, how many pounds of phosphorus do you think you've made so far?

This is it. I don't know the exact mass because I didn't really care to measure it before the last purification. My last very pure batch (check the
phosphorus preparation thread) is less than 4 g. It might seem much, but it really isn't. The entire volume I've ever made, combined, is probably less
than one smaller human finger.
I've made a benzene solution of it and spilled it outside in the dark. Holy crap, it's awesome in the breeze (I was upwind, mainly to avoid benzene,
the amount of P is actually negligible). It reminds of the tales of will-o'-the-wisp. Cold, eerie fire that lasts for 10 minutes or more. My cat
displayed a significant amount of interest.
One more photo, of the nitric acid method of purification.
Now if you'll excuse me, I'm off to watch the opening of the Olympic games. So far, it's been awesome.

Some nice samples, unfortunately my coal-fired camera takes terrible images of them...
First is a large Bismuth crystal I grew, it is about 4cm across at the bottom.
Second is a beautiful sample of Vanadinita I purchased - the hexagonal crystal structure is evident.

Sometimes the program puts an extra quote bubble around what you say, it's odd. Has anyone else had the same problem?

It happens when you accidentally delete a closing tag too much. The forum software appears to "fix" it by itself. If you quote the faulty post, you'll
see that there are three starting tags but only two closing tags.

Freshly grown tin crystals
Made some floating tin sponges tonight, this is the underside of the first one made in 10 minutes. I wish I was able to take closer up pictures of the
crystals though.
I have another set going now, hopefully there are larger crystals!

Oh, Mailinmypocket, if you could only take a macro photo to show the intricate details. :O They seem to look like a forest of Christmas trees. How did
you make them?
BTW here's something I've promised to post few days ago.
(full size photo)
Also, here's a photo of me cutting the sample with a knife. I think this was 30s exposure time, so the glow is too powerful. Nevertheless, an interesting photo.
I've borrowed my friend's camera. The sample's wet parts seem to have a much greater amount of color, but that's because of the greenish glow
illuminating the insides of it.
As it's hard to catch the "real" color (makes you thing about the general concept of what's real), I tried to simulate it and I think I've hit the
nail on the head. The exposure time might've been a tad bit too long, but that's ok. When you accustom your sight to the darkness, it really glows
like this.
My only regret is that I can't find the way to capture the glowing fumes. A high definition video would be awesome, but that's impossible with today's
cameras. One day we'll see that, too.

Thanks they really do look awesome in bright light, so intricate and shiny, the
other batch came out more flakey and less "needle-ish". Not really photo worthy..
its actually very simple to do, I have attached the PDF instructions but I do not follow this exactly... sometimes I use more or less SnCl2, to see
how it turns out. I also dont bother filtering the acidified SnCl2 solution unless I really want to watch the growth (which happens really quickly).
If you dont filter it it will just be milky, but does clear up somewhat when the tin crystals have stopped growing.
I used granular Zn instead of mossy as is suggested in the paper, next time i will try Zn dust and see how that goes.
Nice P pictures btw! You really have a perfect processes

OTC Copper Mirror
Well, a partial one anyway. A 5mm wide band of good "mirror" with the area above and below coated in a somewhat granular layer. Still fiddling with
the process.
Copper / Ammonium complex reduced with Ascorbic acid.
