most unexpected result j_sum. maybe different solvents will prove to make different crystals

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.

Just as long as it took for the xylene to cool.
Not very long at all.

Nice, that looks very useful! (although I'm sure the people at the store would not understand)

Time lapse would be cool for the growing of the sulfur.
Fine book! The only specialty book I've found at a half priced books of interest was a book having something to do with fields and molecules, I saw it
a few years ago and didn't know what it was. It seems like it had to do with meshes (like in engineering programs) and the fields of electrons or
charge that computer libraries like openbabel can calculate. But it was a while ago.

Beware! Such buying can become addictive and compulsive.

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.

Nice crystals Starcruiser.
They look great in black and white.
People forget that we see in B/W much better than in colour.

I can see this is a Fetish.
Stop before you go blind.
Edit :
Has anyone tried making a saturated solution, then dilute it just a tiny bit, then slowly dripped it from a height to make a stalagmite ?
It might work with KNO3, sodium acetate sounds easier.

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

OK. The Race is On.
aga vs Starcruiser in the Stalagmite Challenge !
(dac 5.38)
3 days to produce a stalagmite of any substance of your choice, provided that it starts as a Flat plate and a solvated liquid.
3, 2, 1, Go !
I'm thinking sodium acetate and calculating the evaporation over 1 metre.
Splashes ! Damn. Need a Tall bucket or something.

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.
