Hi.
There is few photos of my crystals. The blue crystals are CuSO4.5H2O - the bigger one grew one year, maybe longer. They grew up on copper wire - it
wasn't the best option, but they were my first crystals. First was gift for friend and second will be for my girlfriend  .
The violet one in transparent crystal is K(Al,Cr)(SO4)2.12H2O. It is coated by potassium alum. I made it by mixing potassium alum and chrome alum in
ratio 10:1. Another gift for my friend.
The pale violet crystals are NH4Fe(SO4)2.12H2O. This two crystals are growing really fast - they are one day old and still growing in solution.
The pale violet and rusty crystals in bowl are also ammonium-ferric sulfate. After I pulled out these crystals out of solution, they were rusty
(because of colour of solution) but after a some time were pale violet. Later their colour disappeared and after few hours they were rusty. This
compound really quickly loses water.
The green crystals are CuCl2.2H2O. They are currently turquoise.

the potassium-chromium crystal in a crystal is really cool

Ubya: Thanks .
Ammonium-ferric sulfate growing up very fast! I just love these crystals . Here
is few photos from this morning.

Crude cinnamic acid, basically solidified blobs of acid mixed with cinnamaldehyde, with crystals of pure acid growing from them.
Please remember: "Filtrate" is not a verb.

Running some tests on an otc product to figure out what might work for an extraction.

@jsum so what exactly are you extracting? And why are some yellow?

I am being deliberately vague because I think I have found something cool and I would love to solve it myself. It is an otc product based on an ionic
liquid with a somewhat oily consistency and unknown other ingredients. My tests show that it forms emulsions easily.

Some nice FeSO4 crystals from a few years ago, made from steel wool and drain cleaner sulfuric acid as per this link. Alas, they're all brown and spoiled now. Picture has been edited to improve quality (brightness/contrast).
Eventually I should save them by redissolving in dilute sulfuric acid, filtering off the crud, reducing the Fe3+ with a little extra iron,
and making some Mohr's salt ((NH4)2Fe(SO4)2·6H2O)

When I recrystallized my FeSO4x7H2O, I washed the crystals with some isopropanol then left them to dry. Even after 6 months they still haven't turned
brown.

A failed attempt at Copper Peroxide yielded this
I am at a loss how to make the synthesis work in water. It hates being filtered and decomposes really quick. Make it with too concentrated peroxide
and it goes whoosh. At least it looks pretty this way. Some of the desired product can be seen on the glass rod where it escaped the water.

Ice spikes
One frosty morning recently I spotted some ice spikes that had grown out of some water that had frozen in an up turned plastic access cover in my
garden. Previously I had only seen pics of them.
I am wg48 but not on my usual pc hence the temp handle.
Thank goodness for Fleming and the fungi.

I second that - please provide your procedure! As far as NaBH4 and HCHO are concerned, they'll just make carbolines with your substrate, so i hope
you've done careful analysis. I just recently learned that the claimed product is itself neurotoxic as well.

CsCu(SO4)2.6H2O, a Tutton salt
The large crystal is 2cm across and was grown in 2 days. I think that's much too fast to obtain fully transparent crystals.
Tutton himself described the colour as greenish blue. I can't photograph that, but under incandescent light the colour is indeed greenish blue. The
picture was taken under a fluorescent lamp light.
The crystal habit Tutton describes in his 1893 article is in the drawing (Fig. 31).

The two extremes of Cobalt Violet, a cobalt(II) phosphate pigment. The pink one was prepared by adding aqueous ammonia to excess pink(relatively
dilute) CoCl2 and NaH2PO4 solution, while the deep purple one was prepared by adding solid KOH to a boiling hot solution of the two that had been
saturated with salt.

Great colours!
And do you know the composition of both compounds, their formula?

An attempt at K2Cu(malonate)2. Nice xtals, but they turned much paler blue after drying.

And maybe get rid of the non chemistry pictures ?
