SO3 crystals. Beautiful but treacherous!
The single most important condition for a successful synthesis is good mixing - Nicodem

These look great! Reminds me of my own experiments.
It does look a bit like white mold when the bottom of a flask is covered in crystallized SO3, with all these fine hairlike needles.

I was makeing some tetraammine copper (II) sulfate for furteher experiments with tetraammine copper salts... and was amazed that cystals grew so
beautiful and large!!!

I did something similar with a gold solution I formed a gold mirror in a flask, turning the bottom half of the flask (maybe ~25mL) into gold by
deposition of gold dust on the walls (a black powder when it was rubbed off). I didn't take a picture either.

A gold mirror flask would be amazing! I have a silver mirrored Erlenmeyer
Maybe I can find a picture with Iodine vapor in it. My favorite!

Oleic acid-capped cadmium selenide quantum dots suspended in toluene. Based on the UV-absorbance edge (558 nm), the Brus equation indicates that the
core-crystals are approximately 2.78 nm in diameter.

Nice picture! I"m sure that there are many interesting inorganic compounds that would look awesome under UV. I'll have to pull out mu old UV lamp out!
I see that you have some Pyrex Hach glassware. Do you have the volatile compounds distillation apparatus?
Hach Distillation Apparatus
I have two complete kits (minus hotplate) and would be willing to part with one, would trade for other glassware.

Just left hot and really concentrated solution overnight at room temperature (~8 hours) in round-bottom flask where I made it (added excess of 25%
ammonia to hot saturated solution of CuSO4*5H2O and heated until all solid dissolved). There were no other small crystals, only these large ones in
picture...

Here is electrochemically crystalized silver. I did this few months ago by using electrodes of ~80%Ag/20%Cu alloy and AgNO3 electrolyte. I dont
remember exact voltage...

Here is what I call the copper rainbow, even though the yellow is sort of yellow-green.

More physics than chemistry, I suppose, but here is my homemade Lichtenberg figure, or static discharge on powdered Zn on a ziploc bag

Click "Edit" on your post. Below the typing screen you will see photo uploading slots. Do not use the "Quick Reply" on the bottom; it does not have
all of the features.

Thank you. For your kindness here is a picture of some tetraamine copper(II)nitrate I made a few months ago.

I tried my hand at the macro-photography option of my cam to get this reflected image of
the beatiful structure of Copper Sulphate crystals that have grown in a supersaturated
solution. The original single crystal that was grown on a suspended copper wire in the
solution, was much bigger but sadly, these structures are so fragile that they crumble
very easily.

Very nice! I've done it with rhodamine B
Does diphenyl oxalate give the same light?
