Looks like it would fit in very well with a model train set or diorama! Who would’ve known that something so inorganic could seem as if you’ve collected it straight from the outdoors, like some weird moss or fungus.



In chemistry, sometimes the solution is the problem.

It’s been a while, but I’m not dead! Updated 7/1/2020. Shout out to Aga, we got along well.

Have you ever tried sublimating benzoic acid in a pickle's jar?
After two days 8 g benzoic acid filled up the jar like this:

Pyrolyse it, exactly as it is.

Either it will be simply destroyed, or you'll have an amazing substance.

The Jar will be a gonner.

1) Crystals of silver grown by reacting copper with silver nitrate solution on a microscope slide.

2) Vanadium(III) solutions with a) excess oxalate and b) excess glycinate.

Failed recrystallization attempt of MCPA.
The liquid separated into two layers upon cooling and after a few days in the cold crystals started to grow.
Then a few days later they grew through the layer seperating barrier into the other layer. It seemingly did not bothered them much. :-)

First crystal of my CoSO4 solution prepared from CoCl2 + Na2CO3, then CoCO3 + H2SO4.
I'll try to make prettier crystals when the solution is all evaporated.

Thanks, I like it too, reminds me of Garnet.
CoCO3 (I know It's not the actual formula) is also quite interesting :) even though it's just a bubbling mess inside of a beaker.

Cleaning some sodium metal made using Nurdrages procedure.
This is on the third wash.
Looks so nice before it gets oxidized by atmospheric O2

I just made some salen. One of the simplest, quickest organic reactions I've ever done. Too bad the reaction of the ligand with copper acetate wasn't as nice.

Hey man! Where did you get reactants? ... I would like to make salen too and make complexes with several metals. Then write down some article about it. Thanks for any help .)

I work at a college, so I cheat- I can basically order anything I like as long as it's not too expensive and I intend to use it for educational purposes (not just my own).

Cool- but I wonder if a 2:1 ratio would give a more salen-like chelate....

not so pretty picture


As a part of my ongoing investigation into the corrosive effects of aqua regia fumes on common objects,
I submit the following annotated photograph.

AR.jpg - 2.6MB

The aqua regia is the green solution in the background,
the colour is due to gold and silver dissolved in the aqua regia.

I suspect that the green colour is due more to copper impurities in the silver and gold, since silver(I) ions are colourless and AuCl4- is orange-yellow.

D'oh !

Of course the colour is due to copper not silver - brain fart :(

I've recovered gold from scrap many times
(but my total gold collected is only just over one gram)
and I love the colour of chloroauric acid in solution - like urine but with with a sheen.
