I certainly did not do that, I was really beginning when I did this one. If my memory is good, I dissolved magnesium in HCl, then electroplated with a
magnesium strip as the anode. I took a look at the theory and it looks like you are right and I made hydroxide :p I'll have to redo this one. I still
wonder what is on the coin however.

Nothing special, just iodine sublimating and depositing onto a round-bottom flask full of ice.

The blood red reaction product is poured on ice-water to quench the reaction and to decompose the red colored iminium ion what was made by a
Vilsmeier–Haack reaction.
At the bottom of the water the yellowish impure reaction product separates what will be recrystallized to yield white snowflake like crystals.

@kristofvagyok, that looks awesome!
@alexleyenda, Thanks, I wont to start a electro-deposited coin collection as well. Maybe I'll post a picture as soon as it gets big enough. I don't
know, I just never thought of putting weights on my stand.
@ParadoxChem126, I'm to scared to sublimate any of my Iodine, scared that I might lose some that is. I have ~30 grams, that I bought a while ago, but
I don't think that I'll be able to buy any more. (Because of the drug war.) I know how to make it of course, but what I have is very pure, and was
quite expensive.

alexleyenda, for the plated coin collection, why not use silver? That should work fine. Other ones that may work include chromium, cobalt, and gold
(if you can get your hands on a gold compound).
At the end of the day, simulating atoms doesn't beat working with the real things...

For silver I would need nitric acid to dissolve it to make the aqueous solution (at my knowledge it is the only way to dissolve it), but I don't have
nitric acid. It is impossible to find nitric acid or nitrates to make it in Canada (omg, explosives, fear, terrorism, let's ban all the nitrates, next
step is water, dangerous solvent!), I know how I could get some but it'll take some time :p Gold I can't now for the same reason and I'll take a look
at chromium and cobalt.
@ Kristof, your christmas ball over snowflakes synthesis looks really great :p

Not very pretty, but still.. Something with copper sulfate and sodium hydroxide.

Zinc flame
While I was trying to extract zinc from batteries the other day, I had to test if the metal really was zinc. I thought a good first test would be to
try to melt it with a blowtorch. My first attempt did not melt the metal, it was probably a steel case. On my seconth attempt however (with metal from
another brand and kind), it was zinc and I learned by surprise that zinc did burn in a beautiful cyan color! Chemistry is so awesome for these "oh, I
didn't expect that" moments Anyways, I took some pictures of burning zinc
after that. The quality kind of sucks, but it is still acceptable.

Cool, I just took apart two zinc-carbon batteries two days ago, the zinc yields were pretty good, I haven't weighed them yet though.

Been handling lots of bromine lately. I stored it in the freezer to find these pretty crystals on the walls

That looks awesome, I just ordered a condenser, so I might make some bromine myself.

I'm going to electro-plate some coins today(at least one today). Will post some pictures later.

My Québec version of the famous blue bottle experiment ; the beer bottle I
used our maple syrup as a source of glucose as I didn't manage to find pure glucose but it's even better ! It really looks like beer :p

Hegi, you must show us what the sodium ferrioxalate looks like under UV light!
Here's the spectrum of a sodium lamp. The D line is visibly split. I don't know whether this is caused by the absorption of the light or by the actual
splitting of the D line into D1 and D2 components. It's only visible when the lamp is at full power.

A sealed test tube I made today to contain Iodine for the pleasure of safely subliming it. Works like a charm! Resists the pressure, no flaw.

Some copper aspirinate I made the other day. Also, an improvised dean-stark trap. It worked just fine for my synth of p-toluenesulfonic acid.

That's a damned nice product—beautiful color! What are your plans for such a large quantity, though?

Hey man, thank you for the idea, i´ve almost totally forget about that... soon... Now it´s being recrystallised..
