New element collecting site!
If you are a fan of Mr. Theodore Gray and his amazing collection, you will appreciate this very much indeed…an acquaintance of mine in Russia
decided to put some nice picture of his collection online.
His English is not perfect, and the site is still certainly under construction, but his samples are absolutely outstanding, simply some of the best in
the world.

Yeah but look at some of his samples. My personal favorite is the liquid oxygen in the tranparent dewar--you can actually see the blue color!

Yeah I saw that too, very impressive. Hmmm, he doesn't have any palladium you know...and he did say he would gladly trade for a good sample! (HINT
lol)

Heh. I am tempted to trade some palladium for that liquid chlorine ampoule.

He's selling them for $80 as well. So maybe you could get an ampoule + ~$200 for an ounce of Pd…

Ah.. I know this guy. I purchased a sample with a tiny amount of liquid chlorine (just a single drop), a sample with bromine, a sample with thallium
and a sample with iridium from him. I hope to receive my samples next week.
He is a very cooperative guy and he has fair prices. He is not a professional seller, like the other companies in this business, but he has spare
materials and is willing to share them for decent prices.

I agree with what woelen has said. I sent him an e-mail so he could have a copy of my element collection images and then asked what samples he has
available. I was able to pick up a liquid chlorine ampoule, an ampoule of unoxidized lithium metal, and an ampoule of unoxidized potassium metal.
I'll hopefully be getting the chlorine and lithium later this week.  He told
me he's going to work on the potassium ampoule to come up with a nice sample at a good price.
I do want to mention, however, that he would prefer to do trades over direct sales. I'd feel really bad if the poor guy got hammered with requests as
like woelen said, he does this on the side and isn't a professional retailer. Still, he seems to be a great guy and has some simply AMAZING samples
on his site. It's nice when you can make contact with fellow collectors and help each other out.

Thats a fantastic display. The liquid Oxygen is excellent, where could you find something like that? All the samples i have seen have been gaseous.
I noticed that he puts these samples together himself. Has anyone else tried this?
What is the best display method ? For example if i wanted to make a potassium sample, what would be the best way? I presume i could cut it into cube
under paraffin so that the surface does not oxidise and remains shiny, but where would you go from there...
Any help or advice appreciated.

Having an argon drybox is critical. If you have a drybox you can take your potassium sample outside of the oil storage container, dry it off then cut
off all of the oxidation without any fear of oxygen or water in the air. Inside the drybox, you can then place it in a glass ampoule and using a heat
source melt the ampoule shut. If you would like you can also melt the potassium inside the ampoule so you get the beautiful reflective surface.
Basically, without a drybox you will have a tough, if not impossible, time sealing the reactive metals up. Complete protection from oxygen and water
is required and that's not easy to do.
For the oxygen, you can temporarily view it like that but you can't do it long term. If you have some liquid nitrogen, you can place a glass dewar in
the liquid nitrogen and run some oxygen gas through a coiled copper tubing submerged in the liquid N2. Oxygen will then drip out of the opening of
the tubing as a liquid since liquid N2 is colder than the B.P. of oxygen. If you have a high enough flow of gas you will get enough liquid O2 to fill
up a glass dewar and get a photograph before it all boils away and makes everything in the area HIGHLY flammable.

A dry box! Of course, thanks for the reply!

Woelen, re. emovendo, they say nothing about international shipping. I take it you had it sent to the Netherlands, does it get delivered from the US?
Or a local European retailer? I'd rather not get anything from the US, I don't want to get detained randomly next time I enter the US for a conference
just because I bought some Se. Same goes for smartelements. What was your experience with it?

Smart-Elements is based out of Austria or Germany, I believe, so there is no reason why it would ship through the US. Though the prices are nuts
high.

Emovendo ships to Europe, but yes, it is from the US. I purchased more than 10 element samples from him in a few different shipments. He is not
expensive at all and also the shipping cost is very good (e.g. for the 30 grams of selenium, overseas shipping is only $2 or something like that). You
have to pay by credit card or Paypal. My experience is good. Never had trouble receiving packages, usually, transit time is 10 to 20 business days.

Sorry, back onto the subject ....
What do you think is the best think to use to "display" / store the samples.
Maybe i should say, what is the easiest thing to get hold of that still looks good. Those glass ampules look great but don`t have a clue where to get
them from!

There's a place near me (and all over the U.S., I think) called The Container Store that has all sorts of glass and plastic vials, jars, acrylic
display cases…i bought a sturdy plastic toolbox from them to hold my element collection and ship (all 51 pounds of!) it to college in.
Lots of places! Keep your eyes out.

Yup. Just do a quick search on Google and you'll find plenty of places that sell all kinds of glass jars and vials. For the actual ampoules, those
can be made by taking a test tube and some propane torches and melting the glass shut. However, keep in mind that this requires quite a bit of
practice and unless you have a constant vacuum or constant flushing of Argon you're going you'll have to deal with some oxidation caused by the heat.

Actually I can exchange small amount of this funny crystals, But till now I could not found good PTFE vials for its shipping. It's VERY SMELLY, and
corrosive.
P.S. Thank you VERY MUCH ! for you interest to my website!

Hehe. Yeah, the slow evolution of fluorine gas from those crystals are actually a kind of neat way to get some fluorine gas as a sample.

I not sure, that crystals smelling due to decomposition of XeF2 (it's stabe at boiling point (>150c) ), I think it's smell of XeF2.

Xenon difluoride is available from Fluka.
1g 94 Euro
5g 355 Euro.
If I had the spare money I could well get some (via pharmacy or else).
However, it's listed as extremely toxic.
And yes, XeF2 is stable until its melting point (129°C).
The smell is due to the considerable vapor pressure of the solid at room temperature: 3,8 mm Hg at 25°C.
