The secondary alcohols and magnesium all from e-bay. I have been searching around a bit for rules, as I don't live in the most chemistry friendly part
of the world, but I couldn't find any reasons why any of those things shouldn't ship here.

How many sparklers would you have to burn at a birthday to make the equivalent of 1 kg of Ce ?

Just ordered 10grams Vanadium pentoxide
and just added 50grams Iodine to that
Not a chemical but a large purchase, I'm broke and going to suffer for it for a week but screw it good deal!

100g K2TeO4.5H2O
50g Co(ClO4)2.xH2O
100g WO3 (4N purity)
100g MoO3 (3N purity)
100g Ca(IO3)2
Somewhat more exotic chemicals, especially the first one. I now have tellurites and tellurates, allowing me to investigate the differences between
these.

Password recovery really doesn't work on here.. I wrote earlier as Notthatkindofdoc.
As pointed out in a thread in organic chemistry, the "borneol" supplied from the indian eBay seller is Camphor. So don't buy from them unless you want
camphor
Reduction of camphor seems to be a bit of an experimental route (apparently MVP reduction with aluminium isopropoxide is possible, but hard to find a
description of the process) or require some harder to find chemicals. So for me at least it is better to make another attempt at obtaining the borneol
from a supplier.
So.. I have tried alibaba for the first time. It seems to be a reputable seller, and i have a package on the way with tracking number and everything.
The remaining issues are confirming the actual contents, clearing customs, and the fact that it was by no means cheap. The minimum order size was 1kg,
which should be sufficient for a few lifetimes worth as a catalyst. I'll let you know if it meets expectations

So today I got a 1kg bag in the mail from China, which is supposed to be borneol. It was not cheap, but my first experience buying from alibaba was
not bad if I got the actual product i ordered. It does look different from the indian e-bay stuff marketed as borneol, but containing camphor. The
smell is similar, but not identical, it is more fruity in character?
It would be nice to test it and see what I have, but I lack very sophisticated means of doing so. The biggest difference I could find which is
somewhat easily measured is the melting and boiling points. Borneol is supposed to melt at 208 and boil at 213C, while for camphor it is supposed to
be 175-177 and 209C respectively.
When I heat these up they both fume quite a lot, seemingly sublimating and recrystallizing on the colder part of the container. With simultaneous
heating the assumed camphor never really properly melts, but softens up, and changes to whiteish blobs. This was delivered as largeish flakes, with
small glinting specks as a prominent visual feature. The borneol is smaller crystals, with much larger single crystals, and a clearer crystalline
structure.
The assumed borneol does melt, and seems to go almost straight to boiling. Upon inserting my crappy thermometer in the boiling mixture, it reads 219C,
which is 6 degrees above the boiling point of borneol and 10 degrees above the boiling point of camphor. White crystals form rather aggressively on my
thermometer, which might possibly increase the heat transfer? The measured temperature might just simply be a result of a bad thermometer.
First pic camphor, second pic borneol third pic borneol sublimated onto thermometer.
So what do you guys think? Is it legit? Are there any proper tests I could do?

How about adding some bisulfite solution?
I couldn't find the confirmation that this is also true for camphor, but aldehydes and ketones are known for creating adducts with sodium bisulfite.

Any day that three packages arrive from Poland is a good day.
I got some lovely "Fe2O3" with the distinct aroma of number fifteen.

All three from Onyxmet and from the same order.
The multiplicity of packages was insurance against sensitive stuff having hiccups at the border. And it did not increase postage in this case.

So, have you tried Nurdrage's synthesis of Na(s) yet? If so, how did it work out?

Onyx Met is preparing an order for me but something is troubling me.
The messages are signed Tom
If I pay by bank transfer the name is Christian.
If I pay by Paypal the name is Fred and the domain is bellsouth - far from Poland.
If you recently ordered (and received) something from them could you let me know if you went through a similar ordeal ?
I cant remember who I paid to last summer. What I do remember is Keten taking my money and playing dumb by mail (when he answered at all) so I'm a
little bit paranoid.

Yes, I paid by paypal and had a similar situation. However, all was well as my order turned up as expected. It does seem a bit unusual though...

I think it is a business tax dodge. Where possible he has his international clients pay his international suppliers directly. Makes a certain
cunning sense.

I got some ammonium molybdate in the mail a few weeks ago. The envelope it came in was open when I checked the mail, which was somewhat alarming (!).
I opened it and found a bottle of white crystalline solid, with no label (!!). At first I assumed the glue on the envelope had failed solely due to
the cold, but on closer inspection, the glue had a white crystalline solid embedded in it, compromising its stick (!!!). Spot tests (NaOH; acidic
phosphate) confirmed that both the bottle's contents and the material in the envelope glue were ammonium molybdate, but the episode was sort of a
headache and I didn't hear back when I mentioned it to the eBay vendor responsible.

Weehee !
My order from OnyxMet arrived today.
All my worries were for nothing: the package was actually sent 2 days before payment ! All I can say is that builds a lot of trust.
There is one item missing but I'm sure we'll sort it out.
I am very pleased with the superfine synthetic diamonds. I have mentioned plans with diamonds to some members: soon !
I also got an interesting small vial of Galinstan 80 and all three colors of Strontium Aluminate that I'll use to dope some of the adultered
phosphorescent pigments from eBay.
