This is more about my *first* chemical order.

I started home chemistry with a little lab in the garage, most of the chemicals found around the house or provided by my parents. I remember very clearly the first time I purchased my own chemicals with my own allowance, getting an 8-ounce bottle of sulfur powder from the local general store.

Many years later, I make the bittersweet announcement that that bottle has run out, the last few grams being converted into zinc sulfide.

Time to get more.

The scaredy cat in me has finally(after roughly two years) mustered up the courage to order a sample of elemental mercury.
Yes, I am a wuss.

The next challenge will be transferring it to my bottle of choice, without my usual lab and equipment(since it is at home), so outside.

100 grams. It was the smallest amount they would sell at that store. It's only 7,6ml, so it's not much anyway.

Yeah, from a drugstore... it's an 'old-fashioned' drugstore... unique in the country. It was quite a search to get it.

I bought aniline and my grandfather shocked me with an old bottle of carbon tetrachloride! It was given to him by a friend many years ago to clean finger prints off the windows in his house... The friend worked in some kind of print shop. He was going to chuck it in the trash and decided to ask me if I wanted it, it's only maybe 300ml but CCl4 nonetheless :D

I just ordered 200 mg of C60 (fullerene) from an eBay seller (it is not cheap, this sample cost me EUR 14.70). This is not intended for experiments, but as part of my element collection. I also want to make a sample of C60, dissolved in an organic solvent. Just a fraction of a mg gives a beautiful deep purple color. C60 is one of the allotropes of carbon, which does dissolve in ordinary solvents! When the material arrives, I will make pictures of it and show it here.


It is now almost 25 years since a low tech production technique using carbon arcs was developed, but fullerenes seemingly remain extremely hard to source. On-line vendors generally have the "contact us for a quote" model that indicates a non-starter for the small hobbyist.

Even on Alibaba most listings do not quote prices. I see one (Jindun Chemical) offering "C60" at $30-$100/gram with a one gram minimum. $100 for a gram of pure fullerene (I assume a mixture) is not too bad, it would make up about 400 mL of saturated solution in toluene.

Some technical stock from an online pottery store. I like buying carbonates, because it is easy to dissolve them into various acids, filter out the crap, and then crystallize. It is then easy to get the reasonably pure nitrate, chloride, sulfate, acetate, bromide, etc salts on demand, for very cheap. All quantities in pounds.

Cr2O3
Li2CO3
MgCO3
MnCO3
NiCO3
ZnO

Some other specialties from the same company, in the same order (All quantities in pounds.):
NaF
V2O5
CoSO4 (1/2 pound only)
TiO2

From another place, 3lbs of sodium metabisulfite, for a sulfur dioxide video.

And finally, some equipment: A new submersible pump for pumping ice water, a 1/4" NPT gate valve for the SO2 tank, some Nichrome 80, a new 2kVA variac for Christmas, and this which had some pretty decent stuff in it like dimethylglyoxime and lead acetate.

Oh, and a pound of tin metal ingots, a pound of bismuth, and a pound of 99.99% copper shot.

It's in my signature, but I'll put in a shameless plug... I maintain a public Google document of my current inventory here, as well as a wish list.

today I got 25g Se(ebay) and a cryocool CC-100 II immersion cooler(obviously not ebay).

graphite crucible, full face shield/respirator and 2x small UV shield quartz tubes(doped to block UV for aquarium, only 99¢ea) on the way.

have to say the Se came unsatisfactorily packed. non-padded USPS envelop, with a paper folded in half and taped on the border as an envelope, with a double ziplocked bag inside. seemed like a great way to send finely powdered selenium? any sharp object could have impaled in one side and out the other. it didn't really look like the bag inside the other was wrapped neatly, just kinda shoved in...

Not a reagent but I found this at an antique store. The woman sold it for 3$ and called it a "smoking lamp" fml. I don't even know what to use it for... Distilling or steam generating, I guess. Although I have better things to do both of those. Oh well! Score nonetheless :P

I ordered a few new chemicals, some of them really special:

10g CoF3 (expensive, but allows me to make small amounts of elemental F2, by heating this chemical)
100g C2Cl6 (did not yet have this, is cheap, just over EUR 4)
100g Ni(ClO4)2.6H2O (did not yet have this, is cheap, just over EUR 7)
10g WCl6 (expensive stuff, but VERY interesting, maybe allows me to make a blue gas, if this succeeds then pictures will follow on my website)
1g Eu2O3 (nice fluorescence sample)
10g Ho2O3 (interesting for doing lanthanide experiments)
20g PBr5 (very nice colorful sample for weird compounds collection, in glass ampoule)
20g As (very nice sample for element collection, in glass ampoule)

All together less than 300 grams, but really worth the money. Especially the CoF3, WCl6, PBr5 and As are very interesting to my opinion (and these also make up over 80% of the cost of this order).

Ok. I have to ask. How do you propose to store the F2? Or are you going to use it straight away for something?
These all seem really intriguing to me.

I do not store F2. I just want to see it (and make pictures of it) and try some things with it, like throwing Al-powder in it (which is supposed to give bright flashes of light).

The experiments are on a test tube scale, not more, I just ordered 10 grams (CoF3 is EXPENSIVE, appr. $25 per 10 grams!), so the amounts of F2 made will be small and the safety issues only are moderate.

:o The same shop also sells pure very finely powdered SO3 (in a glass ampoule, 70 ... 80 grams), but this is so corrosive and extreme that I let it go. It also is very expensive, appr. $150 for 75 grams or so.

That's what we used as a distillation flask in the old days before the advent of RBFs and ground glassware. I have one but never use it. ;)

Yes my high school used to have some kicking around also but we never used them (same as retorts, got one of those and have yet to use the darn thing!) More clutter to add to the shelves lol

MEK! I think I know of the store you speak of... But it always seems to depend on the area you are in.

Weird. Xylene is at one small local store. MEK I need to buy at a special local store or a lab supplier. I find it so strange that one Canadian Tire sells it vs others. I wonder what determining factors decide if or if not it will be in store.

Yea, I was wondering the same thing. I have seen all those reagents on the shelves at Canadian Tire at one point or another, but it's always changing, with no apparent pattern. I haven't seen MEK in a while though... Does anyone know why they seem to be slowly phasing it out?
