Aluminium powder also is quite interesting for small-scale experiments. With KBrO3 and S it makes a nice mix, but be careful with that. KBrO3/fuel mixes are at least as sensitive as KClO3/fuel mixes, but for small scale experiments (prepare less than 100 mg in one batch) it can be fun for demo purposes.

I bought the potassium bromide because it is an efficient oxidizer for making bromine and potassium permanganate is quite precious to me as it is quite difficult to get :(

I have never bought sodium before, but I have heard many good things about GalliumSource.com. They sell 140 grams for $89 + shipping which would be about $32 for 50 grams. But you can't forget about the dang shipping cost. $10 for shipping plus a hazmat fee of about $35 (although I think GalliumSource pays that for you already if I'm not mistaken). Their minimum size is 140 grams though... I've never bought sodium before though, so I am not exactly sure what a 'fair' price is.

Mood: DEAD (diethyl azodicarboxylate)

[*] posted on 23-3-2013 at 13:20


I just made a run to the local hardware store to get some potassium nitrate stump remover. Every other time I go there when I don't need it, I see it, but when I do need it, it is nowhere to be found. :( Anyway, while I was there, I couldn't help but get some other chemicals.

Guess what? They were having a sale on both drain cleaners and pool chemicals. What are the chances of that... Normally I can get 1 liter of crystal clear ~93% sulfuric acid as a drain cleaner for about $8 a bottle, but now it is only $2.50 per bottle/liter. I couldn't help myself... :D

3 liters of sulfuric acid - $7.50
2 pounds of 99% copper sulfate (for drains) - $7.00
2 gallons of 12.5% bleach - ~$5.00
1 pound of calcium hypochlorite - $2.00
Some phenol red indicator - $1.00

I love shopping for chemicals. It's actually pretty fun trying to figure out what chemicals are in which products. I think I might have to go back and get some more sulfuric acid before they sell out or get rid of it. They already got rid of the old brand I used to get, so I don't know how much longer they will carry this one. By the way, the sodium hypochlorite is light green/yellow. This is normal for concentrated bleach, is it not?

Those are very good prices. I recently purchased 2.5 liters of H2SO4 (96%) and 2.5 liters of HNO3 (70%) for EUR 60 (incl. shipping), making the price per liter well over EUR 10.

Conc. bleach indeed is pale green/yellow. This is due to the color of HOCl.

30g KOH x3 - to replace my dwindling stock of KOH

Mortar + pestle - to replace a broken mortar from months and months ago

250mL beaker - to replace a beaker broken a month or two ago

1000mL beaker - to replace a beaker broken two days ago

Carbon electrode, 1/4" x 4" rod - to use for electrochemistry, and to compare between battery-grade and this 'official' one

Glass tubing, 5mm x 12" (x4) - to use for ampouling, etc.


Ordered from HomeScienceTools. Total cost about $39, shipping (mentioned as 3-8 days) arrived on the 3rd day, incredibly fast! 10/10, would buy again.
Now if only I had money... :P

I purchased a single chemical. SImply could not resist it, because it is rare and maybe a single chance for me to get this:

50 grams of very hard to obtain TlNO3

Yes, now I finally have a thallium compound. Experiments with this will soon appear on my website ;) This element has an interesting redox chemistry and apparently also quite interesting coordination chemistry with halogens.

How much did that cost you?
The only source I could find was the sulfate, at $8.50 per gram (http://stores.intuitwebsites.com/beaglewebstore/-strse-2004/...)

I purchased the material here:

http://www.ebay.nl/itm/Thallous-nitrate-MB-99-9-Trace-Metals...

I ordered two of these bottles, because I had to pay a lot of fixed additional costs (postage appr. $25 plus customs and taxes appr. $40, regardless of buying one or two bottles). This guy has other thallium salts as well (e.g. thallic nitrate 4-hydrate), but I chose the product with the highest thallium weight per dollar. In the other compounds you have more nitrate and water per gram of material.
Altogether, this was not a cheap buy for me, but I decided to buy it because here in NL it is virtually impossible to find thallium compounds and this offer may disappear soon again.

You should have spun them a tale about how it's uppity attitudes such as theirs that are making this a difficult hobby to enjoy at times ;). Glad you found the carbide elsewhere though!

Nothing special, some sodium bromide (500 grams), glacial acetic acid (1000 mL) and a formaldehyde solution (1000 mL, 37%).

I'm saving money for a larger investment when it comes to lab equipment in general, so chemicals will unfortunately have to wait for some time. :(

I got 1 lb of tungsten powder! :)

The density of the powder is disappointing, however, fitting in about 47 mL. The density of the solid metal should be almost twice that.
