Came back from Home Depot, picked up some copper sulphate among other things.
They also had a drain cleaner which said "WARNING: HYDROGEN PEROXIDE" and none of the usual lye warnings. Very interesting- has anyone ever seen this? I didn't buy it though, and I forgot the name :P

I purchased some LiH. This is amazing stuff. It forms a white powder, so very light that simply opening the bottle already gives fine dust in the air, which is EXTREMELY irritating. The dust is odorless, but it makes you caugh incredibly, even when the amount is so low that you don't even see it.
I can imagine that it is irritating. LiH reacts with water to H2 and LiOH and the latter is a strong base, which is extremely irritating for the throat when inhaled.
LiH reacts violently with water, giving H2 and a fair amount of heat. It also dissolves in methanol and ethanol, giving methoxide and ethoxide in solution. That is why I purchased this stuff.

This was a one-time opportunity. I had this from Onyxmet in Poland, but the company doesn't have it anymore.

If there is significant demand for CS2 here it can be obtained from ReagentStore.com (South Korea based) for $60/kg. Split several ways thats not much. 200 mL four ways, 100 mL eight ways?

How long have you been hiding that gem of a supplier?
What a fantastic range. Of course some of it is pricey, but if you need something specific...

They are pretty well known. I want to say the either are or were an eBay seller. There are quite a few others like them that sell chemicals online with a sales front seemingly oriented to one-off clientele.

I think ReagentStore is the only international one that I can think of, besides onyxmet, of course, which happens to be another wonderful source of many things not easily attainable to the amateur. Check them out. I have used them quite a bit for various things here and there.

VWR High-Density Polyethylene Wide Mouth Bottles, 250mL, 72 count

This is what I will be using to package the Sodium Borohydride (NaBH4). I have messaged a couple of people about free samples already, but if you are interested, shoot me a U2U and we can work out a deal for purchase. I will be posting an official sales thread, but not until I get feedback so that I can address any potential issues.

I just bought a large amount of NaOH for making soap. The chemical is slightly interesting at best. It is food grade and uniform beads without dust. The nice part is the price, about one dollar per kilogram after tax. The bad part is driving 200 miles to get it. I also got citric acid for my water softener.

Concentrated nitric acid, 30% H2O2, 28% ammonia, and a bunch of lantern carbon/zinc batteries for the MnO2 and graphite rods. Also, some sulfuric acid drain cleaner. Apparently, on 47th St. in Manhattan, there are stores that sell all sorts of metal refining chemicals OTC.
