I found these sitting in the back of my chem supplier and they forgot they even had them. I had to go ahead and get them. $60 for both. I suppose I'm
pretty set for nitrates for a good while.

Thats cool, i recently moved and left behind aprox 25kg of NaNO3 by accident, and going to pick it up would be a pain in the arse ![:(](./images/smilies/sad.gif)
on a more positive note 1kg of KI arrived a couple of days ago for £38 which i just had to have at that price ![:)](./images/smilies/smile.gif)

i saw these cool looking acid bottles online. I think they are from the 40's. I bought one for nitric acid.

Few beakers. As well as 1000 g of Molybdenum oxide, 250 g of NaI (I use NaI instead of KI as I get more I- for the same price!)

Bought 150g of Nickel from place that supply plating companies, ended up being cheaper than buying from China. Problem is I haven't had time to do
zilch with it =/

100ml of 50% hexafluorozirconic acid in water was given to me, not sure what to do with it really... I accepted it without really thinking.

Vanadium pentoxide -- 100g all the way from Bulgaria.
It's been on the must get list for a while. When I saw it at a good price I couldn't think of an excuse.

Nice! Vanadium pentoxide is one chemical I have always wanted (no vanadium compounds) but never gotten around to buying cheaply or easily.

I got some heavy water FOR FREE!!!
I grabbed 3 empty D2O bottles from the trash at the university. Each one had a few drops left in it.
I suspect its mostly regular H2O absorbed from the air by a tiny bit of D2O stuck to the glass. Is there any way to test the ratio? The fact its
hygroscopic is fascinating.

Cody does an analysis on his D2O that he had five days to produce. Some interesting findings especially with respect to the NaOH he was using. Of
course he had access to some technical equipment for this one.
You might look up his earlier experiments where he makes D2O and performs a variety of experiments on it. A density measurement springs to mind but
you might have difficulty with such a small volume and it would also be affected significantly by whatever other contaminants are present (or
introduced).
Have fun!

The local brew etc. store has packets of something called "PBW" from Five Star Chemicals & Supply, Inc. The label claims it contains sodium
metasilicate and sodium carbonate; the MSDS says it's sodium silicate and/or "silicates, phosphates, and surfactants". This is the only sodium
silicate I've seen in a brick and mortar store since the old-fashioned pharmacy stopped carrying it. It wasn't expensive so I got a pack but I haven't
come up with a good way to separate the silicate from the carbonate and others. I wonder if I can grow a chemical garden in it?

Acquired this today. The silver oxide and iodate bottles are unopened but appear to be quite old. The chems inside look as they should.

The silver oxide and silver iodate are very nice. Those are worth quite a lot of money.

Thats what i was thinking. I didn't have any silver compounds because they are so expensive. I was fortunate to get these for a great price and they
are 4 oz bottles. I dont know what they are worth but im sure I got a good deal.

Especially the silver oxide is very interesting. This allows you to make nearly any silver salt in aqueous solution, by adding the oxide to a small
amount of dilute acid. This works especially well for nitrates, perchlorates and acetates.

For my element collection I purchased an ampoule of 10 grams of 99.9999% arsenic and a piece of 2.7 grams of 99.9% beryllium, disk shaped. Have a look
at Onyxmet's website for these samples, he just received very affordable samples of Be and As, very nice and shiny samples of very pure material.

Darrant Chemicals - anyone had any dealings with them?
I ordered some bits on the 20th Sept, nothing dodgy or nasty, but have had nothing back. They took the cash immediately, but then squat. No delivery,
no emails, no phone calls and if you try to call them it just rings and rings. Found this:
https://www.yell.com/biz/darrant-chemicals-lincoln-8313838/
...which does not fill me with confidence.
I'll give it another few days but then, assuming I have still got nothing, I may have to write it off. Annoying. I'd not recommend these cowboys at
all.
I used a credit card...anyone know my rights on getting a refund etc?
Cheers
Angel.

If you used a credit card, then most likely you can reclaim the money through the credit card company. This is how things work in NL, don't know the
situation in the UK.

Fisher-Johns Melting Point Apparatus
Not a chemical, but useful to evaluate chemicals. I bought this in an ebay auction for USD15 (plus USD 16 shipping!. Only thing wrong was that the
thermometer was missing (the seller said broken - same difference), and the ferrule or bushing where the thermometer bulb enters the heating block is
badly corroded. That is a type K thermocouple I have inserted into the thermometer port. The unit is not calibrated yet. I may tap a hole into the
heating block to mount the thermocouple.
I've searched for a manual but the only thing I can find are from outfits and sell pdf's.
Picture attached.
