Boron Anyone?
Shopping aorund for some amorphous boron, for an element collection, and for some exotic thermite and intermetallic reactions I found the following
sources:
SkyLighter 1 oz $47.50 ($1.67/g)
eBay vendors:
50 g $38.20 ($0.76/g)
85.5 g $59.44 ($0.70/g)
and stuff at sky high prices.
I was considering shelling out the $60 for the 3 oz on eBay when I found this:
Firefox-FX 1 lb $109 ($0.24/g)
five times as much at somewhat less than twice the cost (in addition the site says "while it lasts", suggesting a limited supply at this price).
Firefox-FX, btw, has very reasonable shipping charges.
But cheap as that is, comparatively, 16 oz of boron is a lot of boron, and I don't really want to sink that much into a boron supply, far more than I
expect to ever use.
So: I am sounding people out here to see if I can defray the cost of acquiring a pound of Firefox-FX boron.
I have three suggested pricing models:
a) If someone wants 8 oz of boron, I will split all costs for buying, tax, shipping and reshipping in half and provide them with half the boron (thus
cutting my cost back to what I was considering);
2) Element collectors special: $10 for 10 g in a plastic vial, shipping included (this is still cheaper than the Skylighter cost per gram);
3) $5 shipping fee, plus $0.50/g, 30 gram minimum. Thus 30 g is $20 ($0.67/g, better than the eBay prices) and any additional grams are $0.50 each (I
will weigh out any arbitrary amount).
If I get enough interest I will make the purchase. Please respond U2U with the subject line "Boron" indicating your preference. I will post a
follow-up based on responses received.

I have been amazed at the spread as well- We use it in hot igniters with Potassium nitrate, rather than the good old fashioned (heavy metal, shock
sensitive) Lead tetroxide/Silicon.
Got all we need for now, but that's a good price.
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

So far I have had only one person express interest (at the $20 level), but to make this work I need to get another $40 or so into the game.
So I have a new proposal: split it at cost any number of ways. That is - the boron is the same price I paid per gram plus actual shipping charges
only.
So $10 would get you something like 30 grams, $20 would get ~70 grams (I assume same shipping as 30 grams), and so on. I would ship as cheaply as
possible.
Things to do with boron: element display, extremely high temperature solid phase reaction with titanium (and other intermetallic reactions), exotic
boron thermites, making boron tribromide:

I can open it on Linux and OS X with Firefox and Chrome.
No, it cannot be uploaded - it is not a file. It is a view provided by an online app of Annales de chimie et de physique, V. 52, 1858, p. 89. It is
provided by Gallica, the Bibliothèque nationale de France on-line digital collection.
Try this:

and page to p. 89 with the navigation keys.

Consulting Fieser's 12 volumes, it appears that boron tribromide is an effective reagent for ether cleavage.

I now have four participants at the $20 level, so the deal is going forward. I estimate the total cost, when all shipping is done, each participant
gets 65 g.
I can still take a couple of element collectors ($10), which would be for 26 g (since shipping is a higher proportion of the amount).
I have placed the order, and so should be able to ship out after Nov. 8.

Careful careysub !
That sounds a bit like "Order Now for delivery before Christmas !"
Who would even want Boron for Christmas ?

I have boron, isolated for an element collection. I intend to do some more: I want a better-looking sample and I wouldn't mind crystallising it too.
Which means that I have a little surplus at the moment. I might try out some of those exotic thermites or reactions with Ti. Or, if any aussies want
a 10g sample in an ampoule for their element collection, send me a U2U.

The boron has arrived, and I am packing and shipping this weekend (if you have paid, or once payment is received). I will be U2U-ing as needed.

I have seen it noted on amateur astronomy forums where astro goods are sold/traded that invariably people are extraordinarily careful to describe
every little defect in the stuff they are offering, and that rip-offs are unknown (though there are some commercial vendors that have proven
iffy).
I think the same thing operates here - anyone who as any significant longevity on this site values their hobby, and their credibility in the (very
small) community highly, and are quite reliable on following through on their commitments when making a trade of any kind.
