RE: Source for Uranium Nitrate


Cor, aren't there differences in strength? Like between salad vinegar and glacial acetic acid? I certainly hope so.... I've had that package of uranyl nitrate in my cellar all these years, oops ! It came in a metal container packed in something like mica -- but over the years the cover & most of the mica disappeared. Oops ????

Does anyone remember--- dare I mention the name without some avenging angel sweeping out of the shadows to denounce me -- Jewellia? She did uranium printing, apparently -- and though memory weakens by the minute, I think some of the prints were beautiful.

But if you don't tell us what "I will not..oude koeien uit de
sloot halen....(dutch verb).." means, I'm going to correct you.
(Like don't you mean "proverb," not "verb"?) NOW, fella, what does it MEAN? ("Don't teach your grandmother to suck eggs?" Or...????) It *sounds* -- or make that *looks* -- wonderful

(But please, no nonsense about my Dutch.)

Dick,

I am realy surprised by your reply...I will not..oude koeien uit de

I do think that the stuff should NOT be treated lightly:

http://en.wikipedia.org/wiki/Uranyl_nitrate

Health and environmental issues

Uranyl nitrate is an oxidizing and highly toxic compound and should not
be ingested; it causes severe renal insufficiency and acute tubular
necrosis and is a lymphocyte mitogen. Target organs include the kidneys,
liver, lungs and brain. It also represents a severe fire and explosion
risk when heated or subjected to shock in contact with oxidizable
substances.


http://physchem.ox.ac.uk/MSDS/UR/uranium_nitrate.html

Toxicology

     Toxic by inhalation or ingestion. Should be treated as a potential
carcinogen. May cause mutagenic or teratogenic effects. Danger of
cumulative
effects. Caustic, corrosive.

Yyes, yes, ofcourse Mark will not eat it, but nevertheless...


Best,

Cor

Mark,

Gonna be really hard to get. It now needs to be shipped as a

radioactive

substance in approved lead lined containers and all of that crap. I am
not even sure if can go on airplanes. We quit shipping it several

years

ago. Cole Parmer used to carry it but they quit when the shipping went
sky-high.

You can see they discontinued it as well.

I think it is all a big bunch of hooey. It is in fact slightly
radioactive but only slightly. All the good bomb making stuff has
already been taken out, and that makes logical sense. I have my own
special horde of it, about 300 gms left that we can't sell, and I once
showed the bottle  to some students visiting and their professor

freaked

and virtually ran out of the room. Like most airport security, it's

all

show.

I am seeking a good source for purchasing Uranium Nitrate for

creating

a Uranium toner solution.  So far I have had trouble finding a
source.  PF doesn't carry this item and I would suspect that

hazardous

considerations may be a factor or scarcity.

Specific Application:  Perhaps there is an alternative toner with
similar effects (realizing that considerable differences exist with
formulas and applications).  My initial use would be with
silver-gelatin and then moving to eventual non-silver application.

It

is said by Robert Schramm, in his excellent but short article
regarding Uranium Toning  www.unblinkingeye.com
<http://unblinkingeye.com/Articles/Uranium/uranium.html>  to produce
red-brown tones on silver prints and blue, green and red tones on
platinum prints.   If one reads the article, figure #1 image

presents

a similar effect that I would like to replicate, as much as

possible,

/girl aside!/  I would be inclined to use Bergger VC NB paper or
Silver Supreme paper for a given motive that I have photographed.
Then figure #2 toning would be of future interest in other
applications.  (effects are considerably different on platinum vs.
silver as can be seen)

Anyone's recommendations or suggestions would be greatly appreciated
to this (less experienced) practitioner.  I imagine that Tim

Rudman's

book, /The Photographer's Toning Book/, would be a good source to
review as well!

Thanks in advance,
Mark Booth
