Silver Gelatin

Matt Clara - 24 May 2005 16:02 GMT So, having combed the archives for all of three minutes, I've come to the realization that I'm _already_ making silver gelatin prints with Ilford papers. I am so cool, and I didn't even know it ;-) It looks like all the rage these days is to buy _liquid_ silver gelatin and paint it onto other substrates, such as homemade paper, ceramics, or whatever won't fall apart or be altered by the chemicals at hand, and make prints on those surfaces.
Where do you buy your liquid silver gelatin? I've found this page: http://www.rockaloid.com/prices.html#liquid $56 seems a tad pricey, but then, I don't really know.
Thanks.

Silver-gelatin seems to be a description invented by gallery owners to distinguish "plain vanila" prints from those made by more exotic methods like Platinum or Carbon. Being a gallery term its slightly high-flown. I think all the liquid emulsion sold is made by Kentmere in England. Kentmere is a very old company who make some very good papers and specialty products. There are several ways of printing on special materials. One, of course, is the use of a coatable emulsion but one can also print using photolithography or by using silk screen using a gelatin or other colloid to make the mask. There are also methods of coating something like Carbon tissue material with an appropriate pigment onto a ceramic and firing it. The pigment then becomes imbedded in the glaze while the colloid is burned away. I no longer remember the name of this method.

Of course the color it produces depends on the paper or film one is toning but, in general, its a reddish brown. Uranium toner was evidently quite popular in the 1930's probably for the color it produced. I think I posted the formula for Kodak's Uranium toner to this group not long ago. I don't suggest it as a practical toner. First of all, Uranium Nitrate is likely very difficult to obtain but also its not a protective toner. Most toners using a Ferricyanide bleach, like Copper and Iron-blue toners, produce images which are less stable than the original silver.

No Plutonium but there is a Uranium toner, once fairly popular. Uranium can also be used as a mordant for dye toning. A typical Uranium toner is Kodak T-9:
Kodak T-9 Uranium Toner for Transparencies and Motion Picture Prints.
Uranium (Uranyl) Nitrate 2.5 grams Potassium Oxalate 2.5 grams Potassium ferricyanide 1.0 gram Ammonium alum 6.0 grams Hydrochloric acid, 10% solution 5.0 ml Water to make 1.0 liter
Dissolve chemicals in order given. The solution should be perfectly clear and light yellow in color. It is light sensitive and should be stored in the dark. The maximum effect is produced in about 10 minutes the tone passing throught brown to red in this time. There is likely a variation of this for prints but I was unable to find one.
I don't know for certain about the permanence of Uranium toned film or prints but, in general toners of this type, such as Iron Blue toner or Copper toner, that use a ferricyanide bleach to replace the image silver with another metal, produce images which are less permenent than the original Silver image. They are not protectants as is sulfide or Selenium toner For all I know there may indeed be a way of toning with Plutonium:-)

I thought Fiesta Ware was a problem only where large quantities of it were kept, such as the manufacturer's factory or storage warehouse. I think it was the vats of glazing material, before it was applied to individual pieces, that were the real danger to people spending workday after workday close to quantities of the glaze.
It's similar to the problem of cadmium in photosensitive material. The sheets of paper containing minute amounts of cadmium are (or were...) no problem to darkroom workers or photo buyers, but the workers in the manufacturing plant had to hang around large amounts of it for a long time. I think yellow automotive paint used to contain cadmium - the police cruisers in Toronto used to be bright yellow until the environmental/working conditions legislation came into existence.
So if I get prostat cancer can I just strap a Fiesta teacup on ... ??

As mentioned previously, Fiesta glaze dissolves in acid - like OJ or lemon juice on asparagus, say - and radionucleotides hang around in the body just like any other heavy metal -- of which Fiesta wear glaze was also full of.

I realize this is severely OT, so I'll be brief, but I can't resist ...
Recently I've been researching a device originally from France. Its name is so hilariously wonderful I can't hold myself back (and I swear I'm not making this up...) -- the Prostatron. Its probe (probe...) is electronically cooled and radiates microwave. It is controlled by software now specified as version 3. The Prostatron is vastly preferable to certain surgical procedures. So maybe digital isn't so bad after all.

All of the ones I know of use heat. The most common one is a, well, long oblong shape with a line cord sprouting from one end. It is applied to the patient in a manner such that the patient has the line cord sprouting from his end and the cord is plugged into the 120/220V outlet.
Yours sounds like a much more modern digital diathermic digit.
Statistically the most effective treatment for prostatitis is no treatment at all.
Now -- how do we get this back on topic:
Will I still be able to buy film in twenty years? What is a good developer for Tri-X? Does anyone have a Durst "dadupa" lens adapter? Everybody is a rip-off artist except me - Wanna buy a Benz-Gant, only $90?

Tri-X works well with a number of developers. For normal development D-76 stock or diluted 1:1 gives good results. For pushing try T-Max, Xtol, or Microphen. Tri-X needs a long fixing time similar to T-Max films. Can't help with the other stuff. As far as what films will be available in 20 years, my crystal ball (made of pure silver nitrate) has been tied up looking at the commodities markets and horse races. Its been clouding up lately and complaining of headaches.

Good point. I haven't actually had treatment in either mode.
But the conventional method was/is to undergo knife-style surgery. It's called TURP (Trans-Urethral Resection of the Prostate). They refer to it as the 'gold standard' of this sort of thing, because it's been done a lot and works quite predictably. But it has all the drawbacks of regular surgery, like a significant recovery time.
The microwave devices focus heat into the prostate from the probe within the urethra. No cutting, just a bit of cooking. The probe is electronically cooled so the urethra and immediate environs (important!) are not cooked. Recovery time is reputedly quite short.
In both cases there is a real but small chance of sexual dysfunction afterwards. Hence the medical term, "watchful waiting". In other words, wait as long as possible before doing anything because you might lose sexual function, and wouldn't it be great if it turned out you were so old before you really, really, really needed it you didn't function anyway, or maybe even were dead by then.
My comment about the microwave techniques being preferable was not based on personal experience, only investigation. There are horror stories about any of the techniques, I believe. I've also seen remarks online from patients who have had brilliantly wonderful resolutions with all current methods.
The Prostatron and its ilk are designed to treat a condition called BPH (Benign Prostate Hypertrophy). This is not cancer, and is different from prostatitis. Supposedly 80 per cent of men get BPH by the age of 80. It's a hell of a piss-off (and that's a pun, intended...). It also interrupts one's sleep, truly one of the universe's little ways of laughing behind our back. ISR - interrupted sleep rage??
Well, you asked. I still think Prostatron is a funny 'word'.

How about watch dials? Several years back Readers Digest reported a story of a gentleman inclined to experiment with radioactive materials, somehow he managed to concentrate the luminous material found on some types of analog dials. When the authorities finally caught on to what he was doing in his backyard shed (Trying to build a reactor) they ascertained that the radioactive levels were several hundred times what was considered a truly dangerous dose of radiation.

A few years ago there was an article in the New Yorker Magazine about a fellow who made art from radioactive materials. He had some sort of degree that qualified him and worked in cooperation with the atomic energy regulatory agency. Apparently his art was safe. Personally, I don't get it, I like silver and horrible chemicals like sodium thiosulfate, yumm, dangerous.

Orignally, glow-in-the-dark watch and clock dials contained some Radium to energize the flourescent material. Most of the dial painting was done at one of several factories run by a company called The Radium Dial Co. Hundreds of girls were employed at what were then good wages to paint the dials. They used small brushes and shaped the brushes by licking them. They got large doses of Radium which eventually caused a very high cancer rate and killed a lot of them. The factory operated from the late 1920's. The first law suit over Radium poisoning and exposure to radioactivity came in 1938. Few of the victims sued. It turned out the company knew all along they were putting the girls in mortal danger but lied about it. Radium dials were still being made after WW-2. I don't know the date at which they were discontinued. Current glow-in-the-dark dials do not really glow on their own. Most are energized by the UV content of the room light and continue to phosphores at a decreasing rate in the dark. Eventually they become invisible. A Google search for "radium dials" will find various versions of the above story.

Radioactive watch dials are still [?] available, but they use Tritium. If the watch dial has a 'T' or two at the 6 O'clock position then there is tritium in the glo-paint. Tritium has a short half-life and the glow only lasts for 12 years or so.

jun205 from Lloyd Erlick,
There is a famous photograph of workers sitting around a long, broad table doing this (or similar work). Along the center of the table are large bowls or vats that appear in the image to be brightly radiating light. They are actually full of radioactive material, of course. One worker is leaning over one vat, to reach another beyond it with her brush (all the workers are women). Her whole upper body is lost in a bright aura above the container.
I forget whose work this was. Hine or Riis, perhaps?
Somehow it's all the worse to consider that the employer knew of the danger to the workers. Somewhere there are heirs to the money made this way. Sounds like a great screenplay...

To add injury to insult, the women doing the painting would point the tip of the brush by stroking it against their tongue
> Somehow it's all the worse to consider that > the employer knew of the danger to the > workers. From what I have read the answer is no. That the radium was dangerous to handle was well known. The paint was considered harmless as the radium content was very low. At the time small amounts of radium were even considered beneficial to health - boosted the immune system and all that.
You might think folks are smarter these days:

But they aren't.
> Somewhere there are heirs to the money made this way. No money was made. The owner of the enterprise was left with a lead casket containing a vial of radium at the end of WWII. Rather than mail it back to Oak Ridge he built it into the brick backyard barbecue of his little post war tract house: "I need to get rid of this stuff -- quick. Where is a safe place?"
The radium was discovered 20 (??) years ago when the barbecue was knocked down.
In the end the heirs to what was left weren't relatives, and they wished they weren't heirs.

"To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public."--Theodore Roosevelt, May 7, 1918

Cf. companies or institutions that were founded on money made in the slave trade: Aetna Insurance, Brown University and Harvard Law School.
Or those with close ties to the Nazis: Bayer and IBM, to name just two.
 Signature When someone claims that the Government is monitoring their thoughts, we call them paranoid or crazy. I prefer to think of such people as just slightly ahead of their time.

I remember seeing a photograph made on a white porcelain tile. The subject was a bathroom fixture.

Decorated ceramic tile is in with the modern Yuppie crowd.

See http://www.rockaloid.com/ for complete information. There are on-line instructions. Rockland makes or sells two types of emulsion, a plain one and a VC one. The plain one specifies an "amber" safelight (probably a Wratten OC) the VC a red safelight. The red light will be safe for both. These are both very slow emulsions. Surface prep and subbing are important. Some people have had problems with the emulsion coming off during development. I suspect Rockland can be helpful with specific applications.
