[pure-silver] Re: Kodak Special PX 3001paper

Cosmic radiation is only an issue with high speed films. Paper is so slow compared to film I wouldn't be concerned about it. Kodak stores high speed films deep underground in a salt mine near Batavia, NY to minimize the effects of radiation.
Life of paper on the shelf (room temp) is not more than 2.5 years and that is with RC. It is less with FB. Believe it or not, the ID improves life. At least w Kodak papers. Then fog begins to build up.

PS: NYS Riesling goes pretty good with souped Tmax film.

I now remember the rest of the conversation with the Ilford rep. He
mentioned that cosmic radiation contributed to the fogging of the paper, and 
film, and that this radiation easily passed through my freezer. He also
mentioned the savings in electricity would go towards buying fresh paper.
Years ago I acquired a photographer's studio at an estate sale. Among the
items was a freezer of film and paper. I had no idea how long the paper had 
been in the freezer. I ran the freezer for a couple of years until it
finally died. The paper then lived at cool dead freezer temp for about 6 or 
more years, before I tested the paper, and film with a step table. All the
RC paper was heavily fogged. I suspected developer was incorporated in the
emulsion. The fiber base paper is useable with great care. The biggest issue 
is the choice of developer and time of development. 1min. to 90sec. max
anything over the later time fogs the paper. The film fared better as I was 
able to print through the fog. The Ilford Delta 3200 was a loser. The film
is mostly long gone except for some 4x5 B&W, and Color stock. Some paper
still exist which I rarely but occasionally revisit when I'm printing a
print that does not have bright high lights. One of these days I will have
to deep six the freezer, and what remains inside. In the mean time I'm try
to use up my fresh stock so that it does not end up in the dead freezer.
There is a small amount of film in our small kitchen refrigerator freezer
section, and my wife has suggested I might think about cooking it for
dinner, and I counter with, it might be better if I soup it.

This is a "no win" question.   Options are have the paper go bad as the
natural age is used up.  If that happens the paper might be used for some
artsy stuff. Option two: Possible emulsion freezing and re-freezing issues, 

that you may never see.  I'll go with the later....
Please understand, it is always better to buy and use fresh paper and not 
buy huge quantities and freeze it.  However when you get a gem like old
Ektalure, which has been discontinued, there is no option.

Dave what are your thoughts on the moisture in the emulsion expanding when 
it freezes. I spoke with an Ilford Rep some years ago and he advised
against
refreezing because of the possible damage to the emulsion.
I have not gone the freezer route as energy to run the freezer is costly
living off the grid. In fact the last freezer I had ran 100% of the time
when the ambient air temp reached 95'which amounted to 5000 watts over 24
hours.

The paper he has is old and expired by at least 5 years.    If he tries
some

and it does not have fog or mottle it is still good.  I would keep it in
a
plastic bag and freeze it.  Allowing it to warm up for an hour before
using
it and re-freezing remainder immediately afterwards.
Kodak discontinued Ektalure about 6 or 7 years ago. It is an outstanding 
product with history going back almost 100 years.

And does this mean it will be on the market?  or is his an old box?

in the product so they might be sensitive to the change.   For example,
if a change was made that affected how the paper would  look in process
the users would be selected based on the different  chemistries they
used.   That means the sale reps would really need  to know their
customer base.   Usually all professional  photographers.   They would
test the material and Kodak research  staff would interview them.

I'm very curious how one gets on a list to try out their new products.

PX just means experimental.  FX is "film experiment" PX is "paper
experiment".   The 3001 just means that was the next number
available



from corporate for test projects. It is a more recent   number. Open
the box (in total dark, no safelights) and see if there is a stuffer 
sheet inside.  It will tell you how to  process  the paper and
hopefully how to expose it.  I don't  remember if 3001  was one of
mine



or not.

Dave

   It's nice to have really authoritative information available  to
the list. Thank you Dave.
