    We can make our own platinum papers. I was wondering if this can be done with Azo as well? I'm no chemist so am not sure. Just curious if this is feasable should azo production from Kodak finally dry up.

    Are you nuts??!#@?!#? Just Kidding.. I think it would be a ton easier to buy a bunch of it to stockpile... this stuff lasts for years if stored in decent conditions...

    Do you just want paper? In the "Darkroom cookbook" I think he describes how to make your own paper. I just skipped it. Figure I can always go back if it ever becomes an issue-)

    Silver chloride emulsions are the basis for a few alt printing methods, like salted paper or Kallitypes. I am ignorant in the Azo production method but I imagine the paper must have some kind of sensitizer to allow it to be printed with a "regular" light instead of a UV light.
    If you want to try something similar and much cheaper than pt/pd try kallitypes, they are beautiful when done well.

    Since Michael Smith and Paula Chamlee have committed to buying whatever quantity of Azo it takes to keep it in production, I'm sure that we'll at least have plenty of warning should it ever be taken out of the lineup. At that point I'll buy a lifetime supply.

    Since Michael and Paula have made such a huge financial commitment to keeping Azo around it's very important that we who use it support them. If you're going to use Azo, PLEASE buy it from them. Their price might be a few dollars higher than someone else's (although they're cheaper than Calumet) but their price is a whole lot cheaper than what you'll have to spend if Kodak discontinues it. Also, they are the only source of Grade 3 Azo in 100 sheet boxes, and 500 sheets is a pretty stiff whack to my bank account.

    Hello:

    Making photo paper is a fiendishly exacting process, successful only with very precise machinery- the layers must be fractions of a thousandth of an inch or the densites will be all wonky- and VERY expensive: millions.

    Platinum paper is easy to make as it involves only one layer and one solution: silver gelatin paper requires many layers, not to mention aging the gelatin and silver chloride.THEN, THEN all of this must be done in total darkness, whereas PT/Pd can be applied in reasonably bright yellow light, as it is sensitive only to UV, where silver salts are sensitive to more wavelengths of light.

    This means the sensitizers must be added, balanced, then aged etc etc.

    When Kodak builds a plant to make paper the investment is over 500 million dollars!

    This reminds me of what Richard Branson answered when asked how to become a millionaire: "get a billion dollars then start an airline".

    Buy Azo from Micheal and Paula and each time you get a good print say "Thank you Michael and Paula AND Kodak".

    Well, the nice update in "Contact Printing" seems to have vanished. Wonder where it went. But, here is an ancient thread that seems begging for an answer and it came up in my search.

    Yes Sean, you can make Azo, or at least a fair work alike. It all depends on how hard you want to work for it.

    Now tell me where you guys hid that thread. Either it was deleted or you have a very poor search engine.

    BTW, I poured a specimen, as you requested on my 'P' key and the key melted. What does that mean? Then a window came up that said "Un*^^&# Error". My computer has hiccups now.

    Thanks.

    Wasn't it recently revealed that other sources besides Michael and Paula had made the last large orders of AZO and pretty much finished off Kodak's supply? I'm not so sure its going to be available for as long as some people think. Its already been taken out of the lineup and each sheet used is a countdown to the end. I thought about buying a box when I was in B+H last month in case I ever get into LF but then I figured whats the point?

    David, thanks but no. There was a thread started which updated us about the work of Michael and Paula re- Azo. It was in the contact printing section and seems to have vanished.

    A search did not reveal the recently started thread. Since I am old and prone to memory lapses, and seeing no information about deleted or moved threads, I immediately looked into my meds, what I was drinking and whether I was going insane.

    Since these don't 'seem' to be applicable, then I assume it must be one of you guys playing slight of hand. Of course, something new may be afoot, but since I just got new glasses 2 weeks ago, I really am not sure what it could be.

    Thanks.
