    Deniz,

    Strictly speaking AZO isn't POP nor could it be used as POP since it requires development of the latent image and is not self masking.

    Don, I remember one day leaving a sheet of AZO on my kitchen counter, when I came back after some time, maybe a day or two, the paper was completely fogged. I believe that if you put a negative on top of the paper, you can fog and image onto it. It will not have dark dmax but it will print.

    If you have a look in the Experimental Galley, you'll find some prints by Lasse Melberg (sp?). He's using Sodium Nitrite (not nitrate) on contact printing papers to render them useful for POP. I've been meaning to try it when I find some of that chem.

    Christian,

    Any silver gelatin paper will darken upon exposure to light but that doesn't make it a POP paper.

    Deniz and Mateo are right, Lasse is modifying Azo to become a POP paper, but that is a modification and not the intended use of the paper. Someone selling it should know what it is, otherwise how do we know he has taken good care of it. For all we know this guy is storing the paper right above the room heater.

    I have no plans to use Azo, but if I did, I would get it from Michael, not only do you help keep your favorite paper alive, but you get the wealth of knowledge and a guarantee from Michael. YOu can bet if there is something wrong with the paper Michael will fix it. I am not so sure about this guy on e bay, I mean, if he does not know what azo is, how is he supposed to know if something is wrong with the paper or not..... no?

    All right I didn't know that every paper will darken upon exposure. I thought that AZO being silver chloride...

    I just checked albumen works and it says that POP paper is gelatin silver chloride with an excess of silver nitrate.

    I guess that explains my confusion and clears my confusion.

    Which is what Lasse is doing, you can place Azo in a Silver nitrate bath and make it POP, but it is not inherently so...

    The market for Azo is miniscule at best. If people do not support Michael and Paula and splinter the market, then noone will have enough volume to run the next master roll

    I think that competition is a distant second. The best thing for the consumer, first and foremost, is for the product to be available. Michael and Paula have done a good job of ensuring that Azo remains available for now and I prefer to support them because of it.

    Cheers,
