    Kozo-shi paper for pt/pd and cyanotype?

    Hi all, I'm interested in MM-1 or MM-2 Kozo-shi paper from Hiromi Paper (see link below). Is there anyone using this paper for making pt/pd and/or cyanotypes?

    Link: http://02a9443.netsolstores.com/mm-1kozo-shi.aspx

    Suggestion(s) for thin (but relatively strong) translucent/semi-translucent paper suitable for iron processes will be highly appreciated.

    Thanks in advance,
    Loris.

    I bought a sample book from Hiromi and tested the wet strength and acidity of about every paper they carry. Both of these had decent wet strength and neutral acidity. Might be worth a try. The MM-2 is quite a bit heavier and a more neutral white base. If you don't want to risk anything, just buy the Kozo from Bostick and Sullivan. Their paper prints well and has similar texture.
    I just want to feel nostalgic like I used to.

    Thanks Clay!

    I'm more interested in MM-2 right now. I can use slightly more weight.

    The B&S paper sounds very Masa-like according to description and I have plenty of Masa on hands. Can you compare Kozo-shi to Masa? (If you have experience with Masa that is...) Also, B&S's paper is listed as being 50gsm, that's more than I want...

    Regards,
    Loris.

    The B&S paper actually is a lot nicer than any Masa I have ever used. It is a true Kozo paper and is slightly acidic, which makes it very friendly for pt/pd and cyanotype. I also want to make clear that all I did with the sample book from Hiromi was test the pH and soak a small piece of the various papers for 10 minutes to test their wet strength. The vast majority of the ones I tested are not suitable for photographic printing, and most fell apart like Kleenex after being soaked. But the MM-2 looked promising from what I could tell.

    Thanks much, I'll see if they're willing to send a couple of small sheets for testing before placing a relatively large scale order... I do really want to be able to print on thin japanese paper for making pt/pd (or cyanotye) chine-collé's or backing the prints with gold leaf.

    BTW, I'm not sure if acidic paper is better than neutral paper for iron processes -> not that you're saying that but it sounds so... My understanding is that as long as everything else is kept equal/constant, there should be no difference between the results from acidic paper and neutral paper.

    Regards & thanks again,
    Loris.

    Neutral is fine, to be sure, but the richest single coat paper I have ever used was super acidic, and using it allowed me to effortlessly produce very nice prints. Unfortunately, I have about twenty sheets of it left :^(

    Are both Kozo papers from B&S suitable for pt/pd?

    Clay,
    I just received some B&S Kozo paper. I got a little off both types. The thin Kozo has lines running through it. They are more or less uniform, about an inch and a half apart, going all the way down (or across, depending on the orientation of the paper). I'm sure it is a result of the manufacturing process.
    Did you notice this on your B&S paper?
    Thanks,
    Steve

    Does anyone have any scans of prints using the B&S kozo paper for platinum/palladium printing? Im interested in seeing how a print looks on this paper, thanks
