    suitability of Ammoniumtetrachloroplatinate for Zia

    I'm trying to speed up my supply of chemicals, and although Bostick and Sullivan are nice folks, they are just too far away for convenience. I had to buy a Pt solution, and I found that I can get it from Lotus, but they only have ammonium version of salt instead of Potassium.

    I'm working with Zia printing, and I'm substituting some of Pd with Pt for better shadow separation and I would like to know if Ammonium Chloroplatinate can be used instead of Potassium Chloroplatinate?

    Thank you
    Marko

    From what I've been checking lately in chemistry supplies, my guess is that the ammonium will be more expensive than the potassium chloroplatinate. Can someone confirm this?

    Though I've never used it my guess is that it will work, okay. I'm not sure that the addition of platinum or substitution of platinum will give better shadow seperation. Check out Mike Ware's site for some additional information about ammonium salts. As far as B&S go they are good vendors and I've never had a problem with them.

    Thank you both for reply.

    Don, it's not that I had problems with them, they are nice people to work with. But problem is in Atlantic Ocean. Things need enormous amount of time to cross it :rolleyes:.

    Marko you may have already seen this on the Bostick&Sullivan site, but check this article out. In it there is a discussion of Mike Ware using ammonium chloroplatinite (not ammonium chloroplatinate I realize).

    So you might try contacting Ware or even Sullivan or Weese to get their input. Like Don, think it is possible, just not sure what the results will be. Let us know how it works out.
