    Sudden (and not so ) Pyrocat HD Failure

    I had one failure only because I didn't know roughly when stock solution A would expire. After a few months it died. Since it has a rather short shelf life, I mix up only 100ml of stock A. Stock B lasts indefinately so I mix up 1000 ml. I remember that as stock A ages, it also changes colour slightly...that was when I discarded and mixed a new batch. I haven't mixed any up for a while (about a year ago) so I don't rememeber the colour of freshly mixed and slightly aged. I'm sure Sandy will read this and chime in!

    Sandy is in Mexico on Holiday for another week. I got an e-mail from him a couple of days ago.

    He should chime in when he gets back.

    Hypercat addresses the problem of keeping properties, and others as well.

    510-Pyro won't die on you, and offers other advantages as well.

    Sounds like a Photographers Forumlary failure. I mix my own Pyrocat HD from scratch & have been using it since shortly after Sandy King came out with it. Haven't had a failure and have used some stored 6 months in bottles partly used.

    I don't use forumlary for anything as I have had failures/bad product from them in the past.

    Try mixing your own and you will know it is fresh. Easy to do and economical as well.

    Perhaps PF would be interested to know what's been going on for some of us. Anyone mind if we send them a link to this thread? They seemed like nice enough folks and might be willing to put it right for anyone who has had trouble. I thought it was just my fault for not using it all in under a week. The failure did spoil 5 shots for me though. In terms of mixing, some of us need smaller amounts, and fewer concentrated chems laying around, so having a liquid is really so handy.
    Also, perhaps when Sandy gets back in town he might chip in on the subject. Pyrocat HD does give nice results.

    I think that the Forumlary would appreciate any problems that their product exhibits so that they can work on a resolution. Fire away.

    In addition to the marvelous results one can obtain with Pyrocat HD, the research and commitment that went into developing this forumlation and Sandy's willingness to share this with us via his A+ article is just to good to be true. A testament to a gracious and consummate professional.

    Stay The Course!

    I sent PF a note inviting them to post a response here to enlighten us. It's a holiday this coming Monday, and Sunday today, so it might take a minute to see what they say.

    I've also had recent problems with PF chemicals. I went to mix a dry pack of the Wimberly wd2d+. When I mixed the A solution it turned a deep dark orange. It looks as though they used sodium carbonate in place of the sodium bisulfite in the A solution. This happened in two consecutive Kits. I just discarded it and ordered bulk chemicals.
