    Pat Gainer and Pyrocat-MC

    All of us learn from and have been inspired in our work by others. For me that list includes some of the early proponents of modern pyro staining developers, includiing John Wimberely and Gordon Hutchings, and even Barry Thornton whose Diaxactol formula appeared at about the same time as my Pyrocat-HD formula. I am also appreciative for the published research of Grant Haist, which has been a great resource. And Ron Mowery is a real living person, and friend, who has provided much inspiration and good advice.

    Now, to the Pyrocat-MC formula. Some know of this, others not. The original Pyrocat-HD formula was developed in the late 1990s and has been available in kit from from various sources since about 2000. At this point one can buy it in kit form from many sources, both in the US and abroad. That includes Photographer's Formulary in Montana, which has worked with me extensively to refine the product.

    OK, about Pyrocat-MC. Some years ago I set out to experiment with the Pyrocat-HD formula and came up with a very new developer that used metol in small amount to replace the phenidone in Pyrocat-HD. I called this Pyrocat-M, for the combination of Pyrocatechin(catechol) + metol. A few people mixed the formula, but it was basically not taking off. Then, Pat Gainer suggested a method for mixing the Pyrocat-M formula in glycol. For this he exchanged the metabisulfite with ascorbic acid, and proved an efficient method for mixing the various ingredients in glyol.

    Not long after Pat Gainer sent me the key for this mixture I asked Formulary to start mixing Pyrocat-MC in glycol. It has proven to be a fairly popular developer.

    Some time after Formulary started to offer the Pyrocat-MC kit I wrote Pat and offered to share any royalties from the formula. Pat replied that all he wanted was recognition for his part in the development of Pyrocat-MC. I have on many ocassions on this forum tried to convey that participation. Time has passed, and the link may have grown dim for some.

    So I take this opportunity to again state the facts. Pyrocat-MC is the work of both Sandy King and Pat Gainer, in about equal parts as I see things. I thank Pat for his help, and now as always appreciate his wisdom and advice.

    Hope this is clear. I wanted to write this now, because in some years the knowledge might disappear. None of us is getting younger.

    I have been sitting here half an hour trying to think of what to say. The best thing I can think of is what you all know already. Sandy King is a gentlemean and a scholar.

    Thanks Sandy and Pat..
    Pyrocat MC has been my main developer the last two and half year and i don't see it being replaced anytime soon. It works well for both continuos agitation and semi stand, is very economical and versatile.

    Thanks for making this developer accessible for those of us who enjoy mixing from scratch.

    At a time when greedy, selfish, and dishonest people have so overwhelmingly wreaked havoc on our American and world economies, it's nice to see an unselfish, inclusive and generous acknowledgment of a colleague for no apparent reason other than just to do so. You go there, Sandy.

    Thanks for posting this Sandy. I haven't tried using Pat's developers for film yet, but I have used his older formulas for printing. I have used both the metol and phenidone versions as mixed for paper and have gotten nice results. I would also like to take this opportunity to thank Pat for sharing his knowledge with us, and to thank you for the Pyrocat family of developers.

    I couldn't have said that better, John! Absolutely true.

    I have used Pyrocat-MC quite a bit, and like it for its versatility. It's a great gift to the photography community, and so is having both Pat and Sandy participate, offering help and advice for those that wonder or in trouble.

    We are thankful for what you do!

    Thank you Sandy for writing this. Your contributions, and Pat's are done in a most generous and open manner that is very refreshing and much needed today. Thank you both!

    Ditto what John said. I have been developing solely with Pyrocat-HD for four years now and have followed numerous discussions concerning its development over the years. Its been exciting to read Pat and Sandy's threads as these developments unfolded. Many thanks Pat and Sandy. (Which reminds me, I need to order some more of the glycol-based stuff!)
