Pyrocatechine

Discovered in 1839 by H. Reinsch; Pyrocatechine saw little use in photography because it could not be made chemically pure, plus the cost of it was high. But by 1898, all that was about to change. Dr Ludwig Ellon & Co. Chemical Works of Charlottenburg, Germany, had discovered how to make it chem...

Re: Is my Microphen formula correct?

Hello Ian, how are you today? A few years back, Keith made the post sited below, on another thread dealing with this same subject. Do you happen to know what the formula listed below is? It is not like any Microphen formula that I have seen. It got my interest because Edward Lowe like to include T.S...

Champlin formulas No. 7 and No. 9, plus FR X33

I remember FR X33, I first saw it at Detroit Camera Shop in 1963. I never thought that any one would be interested in it. I do have the original formula for that product, it is as follows: FR X33 Film Developer Water 22 oz. Diotel 120 grains Monotol 75 grains Sodium Sulfite 2.25 oz. Glycin 22.5 grai...

Re: Are you looking for Lithographic Developers formulas

Hi Ornello: Yes, I could buy "Rodinal", but yet again..., why. I discovered that home brewing formulas is a lot more fun than buying them. When you buy someone's formula, you simply read about their work and the results that they achieved. And you spend your valuable time trying to re-crea...

Are you looking for Lithographic Developers formulas

Well, I am not looking for them. But for those of you that are, I will not allow you guys to be forgotten. I do not know that much about those type of developers, but I am willing to learn. So any thing that you or anyone else teach me will be welcome. What I have been told is that lithographic deve...

Re: Rodinal, its true story and formula.

O.K.: How that we have seen the formula in a Agfa ad era 1902. I feel that it is only fair that I post the formula, which most people already know. But there is a small secret that was missing. It is "lithium hydroxide". I do not recommend using it. It cost $46.16 for 100g at Fisher Scient...

Re: Rodinal, its true story and formula.

I want thank everyone for their support. But YAHOO!!!!! I found it. I was looking for something else. In fact, I was looking for the chemical make up of "edinol". I wanted to see what modern developing agent today that I could use as a substitute for it. When Ka-Boom!!!, theres the informa...

Re: Rodinal, its true story and formula.

I discovered that hatreds and dislikes, back in the 1890’s, are no different than the way things are today. Dr. James H. Stebbins, (a professor of “salts”, discovered “eikonogen”, but lost the discovery to Dr. M. Andresen) Dr. J. Hauff (inventor of Amidol), Dr. C. Ehrmann, Dr. Stoltez, Lumiere of Pa...

Re: Rodinal, its true story and formula.

I will put a stop on my posts, until I clear something up. I came across information on Dr. James H. Stebbin Jr., that I was completely unaware of. His complete //background// and history is coming clear and open, the more I read about this man. He was a highly respected member of the American Chemi...

Re: Rodinal, its true story and formula.

The "original" formula for "Rodinal" was published in 1891, by James H. Stebbins Jr, in his magazine "American Amateur Photographer" You will need to Goggle "American Amateur Photographer" . You are looking for volume 3, 1891. When the page comes up, will you ...

Re: Rodinal, its true story and formula.

"Rodinal", is an outstanding developer, when used within its abilities. In 1891, the formula for "Rodinal" was new and different. But it never became as popular on the Amateur Photographer circuit as it could have, because of the lack of para-aminophenol in America and other coun...

Re: Rodinal, its true story and formula.

Ornello: I must state that you are completely correct on that issue. Most of the developers today and past were based on slow films/Plates or slides. Because they were all "hand made" gelatin base emulsions. ASA for most was 25, other fell between that and 50. But not much more. In the 189...
