Re: The Fresson / Arvel Process,Etc., and Eau de Javelle
John,
Then we have 2 different formulae; the Javelle formula I have is 250ml water
with 4g. sodium carbonate and 3 grams sodium hypochlorite and at time of use
mixed with another 250ml water....a different solution than you are saying,
below.
I wonder if they use this with Fresson paper or not, because the point of
the article was that using this made the use of sawdust unnecessary. Or, as
the article says, "outdated." Eau de Javel he says is due to G. Schweitzer,
editor of Photo-Revue. Uses a long print exposure (up to twentyfold that of
normal carbon tissue) and put it face down in this bath 2-5 min, etc. etc.
But you have done Fresson, I am assuming, so probably know much more than I.

Chris and ALL,
Chris, you thought, '' So if one mixed a little washing soda
into the bleach it should approximate Javelle''.
NO ! !
Please note that only one ounce of KoCl (bleach ) is diluted with 36
ounces of water to give a working solution which is Eau de Javelle for
the Fresson / Arvel process.
Happy hunting .

To clarify a little further and to quote the next para in Nadeau's, ''Gum
Dichromate.'' 1987. Page 76 Chapter V1:-
''Mouret, mentioning the work of Charles W . Miller writes :
''Early in the morning, he places a piece of sensitized Fresson paper in
contact with a paper negative outside of the window, and leaves it there
all day long without the least inspection. In the evening, he transfers
the paper into the cold water bath for 4 minutes and then into another
tray containing a mixture of 1 ounce of Javelle water and 3 6 ounces of
ordinary tap water. Now the paper must be watched very carefully, and as
soon as the edges begin to lighten it must be instantly removed and placed
either on a glass or tin plate, or in an empty tray. It may now be
sprayed carefully under the tap, or better with the aid of a rubber hose
carrying a glass or hard rubber tip, to enable the operator to direct a
fine jet of water just at the point where it is momentarily required. The
entire surface must be treated in this fashion, until the desired degree
of density has been reached, whereupon the picture may be hung up for
drying.''

American Annual of Photography. (1929 ) pp 179 -182 ''
