Eau de Javelle ( Javel )



Hi,
Since someone may be interested in Javel Water, its mentioned on the Internet and also by Lluis Nadeau, ''Gum Dichromate''  1 9 8 7 .  Page 7 6.  ''ARVEL''
Quote:-
'' For a period of about fifteen years preceding World War  11  the Fabrique de papier FRESSON commercialized a ''different'' Direct Carbon paper called  ARVEL. In an attempt to do away with the sawdust development, the paper was exposed under a negative for a period considerably longer than usual i.e. 5  to 20  times longer.  After exposure, the paper was soaked in a 3  to  4%  solution of Javelle water and the (relatively ) unhardened parts of the image were then dissolved, leaving a positive image.''

I guess there must have been a great number of photographers making successful  Arvel prints over this 15 year period of time. Where are they, now.........the prints and the photographers ?

Javelle water or Javel water (both: zhəvĕl`), Fr. eau de Javelle, aqueous solution of sodium or potassium hypochlorite. It was originally made near the French town of Javelle (now part of Paris) and was the first chemical bleach, a use first demonstrated by C. L. Berthollet in 1785. It was produced by passing chlorine gas through a water solution of potash  After the invention of Javelle water was sometimes produced by reacting the bleaching powder with potash or soda ash Now usually sodium hypochlorite solution, it is used in  and as a disinfectant.

>> For what it is worth--eau de Javel (one "l" is the correct spelling so the
