As soon as March 2012, I rediscovered salt as a possible alternative to known thiosulfates fixers.
A 300g/l solution of salt will fix normal B&W films in about 24 hours.
After that date, I started a series of tests in order to make the salt fixer faster.
I came to the conclusion that adding 2ml/liter of a 5% solution of household ammonia to the salt fixer, the time is reduced to as few as 2 hours. In this recipe I also included 2g/l of Potassium Bromide which also contributes to the speeding of the salt fixer. But it may be left away, if time may be longer than 2 hours, let us say 4 hours. Also Potassium Bromide is not a household stuff and this is actually the aim of the thing, no need of expensive products and hard to get!
It is already 5 years ago that I published the 'finding' and slowly this is spreading away.
Early recognized by the Caffenol Master Reinhold, that promoted some discussions about it in forums, I am glad to see that my modest contribute to homemade film development is beeing announced here and there. I found it today at the fine blog of Profesora G. J. Yukavetsky.
My compliments and special thanks!
