A year or so ago, a friend gave me a box of old photochemistry he had dug out of a high-school darkroom. In that box was an ancient box of Kodak Hypo Clearing Agent. There were three small aluminium bags still intact inside; the contents of these small bags are totally dry and undamaged. Seeing that I'm going to be using FB paper for the Group Print Exchange, I thought that it would be wise to use Hypo Clearing Agent. The only problem with this is that the box I received has no instructions inside.
The outside of the box simply says ''5 packets each to make 1 1/4 US gallons of solution (4.7 litres)''. I assume that one would mix a packet into 4 litres of water at about 40C and then add in 0.7 litres to finish. Do I have it right?
As for use, if I understand correctly, it's one part stock to four parts water, yes?
Any other special things to know when using Hypo Clearing Agent? Is it advised for film as well as FB paper?
