DEAR RICHARD,
Do you know if I might be able to make alkali fixer (ammonium
thiosulfate) by mixing Ammonium Chloride or just Ammonia and Sodium
Thiosulfate? If so, in what quantities do I mix to create either a stock
solution or a working solution?
CHEERS!
BOB

Thanks Richard,
I guess I am just best asking Monochrome Photography themselves.
As for your comments regarding "drivel", I bought the stuff for use with
Dixctol.
But if I can just use regular ol' Ilford rapid fixer then great!
