[pure-silver] Re: Alkali Fix - How to Mix

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!
