Boric Anhydride in Kodak D-76 commercially developer.
My favourite developer Kodak D-76 according to the material safety sheets
contains a component called Boric Anhydride which at first I thought was just another name for Boric Acid until I read the CAS registry # is (1303-86-2) and the CAS # for Boric Acid is (10043-35-3). Does this component work in the same way as Boric Acid in that it helps to maintain a more stable pH? I also read that it is included with Microdol-X. It seems that ID11 is still made by Ilford to the original formula with the inclusion of Sodium Tripolyphosphate for use as a sequestering agent.
