D-76 and Boric Anhydride.
Thanks to the Analyst for replying to my question of Boric Anhydride in
D-76. However, if Kodak state that a certain chemical component is included in a specific processing product in their MSDS then I have no reason to doubt their word, after all why should such a reputable company deliberately mislead their customers? To go back to my original question, I was asking what the function of Boric Acid has in D-76 and how does it differ from Boric Acid? Now here is another question, if you think that the commercially packaged Kodak developer is the D-76d formula, then why does the Kodak product contain close to 110 grams of constituents per litre instead of 123 grams that are in the D-76d formula? Kodak are hardly going to reveal a company secret and I certainly don't expect them to. I was simply asking about the function of Boric Anhydride in Kodak D-76 and how does it differ to Boric Acid? Does anybody out there actually know the answer besides a Kodak chemist? |

None of this matters. Kodak produces a consumer version of D-76 which
is better than the original formula rom the standpoint of consistency and reliability. That's all you have to know. |
