Heck - nothin' to SO2. They work with it all the time at the Chevron refinery across town, and it has
only blown up once this summer, and doubled our gasoline price only for a couple of months. Things
are almost back to normal now.
Well, I forgot to add that they also bubble HBr gas into TEA to make the Bromide adduct to supply the pH balance and the Bromide ion as antifoggant.
I think I will just continue to buy mine from Kodak. Maybe if I buy a bottle a month for the next year or two I'll have a large enough supply for my personal use.
:D And probably a large enough supply to qualify as a large quantity generator for the EPA. :whistling:
I think Champion will continue with HC-110 no matter what happens with Kodak . If it does go away I imagine we will have much bigger problems to worry about.
I use D76.
I loved HC-110 with Tri-X before they reformulated Tri-X and the developing times for dilution B are now too short for roll film on a reel. I have always found the grain structure and shadow density produced by the TX/HC110B combo to be much more to my liking than D-76. Rodinol has wonderful qualities, but for me HC-110 was it.
Another thing about shelf life, I had someone give me bottles of very old HC-110. He said it worked fine. I saw a big difference in base fog, highlight separation, and D-Max areas when I processes a test roll (AKA a roll my wife shot). So it's shelf life is not infinite. Now that I got my old M2 repaired and fitted with a nice Summicron M lens, I'm playing with Tri-X in Rodinol, and T-Max 400 in HC-110B. Neither will be like the TX in HC-110. Sad face here.
