No such thing as a dumb question,right? I am about to work with HC-110 developer again after some time away. Front of the label says "to make 2 U.S.gal lons of working solution/ Makes .5 gallons of stock. So far so good this jives w ith Kodak's web site info "mix concentrate 1:3 to make working solution". Back to label under mixing instructions. "First prepare the stock solution by pouring this concentrate into reclosable 1 - gallon container. Rinse the concentrate bottle with 8 oz and pour the rinse into the container. Add 76 fl. oz of water to bring the total volume to 112 oz. Shake etc. etc. (not a half gallon) The great yellow K is not speaking clearly to me. Can someone please show me the way? TIA Larry
Larry, Go to the Kodak website (www.kodak.com) and search for publication J- 24. This will cantain all the info you ever wanted about HC-110. Regards, ;^D)
A misprinted label perhaps? The information that I have is that HC-110 concentrate is mixed 1:3 to make stock solution. Thus, a 16 oz. bottle of concentrate makes 64 oz. of stock solution. Could Kodak have changed things?
Larry: I mix the concentrate as you indicated for the stock solution. It makes a half-gallon of stock, give or take a little. I then pour the stock solution into 10 oz. brown glass bottles (plastic will probably work o.k.) I use dilution B (7 to 1) for a working solution. To make this dilution, I dump the bottle of stock solution into a gallon jug and add 7 bottles of water. That amount is perfect for the old hard rubber developing tanks I use. Fill the small bottles of stock solution to the very top and cap tightly. The stock solution will last for months if sealed tightly with no air space in the bottle. The bottle of concentrate I have in my hot little hand says rinse the bottle in FOUR ounces of water and a pour into a half-gallon jug. Then you add 44 fluid ounces of water to make one-half gallon of stock. You then add 1 1/2 gallons of water to make two gallons of Dilution A working solution. I have followed the instructions on the bottle of concentrate for years without problems. I never use dilution A. Hope this helps, Doug.
It looks like they've gotten their labels mixed up. Do you have a 16 oz bottle or a 28 oz bottle of concentrate? The front of the label is correct for a 16 oz bottle, whereas their mixing instructions are correct for the 28 oz bottle of concentrate.
Thanks the help all,seems the bottle must be mixed up,no pun intented, although the info is on one label and a 16oz container the mixing instructions address the 28oz size. Just when I thought it was safe to go back into the darkroom! Larry
By the way, solution B works out to 1:31 from the concentrate. I just mix it directly from the concentrate (e.g., 1 oz concentrate, 31 oz water), and it works fine.
I have been going with the direct from the thick concentrate approach for years with good consistent results at 1:31 also. I use a small medicine cup that is marked at 1/2 oz and 1 oz. Just right for either 1 pint or 1 quart tanks. I add about half the water and use the rest to rinse the cup thoroughly to get it all dissolved.
