As you will notice I am sorta new here. Was a member a number of years ago and just fell off the map. Looking to branch out and try some new techniques. I have some I'm going to say an old version of HC-110. It's 16 fl oz bottle dark red and thick. I have had these for at least 20 years and I think they are from the 70's. I have 5 or 6 bottles. None of the have been opened.
I'm questioning the dilution measurements of this developer. First you have to make a stock solution, adding the 16 oz of developer to 48 oz of water to make 64 oz. From there you make your working solution. Their direction, on the bottle, for working solution B is 1 part of the stock solution to 7 parts of water. How if at all does this relate to the solutions of today, 1 to 31? Another example is 1 to 11 for solution E.
Thanks
