HC110- I made a mistake but everything was fine?

[Jmarmck]

OK thanks Jim. It was in the first paragraph. I went straight to the tables and not see the instructions for mixing the stock solution. Thanks
Yes, I think that the 1:31 from concentrate is probably what I will do.

That is what I did. Read the paragraph just before the tables. It says that the "stock solution" is mixed 1:3. Very poorly written if I may say so myself. If you go through the math in the first table it comes out a 1 part HC110 concentrate to 31 parts of water when using "stock" solution.

Here is the quote:

"To prepare stock solution, dilute one part concentrate with
three parts water......"

Scanning for numbers in the paragraph will not pick up any information.

By the way I know it is correct to mix 1:31 because I did a couple of slides and all my high contrast problems went away. It will work, which is a miracle, but one thing I picked up on is that I was also having focusing problems in the enlarger. No wonder, part of the emulsion was pitted horribly.


Take care,
Richard.

When I first tried HC-110 I read that data sheet 3 x before I got the reference to the stock solution,
guess it might have been the zeal to use it and scanning the tables for the amount to mix that makes
you miss that little tidbit of info, I agree it could have been written or laid out better so that the
info for making the stock solution isn't glossed over..

[1 part concentrate + 3 parts water] = one part stock

[1+3] [1+3] [1+3] [1+3] [1+3] [1+3] [1+3] = seven parts ALL WATER

Add-up the 1's and 3's inside all the brackets in the two lines above (the sum is 32) and now you can see where the "1" part concentrate and the "31" parts of water come from!

"K.I.S.S." version: Dilution B = 1 part concentrate + 31 parts water.
