HC-110 went wrong

Well this is one of those mistakes you only make once!

I too find the syringe/syrup method much better. I started with this about a year ago and love it. The syrurp does discolor some in the jug but I've not had any surprises due to oxidation of the syrup.
 
I use something in between the syringe method and the stock method.

I mix up stock, but I do it in smaller batches.

I do not like the air bubble in syringes. I do not like measuring things that are so thick using syringes, as part of the measurement sticks to the sides, nor do I like cleaning the syringes. Consistency is better if you mix larger batches, as any slight inconsistencies are not so magnified in effect.

I mix up either 250 mL or 500 mL of stock at a time, and stow it in amber glass bottles. When I get to the halfway mark in my bottle of syrup, I put in in amber glass bottles as well. Stock has lasted me 8 months in a half full bottle this way with no change in contrast on my negs. I have not tried any longer.
 
I process very little film* so I go through very little chemistry. The HC110 is going past a year in the bottle and still going strong as of a month ago. (*Reason, doing more printing so I can see all the developing I did in 08.)

I just don't like doing it. I find it to be one more little annoying thing to fiddle with, when I could just mix stock every few batches, and pour it straight into a graduate.

I use a syringe for Rodinal, but not HC.
 
Good syringe technique will prevent bubbles, I just hate it when back technique is posted on the internet as fact. Now when someone does a search they will see the post and might not try a good technique.

Quite a dramatic reaction, considering that, "I do not like the air bubble in syringes" is what I wrote.

I did not state bad technique as fact. You miscomprehended and/or misstated something I wrote. Therefore there is no reason to "hate" what I did...because I did not do what you hate!

So, "good syringe technique" gets rid of the bubble. I do this with Rodinal...but not with HC...because I do not like using syrup in a syringe...because it is syrupy!

Then - for photography, 1:31 is considered: 1 part chemical to 31 parts water for a total of 32 oz., or simply one part of 'a' with 31 parts of 'b'?

Oh oh... this could get interesting. :munch:
I think a thread on this topic became quite colourful a year or two ago. (Right up there with tap water vs distilled, measuring by weight vs volume, understanding EI and the demise of Kodachrome... sigh.)

Doesn't 1 part a with 31 parts b also add up to 32 ?

Ilford shows the measurements as 1+x rather than 1:x, which eliminates a lot of confusion. On the HC110 bottle, kodak says 1 part stock and x parts water, which should be the same thing as 1+x.
 
I would not use the terms "part A" or "part B" in regards to HC-110, because the official Kodak dilutions are also described with letters.

Hikingman, you can indeed easily mix up a U.S. quart (32 U.S. ounces) of HC working solution B by mixing one ounce of concentrate ("syrup") with 31 ounces of water. I used to do this when I used quarts. Now, I use liters, and I find mixing small batches of stock first to be easier with the metric units.

You guys know they sell these amazing things called graduated cylinders, right?
