    I have read that the hydroquinone in this developer does not last nearly as long as the other developing agents. So I wonder if the "better tones" are just the result of the HQ becoming less potent. Which leads one to the AA version without HQ. I have read the Adams books, and Jack's Specs:

    http://www.jackspcs.com/chemdesc.htm (glycin description)

    http://www.jackspcs.com/pd130a.htm (130 formula, AA version)

    Thanks to an APUG member, I am now for the first time the proud owner of 100g of glycin, which came to me via Alaska then Brisbane. It's now in my freezer, awaiting beng made into 130. Given its reputation for keeping better in solution than as a powder, I have a few questions which the experienced members might be able to address:

    It would take me a while to use 100g of glycin, so would it be better to make up the whole amount as 130 stock rather than keep some as powder?

    Could I make it up double strength to help its keeping?

    Did Tom Hoskinson's experiment of using TEA to make up a "solution A" stock work well? (see http://www.apug.org/forums/forum37/8...in-anyone.html)

    Should I consider leaving out the hydroquinone or reducing it? (Since AA preferred leaving it out, and others have noted the "improvement" with age)

    I use a Nova vertical slot processor in a tiny darkroom, so making up alternative developers for problem negatives is usually avoided. But is it worth considering keeping the HQ separate and adding a bit if required? I understand the the print tone is cooler with HQ, as well as being more contrasty.

    I always wondered about the Adams HQ addition. It was mixed with a lot of water and adding enough of this solution to approach standard 130 would add an appreciable amount of water an so would dilute the whole thing, probably not what you want if you need a little more contrast. Wouldn't it be better to have the HQ as a concentrate, perhaps in propylene glycol (in which HQ is very soluble)?

    Finally, does anyone know why in the AA version, the sulfite is reduced? I can understand the HQ being eliminated, but why the sulfite?

    The keeping is already good. My current stock solution was mixed in April 2007 and it's still going strong.

    I get 100 grams and mix up 9 litres of stock solution. Use it as fast as you reasonably can, but a year is certainly no problem. Two years, apparently, is not out of the question either. I'm still getting excellent dmax with it.

    Favourite film: do I need to pick only one?

    John,
    good idea with the HQ concentrate. Much easier to handle - something like a concentrated KBr or BTA to dribble in to control fog? Yes, I know, not the same thing, but same idea.

    Locally I can't locate propylene glycol but the ethylene glycol is everywhere.

    As for the sulfite, which is known to 'regenerate' HQ, and does nothing for glycin - so why add it? 'Save the Planet' 50 years on?

    Murray, propylene glycol is used in refrigeration systems. I got mine from Actrol in Moorabbin, and I think they have branches everywhere in Australia.

    I wonder if sodium sulphite (sulfite) is soluble in propylene glycol?

    I just threw out a liter that I mixed two years ago, 1:1. It probably worked OK (it did last month) but it just got too dark to see the print in the tray.

    John, not in my experience.

    Sulfite (Na or K) It is listed as slightly soluble in alcohol
    thus it should be almost insoluble in Propylene glycol

    that would have been PERFECT for
    paper negatives and film
    silver magnets, trickle tanks sold
    artwork often times sold for charity
    PM me for details

    I mixed a 5:1 concentrate of 130 in water a couple years ago and it was just fine, kept long enough for me to use it up. I have a nice Corning heated magnetic stirrer which takes everything into solution very well and mixing a normal batch is no big deal so I gave up the concentrate idea. I make 1 gal. of stock at a time and use it 1+3 so it lasts a few weeks. I use a Glycin film developer also and have never had the Glycin go bad on me before using it up...Evan Clarke

    You should try the Chinese Amidol for developer. It is so inky dark that you can't see the print at all.
