Hubl's Glycin Paste

pavelt2tk0 · Nov 7, 2008

Yes, point #4 is a hard stuff - that is why it was written to add very small amounts Non-distilled water should work, however, it influences pH, so the next batch you do may have slightly different developing times. Be sure to shake it for a couple of minutes very well before you dilute the developer. All the concentrate mass must be homogenius before use.

Hubl's is one of those artifacts from LONG LONG AGO that can be amended for the images we make today, There isn't any reason to mix a paste, unless you are traveling through 1905 Europe and want to develop film in your rail car or hotel and don't want to mix a developer at room temperature from powder. By the '20s, folks were generally using the same proportions but making a more wieldy solution. There were slight variations in proportion, and Sodium Carbonate was substituted readily.

A common version from the late 1930's was usually called 'Glycin-Carbonate for Slow Tank Development"
This version from Ed. Lowe, 1939

Sulfite 15 grams
Glycin 60 grams
Sod. Carb. anhy 15
Water, to 2 liters

Dilute 1 to 10.

Another formula from the same time that Lowe mentions is by LM Condax, for color sep negs.

Water 1 liter
Sulfite 50 grams
Glycin 9 grams
Kodalk 40 grams.

Then, there is the ultimate glycin developer, Crawley's FX-2.

But these, and several more, all cousins of the old Hubl paste.

a glycin developer, excellent for stand development, popular from the early 20th century (reference Cassell's Cyclopedia of Photography and Anchell & Troop)

hot water (125F / 52C) 500ml
sodium sulfite 165g
glycin 135g

mix well - takes some time to get all the glycin to dissolve
then add

potassium carbonate, crystaline 625g
water to 1000ml

I'll give this a try. I'm tired of throwing away old, brown glycin. I use it for ansco 130, which requires 11g, but the smallest amount available from photographer's Formulary is 10g. The next up is 100g, and with the long life of 130 I usually end up pitching some.

If a paper developer calls for 11 grams, and you only have 10, what do you think will happen if you only use 10 ? IT IS THE SAME FORMULA. You'll never see the difference.

I put my glycin in a black plastic bag, seal it, and put it in my darkroom (chemical) refrigerator. That helps a lot!

OK : Question: some of you folks state its suppose to be like a paste when finished ? well mine is two tone liquid I have attached a foto , any thoughts , I had my chemicals pre-mesured since I do not have a scale etc : I mixed the chemicals as stated [ except distilled water] using 125 degree water as the instruction's stated in hubl's formular = 165 grams Sodium Sulfite and then 135 grams of Glycin and then 400 grams of Potassium Carbonate, Anhydrous ! Has this happened to others or just me ?? Thanks folks :

Looks like it needs more stirring. Mine is a uniform past with a white to brick red color depending on the Glycin. It is similar to what you see early in the mixing process, so that is why I suggest more stirring. Mine is like whipped cream when done, and uniform.

PE Should I reheat it and stir it or just stir it :

Photo Engineer · Nov 8, 2008

I really don't know. I would guess both together might be better than either, but stir gently. Don't mix in too much air.

Don't heat it and stirr again - your one is ok. Shake it very well right before use. It's consistency depends much on the quality of potassium carbonate and sulfite. But it works fine anyway.

I'm making several liters per month of this paste, and eveyr time it is different if I take different carbonate. When the carbonate is very good, paste is a two tone liquid like yours, sometimes it is like a cream (this happens when I use potassium carbonate wich gives white precipitate when it is diluted in water).

But I found no difference in the development results of all this batches.

pavelt2tk0 · Dec 5, 2008

And one more - I use 625 of anhydrous carbonate because in my old book (1917) is written the following: "All recipes of this book suppose to use crystalline potassium carbonate", but for Hubl paste it is written "Use anhydrous potassium carbonate for this recipe".

For those who are using Hubl's Paste, or have used it .... did you notice a change in color of the stock solution?

I mixed my first batch last December. At the time it had a coffee creamer like whitish color. Nowadays, more or less 3 months after mixing, the stock solution has a dark salmon like color and it is getting darker and darker over time. My experience is (very) limited as I'm still experimenting with it so I can not tell if I have noticed a decrease in activity. Hence my question, did you ever noticed a change in color? And did it affect your development times?

Looking forward to hearing from you!

To answer my own question ... the color change is real but development times do not seem to be affected.

Yesterday I used some Hubl's Paste that I mixed in December 2020 and has been stored in an amber brown bottle of glass ever since. The bottle is nearly empty and had a lot of air in it. After a thorough shake I poured out something that looked like black ink. To be honest, I did not had any confidence that this pitch black watery mud would be any good. To my surprise the negs came out looking really good. I have not printed anything yet, but on first sight the contrast, tonality and sharpness look all very good.

Here is the example of Glicin processing in ancient 80-th:

Nowadays it is opinion, that remarkable properties of glicin is a fairytale

You are right, but these changes usually don't influence the result
