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 :
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.
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".
