Here is an interesting fact. 526 grams of borax decahydrate will dissolve in a liter of glycerol. I dissolved 120 grams in 500 ml, added 10 grams each of Phenidone and ascorbic acid, used 1+50 dilution of this solution to develop Arista Premium 400 for 16 minutes at 70F with excellent results. I think this might be a good stand developer. The pH of the working solution was about 8.5. The borax brings with it the water of crystallization, but at most that would amount to about 56 grams of water. If you have time for such frivolities, it's fun to play with. Even with heat it seems it will not all dissolve, but give it some time.
