APUG - View Single Post - Experiments with Metol and ascorbic acid.

Interesting formula, but there seems to be a lot developer relative to the activity! By comparison, I use a version of MC-TEA plus sulfite that has approximately the following amounts in the working solution. It is slower than the developer you describe here, but not in proportion to the amount of developing agent. Without sulfite, this developer does practically nothing.

1l water
metol 0.3g
ascorbic acid 1.9 g (actually C-1000, health-food store version that is about 40 percent less active than pure ascorbic acid)
triethanolamine 8.3ml
sodium sulfite 10g

Delta 400 35 ml 75F 14min.
