Steve Anchell's books suggest the following fromula:

2. 5 grams Metol
3. 100 grams Sodium Sulfite, anhydrous
4. 30 grams Sodium Chloride
5. Cold water to make 1 liter

Will this formula match Kodak's packaged Microdol-X?
Thanks, Joseph

This formulation is substantially different than the one I published in the Apug Chemistry section (with a modification suggested by Patrick Gainer):

"Here is Ronald W. Anderson's Microdol-X substitute formula. This formula was published in the 1973 Dignan Photographic Newsletter.

Microdol-X Substitute

Water-----------------------750. ml
Metol-------------------------7.5 grams
Sodium Sulfite (anhy)--------100 grams
Sodium Bisulfite----------------7.5 grams
Water to make---------------1.0 liter

This formula works fine with the normal developing times given for Microdol-X (both use 1:3 dilution). The results: The same, even to image tone.

Pat Gainer suggests that adding 30 to 50 grams of canning salt or iodine free table salt to this recipe may result in a reduction in granularity without significantly increasing development time.

Note the increase in the amount of Metol and the addition of 7.5 grams of Sodium Bisulfite which distinguish this formulation from Kodak D23.

This formulation is basically Kodak D-25 with iodine free salt added.
