Some suggestions from Artcraft Chemicals customers, c. 1992
Substitute formula for Microdol-X
Water (125°F) 750 ml
Metol (Elon) 7.5 gms
Sodium Sulfite 100.0 gms
Sodium Metabisulfite 7.5 gm
Water to make 1 liter
Add a pinch of sodium sulfite before
adding the elon. This will prevent the
elon from oxidizing. Use the same time
and temperatures as Microdol-X.

This developer is meant for single shot
usage in a drum processor. 60-65 ml (2
oz is adequate for an 8 x 10 drum and
120-130 ml (4 oz) for the 11 x 14

Use the above undiluted; quantities can
be doubled or even tripled to make 2
more concentrated stock solution which
must then be diluted before use. Shelf
life is about 5 weeks. Discard if the
developer becomes darkened over time.
