Dektol, Permanganate Bleach
My first successful attempt! A previous try ended up softening and washing away the emulsion at the second development stage leaving a clear strip of acetate. After some advice from friends at Kodak, I tested the ph and raised to 1.5 along and lessened the amount of time in the bleach to end up with this result.

Dektol (1st Developer)
Kodak Potassium Permanganate Bleach
Clearing Bath
100w Incandescent Bulb Re-exposure
Dektol (2nd Developer)
PROCESS STEPS
Dektol (1:3 Dilution) Develop: 7 minutes (agitate)
Rinse: 2 minutes (agitate)
Kodak Permaganate Bleach: 2 minutes (agitate)
Rinse: 1 minute (agitate) Rest of directions can be done with tank open under subdued light and just dumping the bath after each step.
Open up tank – dump all liquids from tank. Rinse film spiral under running water for 1 minute.
Clearing Bath: 2 minutes (agitate)
Rinse: 1 minute (agitate)
Re-expose: hold to 100W bulb light source for 2.5 minutes - turning the reel so the light is evenly exposed.
Dektol Re-Develop: 5 minutes (agitate)
Rinse: 2 minutes (running water)
Fix: 4 minutes (agitate)
Rinse: 5 minutes (running water)
Add few drops of Wetting Agent - 5 minutes - agitate slightly to avoid bubbles
Hang to dry (emulsion side out).
NOTE: After mixing the bleach per instructions from Kodak, I tested the pH to .8. I raised the pH using a concentrated NaOH alkaline solution to get the bleach to 1.5
NaOH Solution: Dissolve 50 grams of Sodium Hydroxide (NaOH) in 100mL of water
Had to add about 30-40ml to raise about 3L of bleach. Added small amounts and measured until it got to the target.
