KODAK R-10 BLEACH

Part A:
20 g  Ammonium Dichromate
14 mL Sulfuric Acid (or 42 g Sodium Bisulfate)
One litre water

Part B:
45 g Sodium Chloride
One litre water

Mix 1 part Solution A with 1 Part Solution B with 10 parts water before use.

Bleaching time:Time it takes to clear plus 15 seconds, not to exceed 2 minutes.

Temperature:  20C              Agitation:  Constant

Was used in the dawning of the age of wavefront reconstruction, see sources below, hardly ever used nowadays, but a bleach attributed to Dr. Tung Jeong is a variation of it, and one fo my go-to bleaches for either exact laser wavelength reconstruction of refelction holograms, or to generate surface relief effects.

Shelf life: This solution stores indefinitely, but should be dumped when it takes longer than a couple of minutes to clear.
